Zed Moves

I have been doing all kinds of things to get NewOldHouse ready for us to move. The exterior is painted. The interior is almost ready for paint after many more days of caulking and masking. Because we knew the end of the dry days were almost upon us, I took a couple days off work so Boo and I could get after some outside stuff. Today's post covers that.

Back to Back Chicken Shacks
Zed's new home
That's right. This property has two 8' x 12' locking sheds right next to each other that the prior owners were using as chicken shacks. The one closer to the house looked to be in better shape, while it's Furthur (see what I did there?) twin has a failing roof. We decided that we would clear them of chicken scat, hay and whatever else we found and then determine what to do with them. After a few minutes of working on the better-shape shed with a respirator and a shovel, it was clear that it was salvage-able, and had not had any rodent activity (no rat scat). I got the nasty out first with a shovel, then with a rake, then a broom and finally with a high-pressure hose. Once cleared, I sprayed it with house-wash and rinsed it down. The front-most section of flooring will need a replacement sheet of plywood/chipboard, but the rest of the shed will work, and serve as my car-parts/tool shed until a more permanent shop can be constructed.

The other shed did not see as much progress. The roof and the entire floor will need to be replaced. Still, that's a couple hundred dollars of plywood (plus some roofing material that we happen to have lying around) to repair a shed that would cost, like, 5K(US$) new. It will hold garden implements and supplies, and can do that even with a rotted floor... until we can get some time to repair it. Eventually, the lawn tractor will even get parked in there. I will return to the scat-removal and clean-up of the FurthurShed after we move. The repairs will probably wait until next year. But, to help protect it for one more year, Boo and I stapled thick, large black garbage bags (flat) over the holes in the roof. Now, that sounds pretty ShadeTree, and it absolutely is. Still, after a couple relatively heavy rains since, the inside of that shack is dry, so the wood that is not rotted will not get worse before we can get out there next year and repair them right.

Zed in Motion
man-hunt on
With the sheds ready to be pressed into service, we cleared the area where the 2 carports were assembled, around the back of the house. The grass was cut down to the dirt, all of the little weedy shrubs were cut down, and then the car ports were set in place: as tight to the house as they could go without bumping into the siding. Last, we laid out a tarp to act as a vapor barrier between the earth and Zed's underside. We were ready to move Zed. Before I started working on how to tow him, I thought I could try to drive him. Sure, he has no interior, no glass, no side mirrors, no tail lights, a 4-year-expired registration, it's raining, it's garbage day and there is an active man-hunt in the neighborhood by Beaverton's finest. Still, it's worth trying; worst case, I have to tow him. Regardless of outcome, it would be a funny story.

Long ago, I had drained Zed of gas by loosening the fuel line in the engine compartment and firing up the fuel pump, pumping the fuel into a gas can that I then used to fill the lawn mower. I had not tried to start Zed again. Knowing this day was coming, I had charged his battery and then disconnected the negative terminal (saving the charge). After confirming the battery was full (12.5V), I poured a fresh gallon of gas into his tank, hooked up the negative cable to the battery, flipped the ignition and fuel pump switches and tuned the key. BahRoom... he fired right up. Now, even though I had pumped the fuel out, there remained some old gas remnants in the lines or the injectors were kinda fouled. Regardless, Zed ran rough, and did not want to idle. I babied him along until he settled down and idled. Cool. So he runs. I took the next step and tried to back him up, but he wouldn't budge. I felt like his brakes were rusted on. I tried to high-rev reverse to break the brakes free, but that didn't work. I suspected the rear brakes were rusted tight from sitting motionless for a couple of years.

the "nicer" shack, before
Undeterred, I chocked his front wheels. I raised the passenger side rear wheel by the axle with my trolley-jack and removed the wheel. I shot rust buster onto the brake shoes (which looked pretty much worn to nothing anyway) and then hit the caliper with a framing hammer, sometimes using a flattened chisel on the pad, to loosen the rust-hold. After a few cycles, I could see that the brake shoe no longer held to the rotor. So, I slapped the wheel back on, lowered the jack. I repeated this on the driver side... all while keeping my head on a swivel for the police escapee (hence, no pictures). Satisfied, I pulled the wheel chocks. I topped off the brake fluid to make sure the front calipers would have the most capability of stopping us, since the rears were now covered in oil.

Feeling confident, I put my red plastic toolbox on the floor for a make-shift seat to try to drive Zed again. I bungie-corded the driver door shut, and fired him up. He started a little rough again, but settled into an idle quickly. I popped him into reverse and Zed started to back up. I navigated around the shrub on the corner of the parking spot and then down my not-quite-straight driveway by looking through the passenger-side tail light hole. It being garbage day, I had to wait for the truck to clear out of the cul-de-sac, but that let the engine idle a little more, working more of that bad gas out and good gas in.

the "nicer" shack, after
The brakes took some pumping to get to a full stop, but I figured it was mid-day during a work-week and I was driving about a block-and-a-half, so the risk was low. I got the rest of the way out of the driveway, put Zed into first, and puttered down the street, stopped at the sign on the corner, and turned onto the more highly-used street to the NewOldHouse. I could see cop cars down the street both behind me and in front of me (picture above shows cops 2 doors down from our new house), but no cops between me and the NewOldHouse. I went for it. I puttered to the house, straight down the drive and around the back. It took a 3-point turn, but Zed now sits on top of a grey tarp, underneath a carport, ready for me to revisit once we're moved (shown in the top picture).

I think that's about it for today. Boo and I are finding that with each potential challenge presented by this house, it always looks worse than it really is. From the chicken shacks to the interior plaster, once things get cleaned, the condition underneath is not nearly as bad as it looked. I continue to get more excited about what this new home, and a potential new shop, could mean.

Zed Body Assembled

Quick post today. This past weekend, Boo, C and I put the hood, rear hatch and doors onto Zed, in that order. That's really all there is today, but we did learn some things, as we always do, along the way.

