Interior Carded

Once the headbanger was installed, getting the interior to a usable state was a downhill run. This post is really more a collection of all the little things that got done so we could hit the road. So, for today, "complete" means "good enough for this Summer"; it does not mean we're done. I will be picking this up once camping season comes to an end in October. Before I begin, Hapy Summer Solstice.

Cab Floor Complete

I had left some of the MLV splits un-taped. So, I started with that. I discovered that the Jute and MLV was too wide between the outer edges of the seat rails and the doors to allow them to close easily, so I trimmed them down. Then, the edges were taped down.

Sun Visors

sun visors in

One of the upsides to the new shelf was the potential addition of sun-visors. The visors that are on the market these days are not the same as the ones I removed; that could be a reflection of my old visors, however. These new ones are shaped differently, with a pop-out on the end that is designed to go behind / around the mirror, and the little stick on the end that is supposed to go into the little keeper near the mirror is therefore much shorter. So, if I was looking for a direct-replacement, these would NOT have fit properly, but, again, it is entirely possible that the PO installed bug visors or something way back when. The mounting base near the A-pillar is the same. I re-tapped the holes, knowing at least one, if not all of them, had metal screws instead of bolts at one time before. I threaded M4 Phillips bolts in to hold the visors. I attached the little keeper thing to the underside of the shelf. So, the visor, when not in use, tucks flat to the underside of the shelf. It turned out that the weird shape of the visor allowed it to almost wrap around the light fixture, looking like it was designed for that install. Sometimes, its just better to be lucky than good.

Cab Door Cards

cab cards nearly complete

Recall, my old door cards were falling apart cardboard. There's a cat in Arizona named Werksberg who makes door cards out of PVC, and I ordered a set last Fall (his TheSamba ad). Apparently, his costs are skyrocketing so if you want some of these and have been sitting on the fence, you might get priced out if you don't make a decision soon. Anyway, I was finally ready to install the fronts. Unlike the original cards which need to be installed with metal clips into little rubber boots, these cards deliver with small plastic molly's which press through the card into the original holes. They appear re-usable. We'll see. The driver door card is not staying put, even after adding double-sided tape so I may need to add screws.

When I removed the original-to-me cards, I removed the little door vent things. I set them in my trove of parts and did not install them when I put on the cardboard cards. I put them on this time. The door looks much more finished now, as you can see in the picture above-right, here. The rest of the card install is the same as original. The window crank removes / installs with a Phillips screwdriver. As does the chrome door latch mechanism and the door pull strap. Once installed, the door looks so much better than it did. I have not decided if I will apply the thin closed cell foam or not, but I am not doing it for now.

Kicks

partitions and mid-walls carded

The last thing I got after in the cab was the re-install of the kick panels. With the new flooring and 4-1/2" speakers, this was not as simple as before. Still, I found by setting the outer edge and then bending the card, I could get it pretty much where I wanted it. I pulled the jute and MLV up, allowing the card to sit on the floor. I could remove them, and cut off the lower 1/2" so they sit on top instead. Meh. Something to think about as we drive around this summer.

Slider Door

Moving rearward, I pulled the middle row seat out and the original-to-me slider door card. The slider had not gotten much treatment over the years, so it got CLD and 2 layers of Mega Zorbe. I thought the extra layer might reduce the racket when the door opens. It didn't at first. I spent some time with oil & grease cleaner working on the door runners, and that actually helped a little bit. The lower door roller is the source of the lion's share of the noise and noticed that the outer edge of the runner was a simple 1/4" tall thin bit of steel. So, I ran some leftover white "U" seal I had from doing the luggage rack to see if that would help. Nope. It effectively pressed the wheel against the inner steel track edge, causing it to make a different, but equally unpleasant, noise. I concluded the wheel was the noise-creator, and I ordered a replacement lower guide with a vinyl wheel, instead of steel.

rear tail gate carded

There are 2 bolts and one Allen-screw holding the guide to the door. The bolts on the old guide were so rusted, they broke off, leaving me with just an Allen-bolt holding the guide in place. I will periodically shoot those rusted bolts with penetrant, and when I am able to remove them, I will use M6 bolts in their place. I will apply anti-seize, though. With the new lower guide in, the door was quieter, and operated more smoothly, but the upper guide was making noticeable noise now. So, I removed it, and improved it with penetrating oil until the guide-wheel would easily spin between my fingers. I re-installed it, and now the door was as quiet as a modern slider.

