Floors and Door

Today, I am continuing the ongoing efforts on the NewOld house, that farmhouse around the way that Boo bought. Similar to the Creepy Crawl Space, we hired for skill for the floors. So, this post is really just before and after shots. We also replaced the front door. Something that relatively insignificant didn't really warrant it's own post, so I tacked it onto the end of this one.

Clean
cleaning
I regret that I do not have pictures of the floor before we got the house. We saw them and they were scary. Once the place was fully vacated, we could see what we were up against. There were historic pet stains. There was water damage. There were sticky spots, discoloration, kitty litter dust and general filth throughout. So, while Boo was cleaning the kitchen and bathroom for the second time (the first was while I was power-washing the outside), I took a first run at mopping the floors. I found that I was able to rinse the mop two or three times before the water was gray and needing changing. So, I started nearest the water source to shorten my trips. I spent a few hours doing this, and never really got the water to stay mostly clear for more than a few rounds with the mop.

Once the overall mopping appeared to be becoming fruitless, Boo switched to focusing on the worst spots first. This improved the spaces, but, again, there was a lot of floor, and simply getting them cleaner was not going to make them good enough. We needed them to be sanded and clear-coated. This is not a skill I have, nor is it one I want to learn on a floor I intend to see every day. So, we hired the guy who did the floors in the house we're currently in.

Sand and Stain
sanded
Thomas and his crew arrived on a Monday. By the middle of the afternoon, all of the quarter round was removed, the plastic was up to seal off the kitchen and half of the floors had already been sanded. It really makes sense to pay for others' expertise on some things, and, in my opinion, this is one of them. They hit the main floors with an upright belt sander, and did the tighter areas by hand. Once sanded, they vacuumed the entire floor and them applied a thin veneer of putty to fill the imperfections and fill the seams between the boards. The next day, the putty was dry, so they hit the floor with a sander again, vacuumed again and then applied a stain. Why a stain? Well, even after sanding there were some stains that just would not come out. Some of the animal waste and water stains were too deep. By using a uniform darker stain, those inconsistencies disappeared. Our current house is very dark in the winter, so we were really hoping to not have dark floors, but the alternative would be an inconsistent "distressed" look which might look interesting, but may not appeal long term.

Cleared
stained
After letting the stain sit for 2 days, they returned to apply the high gloss clear coat. This is applied with what looks like a long, thin, flat mop. The resulting coating stands up to animal claws, dragged furniture, etc.. all within reason, and has a brilliant shine to it. Boo and I were not thrilled with a darker stain, bit the high gloss may help offset the darkness.

Close the Front Door
When we acquired the house, it was apparent that someone busted the deadbolt on the original / existing front door. The door frame was damaged to the point where a good shove with your shoulder would open the locked door. The existing door was effectively a "contractor grade" door intended to be the door during construction that is later replaced with a fancy door. Back when I painted houses, the reason for this was obvious: we sub-contractors banged into everything, especially if it was nice. It's not like we looked for that stuff, it was just always right in the way.. like the front door. So, one of the last things done before handing the house over to the owners is to hang the fancy front door. Unless they didn't buy one, in which case the construction door remained. Such is the case here. 

Anyway, We hit the Habitat for Humanity rebuilding center and bought a replacement pre-hung used solid wood front door for $65US. It is not perfect in that it does not close perfectly, but it will keep the bad guys out when locked, and it hangs level so it will not swing open or shut without someone moving it. The upper leading corner (the end with the handle, not the hinge) and lower leading corner do not sit all the way into the frame, so we will need some thin foam in the door jam to keep the wind out. Or we may need to fiddle with the middle section so that sits deeper in the frame to help seal the edges. Regardless, it is a much nicer looking door and it locks.

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

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-

Around the Rim (Part 5)

I really can't believe it took 5 posts to cover cleaning up and painting a set of rims. It took fewer posts to cover replacing the floors. I guess there were more steps on the rims. I can't believe it took longer, calendar-wise either, but getting things done in the cold winter is much harder than getting them done in the warm summer. I should probably remember that when I plan things. It could be at least in part because most of the rim work has been done outside since the garage is full of project cars and assorted parts and painting in cold weather forces some creative thinking. Hmm... anyway.. on to the paint!

Prime and Sand
Once everywhere you don't want paint is covered, you're ready to prime. By "everywhere", this includes the rubber tires, and the inside of the rim. If I had a paint gun, I would have gone that route, but I don't. So, I did the best I could with what I had: rattle-can primer, paint and clear. After all the time I'd put in the prep, I really wish I could have used a real paint set-up, but that's just how it goes. Follow the directions on the paint. Use many light passes with the primer. Make sure all of the deep spots (like the holes where the lug nuts go) get hit before going after the easy spots.

Once dry, let it set for an extra stretch of time. I let them sit for a weekend in a warm dry room, but I'm just like that. Using 320-grit sandpaper, I smoothed out the primer on all 4 wheels. I expect some would prefer to sand with even higher grit paper, and if this were going to be a 6-digit car, I'd defer. I expect to drive this car, not show it. The road will wear the rims no better nor worse if I sanded more. Anyway, similar to the treatment before taping, I wiped the wheels down with glass cleaner after the sanding was completed.