Hood
hood, door on
We started with the hood, not because we thought it would be easiest, but because it was the closest to the car, and we didn't want to trip over it. When I removed the hood to shoot it, the hood was open. Now, that sounds kind of obvious, but earlier, when I had it off, it had been closed. Back then, I could not get the mounting brackets to shift from closed to open position after I removed it. After all the prep work, I installed it to get the fenders and such to line up. When it came time to paint, I opened the hood and removed it vertically. I was by myself, but I figured if I scratched or dropped it as I removed it, it was not a big deal. For install, though, I needed hands to hold it steady or it would get scratched and that would have been super disappointing. I held one side and C held the other while Boo got all bendy, reaching into the engine bay with the bolts. Once they were fingered in, we lowered the hood (still unlatched) to put on the other panels.

Rear Hatch
hatch, door on
The rear hatch was the easiest of all 4 to install. C and I each held it aloft while Boo fingered on the nuts. The hinges were attached to the body, so they wanted to lay down in a way that we could not get to the underside to put on the nuts. C found some scrap foam and stuffed it under each of the hinges so they popped up enough to get the nuts on. The hatch still needs some adjustment to sit a little higher, I think, but I will probably wait on that until after I have the seal installed so I can get it where it needs to go. I figure I would have to adjust it after the seal goes on anyway.

Passenger Door
C and I planning
For the doors, I left the hinges installed against the car, and removed the bolts from the hinges into the doors. I did this for 2 reasons. First, and most obvious, the bolts that run through the hinges into the body are mostly covered by the fenders when they are installed... like they are now. With the body kit epoxied in place, those fenders are going nowhere. Second, the majority of the install wiggle is in the bolts the go into the car body. Once I got the doors where I wanted them before the last tear-down for paint, it is much easier to get them back where they belong with just the hinge-to-door bolts. Still, this is at least a 2-person operation: one holding the door (from the inside: protect the paint) and another threading in the bolts. I held the door, and moved it as requested while C did the threading. Boo, meanwhile, moved car-port supports and such out of the way.

Driver Door
The driver door was probably the hardest. Consider that the person doing the bolt threading needs to reach past the door from the inside, placing your head where the steering wheel is. Still, the process is the same: one person holds the door steady while the other threads the bolts. We took turns and after about 30 minutes we had the door on.

Front Bumper Adjust
bumper not yet adjusted
At this point, I cut C and Boo loose to get after their own Saturday afternoons while I fiddled with alignment of the various panels. I started with and got the hood square and evenly spaced on either side. I had to loosen the headlight bucket on the passenger side and push it outward, but otherwise the hood aligned relatively easily (read: 30 minutes). The doors latch, and they installed right where they were before, so I will probably leave them be until after the seals go in, like the rear hatch. Because of the nature of the latching mechanism for the doors, there really isn't very much forward/aft movement available, leaving just the height that you would really adjust. I am satisfied that the height is spot on, but once the weight of the glass is added, I may need to adjust them upward to compensate.

While standing back, admiring the front end, I noticed that the front bumper was much closer to the bottom of the passenger side headlight bucket than the driver side. It was a noticeable 10mm difference. I loosened the nuts holding the front bumper bar and tried to lower the passenger side or raise the driver side. It made very little difference (maybe 1-2mm). I had to loosen the front bumper brackets where they mount to the car and shim the driver side to make up the difference. They are exactly even now, but it took some doing.

Well, that's it for today. We have some housing things going on, so I'll probably go dark on the blog for a while. We had an unexpected opportunity to grab a small farmhouse on a large lot around the way. So, my time will be taken with home repair projects and then moving. Suffice to day, I will probably not be doing anything major on a car until winter.

Zed Shot

Following the post from last week, I spent this past weekend getting Zed (1979 Datsun 280zx) painted. This has been such a long time coming, it is really hard to believe the painting is over. I may circle-back around and shoot some touch-up clear coat some day, but for now, the painting is complete. I have not color-sanded nor cut/buffed, but that isn't technically painting.... and I'm not going to do that for a while anyway. Unless I change my mind, cuz that never happens. About that painting...

Scrapping Booger Epoxy
base shot
I concluded my efforts the prior weekend with removing the clamps and confirming that the bumpers held in place. This confirmation was simply me tugging on them in various directions. Everything set right. Starting Saturday morning, I got after reducing the epoxy spread along the seams of the front bumper. Recall, I put that clear epoxy all over where you can't see, but wanted to make sure it really held to the fenders on the ends. So, I applied a bunch where you couldn't see and then ran a bead along the seam. this stuff sands off in boogers, so rather than suffer that again, as I did with the side skirts, I tried a different method this time.

Using the razor blade, I etched two lines, one a hair above and the other a hair below the seam. Then, using a piece of 320-grt sandpaper, I worked the edge of the epoxy until it lifted off a little bit. I grabbed that edge and pulled off small sheets that left a clean edge along the seam. This took far less time than straight sanding, and left a much cleaner finish. In the final picture below, you really can't see any evidence of epoxy peeking through.

more base
With the epoxy lines clean, I repaired some masking and performed my usual degreaser cleanse. Next, I set up for paint, laying down my air lines and mixing station, getting the supplies in place, etc. In the past, I did not get 100% ready, leaving things like lacquer thinner or a parts-cleaning brush in the garage. Inevitably I would have to open the garage door, letting all that stink into the house, just long enough to grab something. This time, I had my gun set up with the line drier, paint set out on a sheet of crap plywood, tarps on the ground, walls on the carport, etc before I even thought about mixing paint. Once I was set up, I took a break for food. Figure each coat takes about an hour, and I didn't want to be shooting hungry.