More Cards

I had some daylight remaining, so I grabbed the door card for the slider, and installed it. I also installed the card for the wall opposite the slider, and installed it. I did the rear tail gate and the extra cards for the rear-facing partitions behind the front seats. Each of these took some fiddling to get right, but that was on account of Hapy, not because of the cards. These things are great; the holes are mostly in the exactly right spots and the bag of Mollys had more than enough fasteners for me to damage a bunch of them and still not run out. I believe I can fit more sound deadener between the partition cards and the partition, and I may need some foam to reduce vibration noise, but right now, the interior of the bus looks really good. Removing those cards to add noise deadener will be simple when /if  I choose to do it.

I have a couple of cards remaining to be installed along the seat pedestals and I'll do them as the mood strikes / time permits. For those keeping track at home, I have installed the panels which sit at either end of the rock-n-roll bed, arching over the rear wheel wells, and have I attached the panels that cover the bare steel in the sleeping area. Because the sleeping area cards abut the rear-wheel cards, I needed to do them in the right order. As you can see in the image on the right, here, these cards, when used together, make a nearly seamless span. Boo and I will especially appreciate the sleeping area cards when we're camping. There are few things as jar-awake as having some bare skin touch up against the metal side after it has cooled down overnight. That is some quick-awakening. While this plastic / PVC will not be a great deal better, it does create a foundation for some foam and then some fabric later.

At this point, I felt ready for a test flight. I'll post on that next time. Thanks, as always, for following along-

Zed Prime

No, not like Optimus Prime. Today we celebrate getting Zed primed in 2k hi-build primer. Before I begin, the CoViD numbers are getting flat-out scary, but it doesn't seem like folks are taking this news and processing it into action. I take a walk every afternoon for some exercise around suburban residential streets and there are lots of fellow walkers or runners out there. Please remember that just because you're outside, it doesn't mean you can walk right up to me without a mask. I'm wearing one to protect you; show me the same courtesy, dammit. Now, about that primer.

Layout

set up for ease of movement

I started out by backing Nemo out of the other covered spot, and laying a big blue tarp on the driveway where it had been. I then planned my route for moving from panel to panel with a spraygun and air hose. I moved the air compressor out of the garage, but at the edge of it's power cord. I wanted to make sure I could get at different angles without bumping into wet paint, and without dropping the air hose across a panel.

Clean

This is the part that most car shows don't televise: the endless cleaning. Garage Squad is the clear exception, but I think that's because the car owner is usually doing it. Anyway, by now, dust from the Bondo is pretty much everywhere. Your hands and the oils ever-present on them (combined with Bondo dust or not), have run all over all of the panels. Both of these things ruin paint jobs. So, we start with a bottle of degreaser and a roll of paper towels. Since the car has been outside and the weather has been windy and damp, I did not feel it was necessary to shop-vac the interior before I began. I stand by that decision, but I encourage you to vacuum or air-compressor blow-out crevices at least. With bottle and towels in hand, you clean everywhere you intend to put primer. And clean the places nearby so tape will stick. I found the degreaser left a film on plastic so I had to reclean those plastic pieces with window cleaner sprayed onto paper towel so I could get tape to stick. Neat.