Color Up
First, I wanted a body-color matching edge. I've been looking specifically at rims on cars almost as long as I have been looking at cars. Where having one-color rims was the only way for years, a blending of shiny alloy and color is becoming much more common. I waned to go one more step and do 2 colors plus alloy. So, I started with the body-color match. This brings the rims to the car, helping bridge a gap created by not going with a common rim for the MGB (Rostyle or wire).

To do the color, I first tried to mask off the rest of the rim using thin-wall cardboard, but I could not get tape to stick to the old primer-covered tape. So, I dug back into my old house-painting bag of tricks and cut a make-shift paint shield out of a pizza box. By holding the shield up along the side, but not touching any to-be-painted area (against tape), I was able to deflect any over-spray without getting the cardboard into the fresh paint.

The weather here has been cold and wet. Neither of those conditions are good for painting. To offset some of the bad, I kept the rims inside my living room up to the moment I was going to apply paint. When there was a break in the rain, I quickly moved a room-temperature rim out into the yard, popped it onto an upside-down 5-gallon tub and shot color. Two times around for solid coverage and then I set the rim flat under the front porch eave and ran inside for another rim. I did this until all 4 rims had a vermilion ring.

Black Out
About this time, we were hit with successive snow storms that delayed my progress a bit. That's why the 4 different parts of this post didn't come out one right after the other. Anyway, once the vermilion dried and set for a few days in my semi-warm garage, I planned for the black paint. Before I could shoot the black, I had to cover up the vermilion, remembering that tape wouldn't stick well to primer. By contrast, the painter tape stuck very well to the orangey finish-color. As gently as I could, I covered the orange ring. I discovered while striping the tape that some spots were soft and the paint pulled away with the tape. I chalk that up to the cold conditions and did some isolated touch up.

Anyway, once the orange was protected, I shot the exposed rim with a reasonable coat of black primer, sanded (600-grit) and then shot hi-gloss black. I intended to do two light coats with the high gloss, but between the weather conditions and the paint, I couldn't get a light coat to lay down. So, I did a heavier-than-I-intended coat and then quickly followed with a light coat on top of that. The end result was pretty good, leaving only a couple of sags. I caught them early enough that I was able to scrape them away and re-shoot. A few marks were left behind, but they disappeared during color-sanding.

Color Sand
After I shot the black and let it set a couple of days, I pulled the tape off the orange. It looked pretty good, with a couple spots I knew I'd need to address. I opted to get the wet-sanding done first, and grabbed a bucket of warm water and 1000 grit paper. I cut the paper into 2" squares and wet-sanded each rim with a fresh square, rinsing the paper in the bucket every minute or less. This took down the gloss, but also removed little paint anomalies. I also wet-sanded the vermilion. I had virtually no burn through, with a few little spots near the lug holes. I simply covered around them and fogged-in some black and let that set for another couple of days before color-sanding those areas.

Strip and Final Prep
Once color sanded, I could remove all of the tape and get a good sense of how the final product would look. I knew there would be some clean up needed. Some tape had pulled away from the aluminum, so some paint made it past. Elsewhere, the tape wasn't at the exact edge, so some clean-up was needed. This took a few hours, but the result is better than I'd expected. To remove the over-spray, I used 220-grit paper on the raw aluminum. To set the fine edge, I used a putty knife along the contour to mark the line from black to raw aluminum and then sanded the rest of the paint on the aluminum side with the 22-grit. Once it was all sanded, I hosed it off, cleaned them with glass cleaner and then hosed them off again.

In the Clear
The funny thing about paint is that you find every little minor defect after you've applied it. I spent a few hours just nick picking on the paint edges and still they weren't perfect. I decided it didn't matter and I was pushing it too far. These rims were $100 with barely-serviceable rubber on them. They had deep gouges and the clear coat was flaked. I decided to just shoot the clear and be done with them knowing full well that the more time I put into them the more heartbroken I would be when the inevitable piece of gravel scratched one.

Once I had the rims cleaned, I moved them into my living room (thanks for your tolerance, Boo) so I could get them up to room temperature. Remember, it's in the 40F's during the day and getting below freezing at night, so getting the paint to adhere is a concern. So, I had an afternoon when it wasn't actively raining, so I followed the same process as before: one rim at a time, I bring a rim out, set it on an upside-down 5-gallon bucket and shoot. I was able to get a light coat of clear to lay down, so I followed the suggestions on the interweb (as well as on the can) and shot 2 light coats within 10 minutes of each other on all 4 rims. Then I moved them under cover and set them flat to dry.

The picture to the right, here, was taken the following morning, after it had completely dried. They aren't perfect, but I think they look really good. The concept of a 2-color plus chrome was executed, and once the tape came off the rubber, and they were mounted on a car, I think they look pretty amazing.