Shooting Base
Once fed, I wiped the car and the detached parts with a tack-cloth. I felt ready to go, but a little anxious after borking it the last time. I had the paint-correct activator this time though, so I was hopeful. Similar to the prior paint shoot, I mixed 20oz at a time, pouring most of the mixture into the hopper on top of the gun, leaving a little in the jar so it wouldn't drip out the air-hole at the top when I'm shooting at a sharp angle. Unlike the last time, I literally used a jar to mix in, versus a plastic measuring cup. The paint would stick to the plastic cup; it doesn't stick to glass. I pre-measured my mix lines (4oz for activator, 12oz on top of that for base), and simply poured in the activator to the first line and filled with color to the second. I hand shake the can of base for a few minutes before each session, and then shake it for a few seconds before each mix into the jar... because this has metal flake in it. I imagine, if this were just color (no flake), I wouldn't need to do that pre-jar shake. I want to make sure there's plenty of flake in each mini-batch.

hood base close-up
Because I failed to set up the gun correctly the last time, I was a little more sensitive this time. I had at least one coat still on the car, so I didn't need multiple coats everywhere, and I didn't have a full gallon left anyway. So, to set up the gun, I roughed-in the pressure by setting the pressure at the compressor to 30. I have read that there is some pressure loss down the lines, so rounding up a couple of pounds is better. I have a pressure regulator with a gauge at the gun plus the pressure control knob on the gun itself. I understand that necking down the pressure only at the paint-gun end of the hose will reduce the pressure, but the volume of air increases. So, by setting the pressure at the tank closer to your end-desired pressure, the volume will not meaningfully change when you lower the pressure at the gun by a few pounds. Anyway, with the pressure set, I hooked up my in-line drier, opened up the paint volume knob and started shooting test fans on one of the replacement hoods I got for ToyoTruck. In my last session, I used some cardboard. I don't know if this made a huge difference, but I figure test-shooting onto auto-steel is probably a better fan-test than paper.

Satisfied I was getting a fan that laid down without orange peel, spitting or thin spots, I set to shooting the arrayed parts (hood, tail gate and doors) and then the main shell. I had thought I had enough paint for 2 coats. I was wrong. When I thought I had enough for 2 coats, I shot the most important stuff first (omitting the door jams), and then did not have enough paint to get the door jams. So, after the weather seals are on, there may be a few spots in the door jams that don't have the coverage the rest of the car enjoys. Since I was out of paint, I just moved on. I figure I can get a rattle can of this paint (9mm metallic) from Eastwood if it really bothers me.

Shooting Clear
hood clear'd
I have read that letting your paint dry for up to 4 hours before applying clear coat is a good idea. Others have said you can shoot it as soon as the directions for the base say you could shoot another coat of base (like 15-20 minutes in my case). I decided that a little extra off-gassing / drying wouldn't hurt so long as I shot the clear coat within 24 hours of the base. Outside of 24 hours, the base needs a scuff for the clear to really adhere. I figured early Sunday afternoon was inside the 24 hour window, since it was now past 4PM. My other options were to shoot right away or wait a few hours and shoot after dark. I didn't like either of those, so I cleaned up the gun, and the work area.

Sunday morning started similar to Saturday afternoon. I already had the walls up and the tarps down. So, I just needed to set up the painting rig. I had chosen Eastwood's Low-VOC High Solids clear. The reviews were not as good as some of their other clear coats, but most of the complaints were about it's ability to flow out the gun. The advice was to include reducer, which I did. The standard mix for the clear is 4-parts clear to 1-part activator. I added about 1.5 parts reducer. Similar to my use of a jar for the paint to get my measurements consistent, I used a different jar for the clear. Otherwise, the process was the same.

rear clear, in the sun
The weather for both Saturday and Sunday was peculiar for the west-of-the-Cascades Pacific Northwest. The sky was overcast, which made painting much easier. When I shot a few weeks ago, it was very sunny. You would think all that light would make it easier to shoot, but it didn't. Seeing the fan and the paint lay down was much harder in all that light. The overcast skies created a flat light that allowed me to see the target and the paint (and clear) much easier. Weeks ago, I used a GunBudd to help me see. This time, I didn't need anything to see. I did, however, have to wait for the weather to warm up to 70*F. It's a really strange feeling, waiting for the air to get above 70* in August, but that's the world we're in, I guess.

front p-side clear'd
The clear laid down very well, and flowed out the gun without issue. I probably could have used a little less reducer, as I suffered a few drips and sags. Still, I was able to get 2 nice coats of clear before I ran out of reducer. As the clear dried, I became less and less concerned about the drips/sags and more pleased with the overall look. From the pictures, everything looks a little wavy, but I'm okay with that. Without the camera, I think it looks amazing and the difference in the way the color looks between sunlit and shadowed is remarkable. In the first clear picture of the hood above, you can see my elbow in the lower right corner reflecting off the hood. My arm is probably 5 feet away, and that's not a shadow (I'm actually facing west); that's the reflection of my arm. I think that describes how deep this paint can look once it's wet sanded, cut and buffed. Thinking of the imperfections, I know I can sand those drips down and the waves will sand flat. I have more clear, so I can re-shoot areas if I really need to. For now, I am going to let everything sit for a few days, and then start gingerly attaching the hood, rear lid and doors.

I don't know for sure what's next. Well, strip the masking, but maybe I'll clean the engine bay and then start re-installing the electrical stuff. Or do I do windows next? I don't know. I suppose the next logical step is to sort through the shed-room and figure out what I have and don't have. Let's not forget, when I inherited this project, it was a basket case. After all the painting, I still have boxes and piles of unlabeled parts. So, I guess the next step is to empty out the jigsaw puzzle pieces and start sorting.

That's it for today. Thanks, as always, for following along-

Orange Peel

Brief post today. For the tl;dr folks, after I let the paint on Zed (1979 280ZX) cure, I looked at it more closely. I definitely did not have enough pressure at the gun, leading to the paint not atomizing well... resulting in some nice orange peel.. pretty much on everything. Today's post touches on that, and then finishes with the bumpers getting installed.

Before I start, today is Boo's birthday. Boo, you are amazing. I am so grateful we found each other, I simply can't express. Your support for my car projects, and tolerance for the corresponding messes has helped make these posts happen. Your embrace of a "Let's See" attitude has opened doors I would not have thought possible. You inspire me. Congratulations on another trip around the sun; I am looking forward to the next annual trip together again.