Mask

driver side rear quarter

With everything clean, I completed the masking next. I had started a few weeks ago, masking off the engine bay and the windshield. The sides of the dashboard near the doors, the door seals and some of the door hardware all needed to be masked. The fuel inlet did too. Again, it is probably worth stating that the purpose of masking it to keep paint off of stuff you don't want painted. That sounds obvious, but sometimes we get aggressive with tape and overdo it. So, with that perspective, it is better to under mask and have a little bit of rubber or chrome get paint on it than to over-mask, and have a line of unpainted body when you pull tape. Been there; it really sucks. Removing a little paint from rubber or chrome is way better than trying to get paint on that edge after you've messed up the masking. Last, I cut up some kitchen garbage bags and covered the tires. I'm not sure if we are going to keep them or not, but either way overspray would make them worth less. 

Paint Gun Assembly

I knew that once I had metal etching material applied, I was all-in on priming. Metal etch is an acid that converts rust, but it also cuts into the steel, making primer adhere better, but also creating a means of rust suddenly appear where it otherwise wasn't. With mid-Fall NorthWestern Oregon weather (read: damp), you do not want to create a rust opportunity. So, I set up my paint gun next.

A while back I got 3 of those purple Harbor Freight paint guns. I figured I would have a different gun for each of the various steps: prime, paint and clear. Well, since then I got a much better gun (ATOM X27) for applying the color and clear. For primer, though, especially this high-build stuff that has some thickness to it, I did not want to put that through the new gun.

The purple Harbor Freight paint gun ships with one tip, a 1.4mm one. That is too small to reasonably throw thick primer. The Eastwood guide for this 2k high-build primer suggests anything from 1.8 to 2.5mm. So, I drilled out the 1.4mm tip with a 5/64" (1.98mm) drill bit to get as close to a 2mm hole as I could. I did this a few weeks ago during paint gun disassembly, cleaning with lacquer thinner and re-assembly. Now, with the gun set up with a nearly 2mm tip, I was about ready. For timing... from end-to-end, gun disassembly, tip-drill, cleaning and re-assembly took a little over an hour. I work slow.

To the air-inlet, I applied plumbers tape, and then threaded on a regulator with a pressure gauge (like this, also pictured on the right here). On the threaded end went more plumbers tape and then a inline desiccant dryer/filter (like this) and more plumbers tape. To that last bit, I threaded on an air hose quick-release. I set the whole contraption into a spray gun stand (like this) that was held firm to my bench under the weight of a vice. Be advised, these things are not balanced, and need to be fixed to something -or- have the baseplate under something super heavy (like a bench vice that I never attached to the bench) or they will fall.

Etch

With the panels clean, the gun ready and the masking done, I grabbed my small bottle of Eastwood metal etch and a foam brush. Panel by panel, I liberally applied metal etch. Because it was in the upper 50'sF (14*C) and relatively damp, the metal etch stayed wet for quite a while. That's a good thing, as it gives the acid time to cut into the metal and convert any rust without creating flash-rust.

Mix a Batch

hood looks real flat

Again, not like Letterkenny. The Eastwood hi-build 2k polyester primer requires the addition of liquid hardener: 0.2oz hardener per 10oz of primer. The cup that comes with the purple gun max's out at 20oz. so, I made 15oz batches per spray cycle. 15oz of material needs 0.3oz of hardener. Now, I have an old plastic syringe from when I was playing with biodiesel years ago that holds up to 12ml's, but it is graded in milliliters not oz. Apply some math and we need 8.87ml of hardener for 15oz of primer.

I grabbed a plastic mixing pitcher from the kitchen baking materials (did I mention that my wife loves me? I'm a lucky man.) and with blue tape marked the 15oz. line with the top edge of the tape. I did this so that I could quickly see when I hit 15oz while dumping paint from a 1-gallon pail. I opened the can, and then spent about 15 minutes thoroughly mixing the primer, deep churning the solids off the bottom so it was consistent top to bottom. 