So, that's it for the Rim Job. I had a morning of swapping rims around the cars in the yard, but it was totally worth seeing the car transform. I think the next big effort will be addressing the radiator in the bus. I did promise Hapy that I'd replace his rad before the next festival season began. 4Peaks is less than 3 months away!

As always, thanks for following along-

2022-April-18 UPDATE:
It took me 4 years, but I finally found a set of center caps that fit these rims perfectly. Recall, these rims came from an early 90's Honda Accord, so you would think finding center caps would be relatively routine. It wasn't. I tried a "standard" set (69mm), but they did not fit (too loose). I had effectively given up, but I found a set of 70mm caps, and they fit perfectly. I had to tap them on with a rubber mallet, but they clicked in perfectly, and now look the business. I have not decided if I am going to adorn them with a sticker or something in the center. For now, I am leaving them as-is. Frankly, I do not intend to do one more thing on Oliver until he passes smog. Anyway, here's a picture with the new caps, but first, the sizing details:
  • 6 Clips
  • Outside diameter: 70 mm(approx 2 23/32 inch)
  • Backside clip to clip: 64.2 mm(approx 2 17/32 inch)
  • Sticker mounting diameter: 44.6 mm(approx 1 3/4 inch)
  • Clip Length: 10.7 mm(approx 13/32 inch)

Around the Rim (Part 3)

Today's post continues the saga of upgrading the rims on the '78 MGB from the crummy chromeys to some mid-90's Honda alloys.

Clean, Clean Again
original Honda rims
After 30 years of use, and very little in terms of care, these new-to-me rims needed some love. First, they needed to be cleaned. I started with some basic car wash, a scrub brush and a hose. This worked some, but there was some stubborn brake dust and other grime on the insides. This took brake cleaner and some 150-grit sandpaper, but I was able to get down to some silver. I washed them a third time, this time with dish soap and a scrubby sponge in my kitchen sink (Boo puts up with so much). Once cleaned up, we could really get a look at what I'd bought.

Assess the Damage
Two of the rims were in fairly good condition. There wasn't much in terns of curb rash around the outer edges, and there were only a few scrapes from what looked like applying snow chains. The other two rims, however, had been in a few fights. There were some small chunks chipped out nearest the rubber, and many many gouges in that outer edge as well. Sadly, there were some deeper wedge-shaped scrapes in the face where, again, it looked like the rubber strap for tire chains had been put on possibly wrong such that the loops dug into the rim.

Plan the Work
The damage, though, was purely cosmetic. I was able to add air, and the air held in all 4 tires. Since the damage was surface, I knew I could repair it, but I felt I would need to paint rather than restore to plain aluminum. I'm sure there are others out there who can repair aluminum such that it looks like the damage was never there. That's not me.

paint concept (upper right)
To fix the chips and gouges, I thought about brazing alumi-weld into the gouges, and then polishing. Alternatively, I could use Lab Metal. I've used that stuff before, and it really does finish nicely, but I'm not convinced that it will leave the exactly right color. I suppose I could mix aluminum dust from sanding the rim into the mix for coloring if I really wanted to retain the all-aluminum look. After looking at the rim on the car, I think adding some color would look better, especially since there is a very limited amount of chrome on the car.

So, I planned to repair the chips and gouges with Lab Metal, and paint the outer lip and the mag-face, leaving an inner rim and the insides of the mags the original aluminum. This would bring out some of the chrome while not having an overwhelming amount of it. I mocked up a few options in paint so I could get a sense of how it would look and then I got started. First, you need to get down to the bare aluminum.

Take off that Clear Coat
on-car paint concept
The Interweb is a great resource, but some advice just isn't that good. While some is wrong, other advice can just be ill-suited to either your skills or project. For example, there appear to be many folks advocating removing the factory clear coat by sanding until what you're removing shifts from white to grey. Then you know you're down to the aluminum. While this does work, it takes an incredible amount of time. If you try to short-cut the time by using a lower grit (like 60 instead of the recommended 100), the car part will get deeper gouges that need to be sanded off with higher grit. In the end, I'm not sure if much time gets saved. I tried this method with one wheel. Since clear coat is not applied uniformly, you will hit grey while also still removing coating. In the end, I think this method was a bust, and don't suggest it.

For the other 3 rims (and I came back and did the sanded rim too), I used airplane stripper. C had some from when he was stripping the paint off the 280ZX, so I knew it worked and worked well. At least on paint. I knew that it didn't damage rubber when little drips got on it. I laid out the three rims, and brushed stripper on one wheel at a time. Once I got done brushing the third rim, the first was about dry, so I applied a second coat. Doing all four wheels would have timed out just about perfectly. Once the second coat was dry, I attacked the rims with steel wool. The clear coating scrubbed right off, leaving the bare rim with little flecks of clear coat left behind. To get completely cleared, I used a razorblade scraper. The airplane stripper was significantly faster and left behind a better surface. I hosed the rims off, and they were ready for the next step: fixing the damage. I'll get into that next time.

Thanks, as always, for following along. More next time-