Sand Sand Sand

Why say it 3 times? Well, I spent 3 days sanding all the orange peel off Zed's exterior. After trying a few different grit combinations to get the orange peel off, I found wet sanding with 120 grit and following with 320 (also wet) removed the orange peel most effectively. This was not fast, however. I put in 3 6-hour days to get the orange peel gone. Fortunately, I had put 3 coats of base on, so I didn't burn through to primer very much. I still have almost an entire gallon of base, so when I have another full day available (maybe next weekend), I can shoot 2 new coats of base and then the clear.

Even after a wet sand, there is a residue. I washed everything with a mild no-residue-leaving car wash and the garden hose. With our warm dry weather, the puddles dried up quickly. I will still need to do my usual de-grease, tack-cloth routine, but I am starting out from a much better place than had I not washed it. 

Bumper Installs
front p-side
With the car sanded and clean, I decided to install the bumpers. If I learned anything from the side skirt installs it is that they will not go on effortlessly. Had I shot the pain perfectly, I would still probably have something to fix with regards to the bumpers after installing them. Unlike the side skirts, though, they were not nearly as non-compliant.

My method was similar. I started with a nice coating of contact cement on both the inside of the bumper and the steel bar it was attaching to. Ditto for the side panels. Once the cement was set up, I applied some of the clear epoxy on top of the cement along the top and face of the bumper bar. I then set the bumper in place. For the rear bumper, I re-used the M4 bolts to hold it in the right spot as the cement and epoxy set. I held the front bumper in place with a pair of long clamps just in front of the front wheels. To make sure the front held well, I spread a thin layer along the top seam, like I had with the side skirts. I know I know... this stuff is "sandable" (read: not really sandable), and I'll be scraping boogers before I can shoot the paint. I am willing to accept that, if the bumper holds firm. In the picture below, of the driver side, you can see the seam marked with a shiny line. That will need to be minimized for paint.

front d-side
The next morning, I tested the hold. I could lift the rear end of the car by holding onto the bottom of the rear bumper. That's a win. For the front, I removed the clamps, and pulled the bottom edges (near the tires) away from the car. The fender flexed a little bit, but the bumper did not budge. I will be scraping boogers, but it will hold.

Well, that's basically it for today. It has been a very labor-intense week for such a short post. That's how it goes some times, though: work for almost 40 hours and have little to show for it. If the weather holds ,and I can carve out the time, I hope to be shooting this weekend.

Zed Body Kit Start

Last Summer, amid the economic restart following the CoViD-19 shutdowns, I ordered and received a fiberglass bodykit for a Datsun 280ZX. It arrived too late to be wrapped into the body work, and I ran out of warm weather anyway. Today, I restart the body work on Zed (1979 Datsun 280ZX), with hopes for having Zed painted before I run out of summer this year. Even though there is considerable Summer left, my time is less available this year than in years past. Boo has injured her arm/shoulder, preventing her from moving it per Dr orders, so I am doing a lot more not-car stuff these days (read: lawn care, housework, etc) which all take precious minutes. 

Back to Start
bumper gap set
While Zed was parked under a canopy / car port all winter, that is not the same as sitting in a climate-controlled garage. Or even an unheated garage. Rain does not fall straight down, and wind blows organic material around. So, when I was ready to focus on Zed, I had a few steps to just get him back to where I had left him last Summer. I had been using his interior as a staging area for parts and boxes while working on the sound/noise contain effort in Hapy (1972 VW camperbus). So, logically, the first thing to do was to vacate the interior and shop-vac it out.

Next, the body panels needed a cleaning. Rather than use a hose, I hand washed him with a bucket and scrubber sponge. Still, I was unable to free some of the green haze that had appeared. He would need a sanding in order for the next layer of paint to adhere anyway, so I left what remained to be addressed by the sanding. I pulled out the body kit that had been stashed inside and cleaned it too.

Front Fenders
d-side bumper
I had spent some time wrangling the front bumper last Summer. I could only get so far because I had not completely solved for the fenders yet. Now that the driver fender was ready, I could move forward. I started by simply mounting the fenders with M6 stainless bolts. When I fastened the bottoms, the fenders ballooned out into their proper shape. I had not realized how flat they had been sitting until then.

Rear Bumper
The rear bumper was the closest to being complete, and after spending so much time on just getting things back to the way I thought they were, I wanted a win. I started fiddling with it and I discovered that I had not really prepared the steel rear bumper hidden within: it had rust spots on it and it was still dirty from when I bought it. More cleaning with a bucket and a scrubber and then sanding, rust treatment and a shot of Rustoleum got it ready enough for use. No, I don't really like the idea of Rustoleum on this project anymore than I think you do, but this will protect the bumper well enough, and once I sand a key into it for the epoxy to grip into, the paint choice really won't matter much anymore. After the paint cured (or 48 hours later...), I re-attached the bumper, making sure the height was completely flat, with the same distance between the tail body panel and the top of the bumper. It is into things like this that so much time is lost. Bolting on a bumper takes, like 10 minutes. Getting it exactly height-right, took more like 30.

p-side bumper
Once the steel bumper was set, I returned the fiberglass bumper to position to get it exactly where I wanted it. After some time spent fiddling with it, I was able to set the bumper such that the gap is the same across the rear, from corner to corner, and the seams along the rear quarter panel were consistent as well. I drilled a hole inside each wheel well near the top of the bumper and set it for good with a pair of M4 bolts. With the height set, I set the spread (tilt in or tilt out of the bottom of the bumper) of the lower edge. I controlled this with a second set of holes lower in the panels. Again, I set 2 M4 bolts through the bumper into the rear wheel well. I may eliminate some of these bolts later, after the epoxy sets.

Side Skirts
setting the spread
With the rear bumper looking good, I shifted forward to the little skirtings that run under the doors. I was not 100% convinced these were necessary when I bought the kit, but now that I have them roughed in, I like them. These kits are one-size-fits-none. While that was not really true with the rear bumper, it was definitely true with these side skirts. The length is quite good, and the fit into the wheel wells was almost perfect. I say almost, because I had to cut a small chunk out of the top of the passenger side skirt for it to fit. The issue with these skirts is with the little lip that runs the length of the door jam. These are designed to sit on the outermost edge of the door threshold, but the design has 2 problems. First, the lip is fairly thick so the door does not easily close on top of it, if the door is set at the right height. Second, and perhaps more important, the lip is not at the correct angle from the outer edge of the skirting. So, if you set it in place on that outermost edge, either it is in the right spot, but completely blocks the door -or- the whole skirting curls under the car too much, not aligning with the fender lines and looking horrible. I resolved by cutting off the lip with a hacksaw. Yes, that is a rather destructive move. I considered all the plastic panels on the ToyoTruck and the panels that run under the doors do not have a lip hanging on the door sill. These will now be a same.

fun with Bondo
With the lip removed, I was better able to control the angles. Similar to how I managed the rear bumper, I first set the height by getting the under-the-door edge just a smidge below the door opening. I set the height temporarily with clamps and then bored holes, used more M4 bolts to hold the tops in place.  I added a bolt on each side, near the leading edge of the door, to hold the section of the skirting which will attach to the front fender in place. I will use this bolt for setting the epoxy, but will remove it, or cut the head off, after the epoxy sets. Next, I set the spread so the rear outer edges aligned with the rear bumper lower leading edges. Because of how the skirts were constructed, this left a small gap at the top rear of the skirt. If I pressed the top against the side of the car, the bottom of the skirt would stick out too far. The picture below shows how it lined up. Because of the curve of the body, it is not immediately visually clear that the bottoms align, but they do. 

Body Fill the Gaps
d-side skirt rear
Around the internet, Bondo is a four-letter word. No one admits to using it, but practically everyone does in some capacity. If I were a master fiberglass guy and had all the time in the world, I might have built-up the trailing edges of the side skirts with fiberglass. That would have been the "right" way to do it. I don't have that skill, nor the materials, and, like I indicated at the top, I really don't have that time. So, I chose Bondo, and went full-on ShadeTree with it.

I have the panels attached exactly where I want them, held on with bolts. I don't want to remove them apply some material grind some down, re-attach, wash-rinse-repeat, in hopes of getting it right. That could take all Summer and still might not look that great. I want to apply filler to the fiberglass but not create a Bondo-bond with the side of the car. To resolve, I grabbed some non-stick spray from my kitchen and shot the steel body panels where I needed to fill a gap. I then cleaned the fiberglass with oil/grease cleanser, leaving the non-stick on the steel and I filled the gaps with Bondo. Is this how a pro would do it? I sincerely doubt it. Did it work? It worked well enough to define the lines. Once teh Bondo set up, I freed the panels, leaving them loosely attached. There was not any Bondo stick to the steel. I sanded things smooth and did another pass to get the seams really clean. Last summer, I tried to resolve the don't-stick by taping plastic to the steel, but no matter how well I set the plastic, there were minute folds which appeared in the dried Bondo. The non-stick spray left a predictably smooth line.

Sanding
body sanding fun
I re-attached the rear bumper and the side skirts after sanding the Bondo smooth. Then, I set into sanding the entire car with 320-grit. As I mentioned above, simply cleaning the body was not enough. Besides, I chose to not sand the primer last year, believing it would better protect the paint over the winter. It needed to be sanded before the next coat, be it more primer or color. I will be priming the fiberglass body panels anyway, so I may shoot primer on the rest. I'll decide that later.

I am about 2/3 done with the sanding of the whole body (fiberglass and steel), working from the rear forward. Once the sanding is complete, I will be setting the height of the front bumper ends, and perfecting the front bumper seams like I did with the rear bumper and side skirts. After all that, the fiberglass will be removed one last time for priming.

That's it for today. Thanks, as always, for following along-

Zed's Slow Crawl into Fall

It's time for another update on the slow-moving restoration effort on the 1979 Datsun 280ZX lovingly called "Zed". Completely unrelated to Zed, Nemo, the 1997 Audi A4 was sold to a family friend. While he is no longer a permanent resident of our driveway, I expect there will be some ShadeTree adventures as he is improved upon.

Where Were We
p-side front fender gap
We entered the Summer with the goal of having Zed painted before the weather changed from warm-dry to cold-wet. Some years, that change happens as late as Halloween. Other years, like 2019, we lose the end of August to things like wildfires or an early rainstorm. With such a wide range for when the end date might hit, I worked a bunch in the early Summer to set myself up for paint. This year, we have had multiple "false-fall" weather periods, and this week looks like solid rain, leading me to believe that the goal will not be reached.

Recall, we hit a snag with CoViD-19 related manufacturing delays on the body kit. I ordered the kit in May, and it delivered in August. During the delay, I perfected the body as best I could, got the final primer shot and clowned on other cars while I waited. Once the kit arrived, I let it sit in the sun on my deck for a couple of weeks to complete the off-gassing while I took a few camping trips. Of course, sitting outside like that allowed the various pieces to get dirty and have nature fall on then, so they are not as pristine-looking as they were on delivery day. Regardless, they need to be sanded, and primed at minimum before painting, so this just added a cleaning step before the sanding.

Front Bumper
d-side front fender gap
To prepare for the front fiberglass bumper install, I first needed to expose the steel bar wrapped inside the chrome and rubber bumper originally installed on Zed. I had removed the bumper, brackets and all, earlier for access to the radiator supports for primer shooting. The bracket-to-body bolts are 17mm, and there are 4 per side. The bracket-to-bumper nuts are 14mm, and, again, there are 4 per side. I addressed the surface rust on the brackets, shot them with the same finish primer and set them aside.

The original / stock bumper cover is held on with a myriad of bolts and screws. The (10mm?) bolts removed easily. The screws were so rusted on, I had to cut them off with a grinder. Once the steel bar was exposed, I could start test fitting the bumper. I spent a while just fiddling with it: setting it on, tilting it at various angles, etc until I could see how I wanted it. I temporarily mounted the front bumper brackets and the steel bar next, and sat the bumper cover on top. The original location of the bar was 1.5" too far forward.

To recess the front bumper, the gas in the mounts needs to be released, and then the bracket pushed backwards into itself. To release the gas, the steel bar needs to be removed and then a Phillips bolt head is exposed. Remove the bolt, and the gas is released. Then, push the end in. I measured the 1.5" and marked it so I knew when I had it in the right spot. At first, the brackets did not want to compress, even with the gas gone. I encouraged them with a rubber mallet and pushed until the bracket compressed to my mark.

Once compressed, I re-attached the steel bar, and then set the new bumper cover on the bar. This time, it set exactly right, though the ends initially appeared much wider than the fenders want to sit (witness the top two pictures). After about an hour of fiddling with it I found that when the ends of the fender rotated upwards (and the fiberglass shifted left-right a little bit, the steel bar readjusted, etc), they were much closer. Still, actual mounting to the fenders will wait until I have the fenders secured firmly. The fender bolts, like most of the others, have disappeared. The internet thinks these bolts should be M6x1, but I could not even start threading that size. They are also not M5x.8 as those fall right through. I tried generic slotted #12-24 machine bolts next since they are effectively "M5.5", though they also fell straight through. I will return to the M6 bolts and see if I just gunked up the threads with primer. Anyway, with the bumper in place, I can see that I will need to open up the turn signal indicator holes a little bit to allow for the lenses and bulbs to be maintained without removing the bumper. Also, I expect there will be some shaping needed where the hood opens since the bumper is 1.5" deeper.

Rear Bumper
The original rear bumper was the only real rust on this car, which is why we tossed it. I sourced a replacement bar and rear mounts from our friend in Hillsboro. After addressing the surface rust on the brackets similar to the front brackets, I acquired nuts to mount the brackets to the rear (M10x1.25) and attached them. I needed a washer between each of the outer holes on the mounts and the body to angle the mounts inward enough to fit the rear bumper. Onto the brackets, I set the steel bar and test fit the rear bumper. Again, the bracket pushed the bumper out too far to fit. So, I repeated the gas-out process, pushing the rear bumper in an inch. Unlike the front, the rear bumper does not provide an easy means of getting your fingers on the mounting nuts and studs. But, with some perseverance, I got one nut on each side so I could see how it set. As good as the front looked, the rear looked even better. The kit snugged into the body contours, as you can see in the picture below.

Setting the Gaps
p-side rear alignment
When C bought this car, it had been messed up by the prior owner in 2 ways. First, he stripped the interior in the interest of saving a few pounds because he wanted a drift car. Second, he drifted the car into something or someone, damaging the driver door and front fender. We replaced the front door with a donor from WA, but tried to straighten the fender. Off the car after many days of working on it, the fender looked great. Once I re-mounted the doors, hood and rear tailgate, however, the gap between the leading edge of the driver door and the trailing edge of the fender could not be resolved. The edge along the front valence (in front of the windscreen) and above the door also did not line up well. The fold in the driver-side fender had erased the trailing edge and attempts to re-establish it by my amateur hands did not get it there. The image below shows how far off the fender-to-door gap is; the misaligned edge above the door is slightly visible. The passenger side, however, gapped perfectly, with about 1/4" along all of the seams of both the door and the fender so I have a target for the driver side. I spent a couple of hours shifting the door around and improved the gap at the top, but the long edge between the fender and the door could not be resolved. I did not reproduce that edge on the fender quite right.

The efforts to straighten the driver fender has been instructive, but, I will be replacing it. Unfortunately, these panels have not been produced in years, so I needed to find one from a donor car and the one I found is not dent-free. Fortunately, the edges are perfect and it aligns properly with the hood, bumper and driver door. So, once the dents above the wheel well are coerced back into place, the panels will be right. I will then set the driver-side gaps so we have a solid base for the kit. Then, I'll finalize the placement of the bumpers.

Bumper Plan
Both the front and the rear bumper will require a little bit of fit and finish. The rear aligns very well, with only some small smoothing needed to achieve the line I am looking for. The front may require more, even after the fender fit has improved, the gaps are larger. I will see how much this gap closes once I send a couple of screws through. I expect I will need to add material to the inner edges of the bumper along the fenders to make it look right. Once I have the front and rear looking as I would like, I will shift to the two side panels that run under the doors between the wheel wells and then priming the kit.

I do not intend to seal the seams between the fender/quarter panels and the front/rear bumpers. Instead, I intend to have a clean, visible, seam line. This way if there is some kind of damage to the fiberglass from parking curbs or a small accident, the repair will not have to extend past that seal line. This also gives me the opportunity to try mixing flex additive into the fiberglass bumper paint. The "flex additive" increases the paint's willingness to bend without cracking. If I sealed the seam and painted the body as a whole, that flexing additive would need to be part of the paint on the seal or further up fender/quarter panel paint. Otherwise, there could be cracking at the seam, forcing the repair into the steel. This way, the bumper can be removed, repaired/replaced, painted and installed.

What's Next
The ultimate question remains: will the car get through paint before the weather changes? No, but I would rather have it look right than be hurriedly finished. First, I need to get the driver fender replacement undented and prepped. Then, I will get the body kit fitting completed with mounting holes drilled, etc. This would allow me to finish the kit separately (clean, sand, Bondo, sand, clean, possibly high-build primer, sand, clean, finish primer, sand, clean, paint) and then mount it when it's ready. I don't expect a weather miracle that would allow me to get all the way to the end of that task list, though. I expect the weather will turn for good before I'm through primer. Actual paint on the body and the kit will have to wait until next year.

Zed Body Progress

With the weather shifting warm to cold to warm again, Zed (the 1979 280ZX) work has been a little bit on-again / off-again. With the weather returning to hot for what looks like the Summer, I shifted efforts back to Zed from the other projects (you've seen the posts)... well, until this past weekend when everything came to a complete stop due to the record-setting high temps (over 45*C / 113*F). Today's post focuses on Zed's body work again, solving for the missing rear bumper and getting after some priming. Again.

Bumpity Bump
A lingering question for Zed was how to solve for the rear bumper. The original was a rusted out mess, and donorZed was about as bad. I was considering how to construct something one-off custom, but decided that an off-the-shelf fiberglass kit was a better looking, and fastest-to-implement approach. Rather than just do the rear, I got a full kit, so the front-to-back is consistent. Of course, this will delay the paint a little bit, as I have more body panels to solve for. Plus there is the added delay introduced by shipping. Ultimately, Zed will look better, so it's worth it. The kit I ordered looks like the one pictured on the side here, without the big wing on the back. That's not my style, but everyone gets an opinion. Later, I will add louvers to the rear window since that window lets in a ton of heat in the summertime if left uncovered.

In order for the rear fiberglass to mount, I needed the rear bumper bar that sits inside the big rubber ugly. I reconnected with the local Z parts-hoarding-guy to whom we sold donorZed and bought a rear bumper bar, and mounts... for about 1/2 what we sold the entire donorZed to him for. Funny how this all works. Perhaps, in retrospect, I might have saved the original rubber bumper support bar and mounts. Anyway, next was clearing the rust off the bumper mounts, and getting them ready for action. I used multiple passes with Naval Jelly followed by a coat of Eastwood Rust Encapsulator and then a coat of rattle can primer. I will shoot these with the hinges and other tiny bits that we want the color of the finished body.

Following that, I removed the front bumper support (4 16mm bolts each side) and the bumper from the supports (4 14mm nuts each side). Next, I wanted to remove the rubber ugly wrapped around the bar so we were ready for when the fiberglass kit arrives. The Phillips screws that hold the ugly cover on, however, were rust-locked in place. Multiple passes with the Kroil didn't allow them to budge. So, I had to grind them off. It is interesting how much rust was on the bumpers and how little the rest of the car had. Those front bumper mounts had virtually no surface rust on them while the bumper itself had been impacted. These mounts will also get the color spray with the other bits I mentioned above.

Prime Time
Last, I finished enough of the Bondo cycle to feel that I could lay another round of hi-build primer. The Bondo-cycle took an awfully long time, and I got far too into it. I imagine I still missed a bunch of things and it still will not look as good as a real pro paint job, but at some point you just have to stop dicking with it and go. Otherwise, you will never get to enjoy the fruit of your labor. It's just labor. I am enjoying the heck out of bodywork though, which I kind of surprising. My first round of high-build primer was both too light and mostly sanded off so if you are concerned that there will be this huge stack of paint layers, rest assured, that is not happening. I did have to wait for the weather to get warm and dry enough, though.

Once the weather turned warm again, I acted like the primer had not happened before: restoring the masking, vacuuming and blowing air, cleaning the snot out of it, etc. so it was ready to get primed. Then, I laid the body panels out under the car-port cover again and repeated the multi-passes of primer, just like I did last Fall (See Zed Prime), with a few differences. My set-up this time did not include the in-line line drier nor extra pressure regulator. I had not gotten another disposable line-drier, and without it, I could not attach the regulator. So, I set up my pressure with test fan blows on one of the fenders instead. Total Roadkill. I figured I could reduce the moisture if I kept the air compressor tank warm, so I moved it into the sun. Since the air around here is super-dry right now (humidity below 30%), there isn't much moisture in the air to get compressed into the air line anyway. This may sound sketch, but the primer landed fine.

As to shooting, I did a light first coat to give subsequent coats something to adhere to, while also avoiding runs or sags. The sunlight was so bright, it was hard to really see the fan, since the color of the primer was the same as the target panel most of the time. Similar to the 1st shoot, I did not meaningfully stop between coats 1 and 2: fill the cup, shoot the cup, repeat. Why? Because, by the time I got all the way to the end of the light coat, the place where I had started had sat for longer than the minimal flash-dry period, and it was warm enough to dry fairly quickly. The surfaces were tacky when I went around for my heavy pass, which, I felt, was just right.

The 2mm tipped gun got clogged about halfway through my 2nd coat. As I attempted to unclog it, I lost about half of a shooting-cup (or about an actual imperial cup) of paint: it turned to Jello. I think I mis-measured the concentration of hardener. Could it have been from the lack of an air-drier? I dunno. Undaunted, I grabbed another gun which had not been drilled out to 2mm; it was a 1.8mm tip. I did not clean it first, I just blew a few seconds of primer through it and got back to the job. Yes, that was lazy and yes it could have allowed for some shipping oil/crud into the primer. I considered all this and used the first little bit of shooting to second-coat the nose section that will be mostly hidden from view (under fenders, radiator support, eg). More Roadkill; maybe that show is a bad influence on me. Anyway, I finished the pieces I had not gotten with a 2nd coat after I shot some hidden areas. I found that the 1.8 tip flowed better, gave a smoother finish and had a more predictable fan than the 2mm drilled tip. So, I take from that either (a) I drilled the tip wrong or (b) my 21gal compressor, pressure set up, gun and material were all better suited as a unit to the 1.8mm tip. I'm not sure how you drill wrong, so I think the difference is really tied to my compressor, and it's ability to keep up with the air-pressure demand of the 2mm tip. Regardless, I will be shooting this high-build with the 1.8 tip on a very warm / hot day from now on.

Reviewing the Prime
None of these changes, including the especially Roadkill-inspired ones, appear to have made much of a negative impact on the primed surface. Quite the contrary, actually. I started setting up the first gun at 10 and finished spraying by 2. I took an hour to clean up work area and the second gun (first gun went into the garbage) as I let the panels sit for the rest of the afternoon. Late the following afternoon, after the panels had sat in unseasonably warm temps (30*C+ or 85*F+) most of the day, I did some test sanding on the mostly-hidden areas with some 320 grit paper. The primer powdered smooth very quickly. If this is any indication, then this priming session was much better than the first. Perhaps this high-build poly-primer is more temperature sensitive than the Eastwood folks indicated on their site: warmer drier days are much better. The first time around (when it got into the lower 50's*F/11*C overnight after shooting), there was meaningful stippling on the surface. This time, when the overnight temps barely got below 70*F, the surface is much less dimpled. And, it sands smooth much more easily; like, a few passes with 320 and it's smooth. Last Fall, I tried pre-warming the panels inside my garage but that had no effect: the shell which sat outside the whole time had the same little dots peppering the surface. I think the real difference was the long warm days both the day of and after shooting.

Learnings
My big take-aways from the shooting the hi-build poly-primer from Eastwood: use a 1.8 tip and an in-line drier on a warm-to-hot day when the overnight temp will not fall below 18*C or 65*F for best results. Do a quick-coat first for the next heavier coat(s) to adhere to. Last, it is a good idea to have an extra gun as an emergency fall back in case you mess up the hardener concentration and jack up your gun in the middle of your spray-sesh.

Go Forward
Next, I will be sanding the rest of the body panels. Then, once it arrives, I will be handling the body kit. At some point, there will be paint, but I may shoot a urethane primer/sealer first (once Eastwood has it in stock and ships it to me). And, of course, the body kit will probably need some tweaks and then priming. I sincerely hope I can get it all done before the weather prevents it. While the Fall rainy season is a distance away, we cannot guess whether we will be revisited by toxic smoke again, scrapping late-Summer plans. For that matter, we are having triple-digit heat waves (40*C+) that are keeping me penned inside as effectively as the smoke did last summer. 

I expect that if I have to wait too long for the body kit, I will set up and shoot the parts that will not be impacted (like the underside of the hood, the hinges, the bumper mounts, etc) so I can make some headway and save myself some shooting time later while also getting a better feel for the equipment and material. Some of this stuff may not be terribly post-able, but I will try to at least put a little message here about the work.

Zed, Block Party of 1

Brief post today. After completing the various projects on Hapy (1972 VW bus) and Oliver (1978 MGB), I decided the weather was starting to look promising for getting back after the paint on Zed. Today's short post is re-entering the world of body work.

Where Were We
Last Autumn, I seized an unseasonably warm dry day after rainy season had started to shoot some hi-build primer onto the shell and other removed body pieces. I thought this was the best way to protect the largest portions of the exposed steel from rust. My thought appears to have been spot-on, and the shell appears to have fared quite well. Consider that the shell sat outside all winter under a temporary car port.... until February when we were hit with an incredible ice storm. Power was out across the Portland area for days. I did not lose power, but Boo and I had to go out into it to save the cars parked under the car ports. The ice had been building up, and you could see the material starting to flex. So, we pulled the opaque plastic sheeting off the frames and instead covered Zed with a pair on regular tarps. I knew this would encourage moisture to gather underneath, especially as the ice melted away, but I feared leaving the primer exposed to the elements more. The car ports were restored and the tarps removed within a few days.

Assessing, Sanding and Re-Priming
even under the fenders
Now, months later, our weather is considerably more suited to outdoor play. With various grit's of sandpaper, I started sanding the primer, and looking for rust. I was pleasantly surprised to find very little. Before I could really get started, though, I spent some time cleaning Zed, and vacuuming everywhere with the shop vac.

I started with the front clip (valence in front of the windshield and the exposed sections which will be covered by the front fenders. There were no new rust spots, but the sanding took most of a day. I took the hi-build down as smooth as I could with 150-grit first. The primer was so rough, it took the sandpaper down fairly quickly. Once smooth-ish, I would shop-vac all of the dust and wet sand with progressively higher "grit", starting with 220 and finishing with 400. Once smooth, I cleaned the area with oil and grease remover and then shot the area with self-etching primer.

halfway around
Once my process was defined, I spent the rest of the weekend, and the next week (around my work schedule) working my way around the rest of the shell. Overall, the body withstood last winter's weather very well. Of course, there were many places where I sanded through the hi-build primer down to the bare metal again. I found a few (less than 5) surface rust spots that I needed to sand down to bare metal as well. Still, the overall condition was quite good.

And Then More Sanding
Once the shell was completed, I shifted to all the other body panels (2 doors, the rear tailgate and the massive hood). Those parts represent more than half of the entire car surface area, so I expected that I would be sanding for quite some time. I did find, however, that using a block did move the sanding much faster, but the block can also accelerate you through the primer. So, I am using a mix of the block through the larger flat areas, leaving the edges for doing by hand, or much more slowly with the block. This balance has been working. Also, I only dry-sanded, focusing on 220-grit with a quick pass with 400 (again, dry), out of concern that the hi-build primer would absorb water.

More Bondo? Why, Yes, Thank You
there are always more spots
The shell that sat outside all winter needed better priming, but the body panels that were stored inside all winter needed more body filler. I had thought the hi-build would help cover up more of my bodywork misses. Nope. So, once I got the hi-build down smooth, I went hunting for waves in the panels. I found a few, and returned to the Bondo-Sand-Bondo cycle (See Bondo Zed) . I do want to stress that at no point is the filler more than 1/8" thick; I have 1 of 2 issues continuing to appear: over-sand or under-apply. In either case, the result is a need to go at it again. Fun. Eventually, I will have the panels in a condition where my hand cannot feel wobbles in the panel and then I'll be done. At that point, I will re-shoot with the hi-build over the Bondo spots as well as re-shoot on top of the self-etch on the main shell (this will insure better paint adherence). And then, of course, sand where I shot. Whee!

That's really all there is to talk about. I expect there will be a break in posts unless I take a step away from Zed to do something small on one of the other cars or take a trip or something. So, if you don't see a post, you know why. Once Zed is genuinely ready for final paint prep, there will be a new story to tell, and I'll post on that. Whether we are celebrating US Independence Day or Hapy's 50th birthday before that... well... Let's See. I have discovered along the way that we are missing the front air dam thing that goes under the front bumper. And, I don't have a solution for the rear bumper yet, so I'll be thinking about how to fill those gaps in an interesting way as well. If the solution will require painting to body color (likely), then the actual application of top coat may move further into the future. Cool.