Once mixed, I poured 15oz into the mixing pitcher (to the top of the blue tape) and opened the hardener. The hardener comes in a tube, but is as thin as water, so getting it into a syringe was not really a fruitful exercise. To solve, I removed the plunger, turned it upright (small hole at the bottom) and covered the small hole with my gloved finger. Into the now-open other end of the syringe, I squeezed just shy of 9ml in and then dumped it into the mixing pitcher. I mixed for about a minute and then poured the now-activated primer into the gun paint cup and threaded on the lid. I repeated this process 3 more times during the primer-shoot.

Prime

With primer in the cup, the lid fastened, the air compressor turned on and my painting overalls on, I was ready to go. I set the air pressure at the compressor to 40 and played with the regulator at the gun to get to 30psi while spraying. I got there, but I think, in retrospect, it would have been better had I run the pressure at the compressor higher so I could get more pressure through the gun. I say that because I found that the fan was not as wide as I would have liked, which forced me to hold the gun closer to the panel (like 4 inches rather than 6-8).

It is recommended that you test your fan on cardboard. I was shooting primer and was going to be shooting multiple coats, so I was fine with getting the fan set on a fender while shooting. My car, my choice. It took me a few passes to get my pass-speed right, but after 3 coats, the coverage looks really good. I found that I was initially moving too quickly, making my first coat quite light. Also, because I have a 21 gallon air compressor, I had to wait for the pressure a few times. Honestly, I expected much more waiting.

Because of the high-build nature of the primer, I made sure that I got a nice build everywhere, and then circled back on the trouble spots (fenders) for some extra. Once it all dried overnight, the panels look very smooth, though after touching them, they will definitely require a bunch of sanding. I haven't decided if another round of primer will be necessary. I guess we'll see after the sanding. At this point, though, I am super-happy with how everything looks.

Clean Up

passenger door

Similar to the cleaning of the car prior to painting, the cleanup of tools gets virtually no coverage in MotorTrend / Velocity / Speed television shows. That's really too bad. I know it isn't terribly entertaining television, but ignoring it implies a bad habit of not cleaning things as the way that the professionals do it. We know that is absolutely not the case. I spent over 2 hours spraying primer and another hour cleaning up. I may be slow, but I try to be meticulous. I started by pouring some fresh lacquer thinner into the paint cup and sloshing it around. This didn't free the dried-on primer, but the still wet primer was now suspended in lacquer thinner. I sprayed the material out until the cup was empty, and then removed the air line from the gun. I removed the cup and set it aside while I poured more lacquer thinner into the measuring pitcher. I used the pitcher from this point as the cleaning "sink". I dunked the cup in the "sink" a few times while I cleaned other things so the remaining paint on it wouldn't dry.

I removed the mix nuzzle (on the end that sets the fan-direction vertical or horizontal) off the front spray gun and then pulled the needle from the rear. With a pair of channel-lock pliers, I removed the tip housing, and placed them all into the pitcher. I set the gun in last, upside down. I added more lacquer thinner and then started cleaning things with a brush, getting all primer off of everything, including the outside of the paint gun housing and the paint cup. Once everything was completely clean and wiped down (an hour later), I re-assembled the gun, wiped out the paint cup and put everything away.

Some might argue that these guns are only $15US so why bother cleaning them. To me, treating them as single-use is an environmentally hostile way to operate. Ideally, I would not even have these, and I would have high quality tools (like the ATOM X27) instead. Still, the way we treat our expensive tools is how we should treat our cheap ones, IMHO. I have heard that these start leaking after no more than 10 hours of use, so I may have a couple more jobs before this starts to fail on me. That's still more than once. 

Curing

I let the panels (and the main shell, of course) sit in-place and under the carports overnight. The following morning, it had started to sprinkle so I carefully moved the panels back into the warm garage. I will let them sit until I am ready to sand the primer. I expect I will know if another round of primer will be necessary or not from that. Either way, the window for painting this Fall is effectively closed. Even if I can get sides onto these carports, it will be very hard to warm 400 square feet of space to 70*F (21*C) when it is under 40*F (4*C) outside. Any cooler than 60*F (~15*C), the paint won't behave properly, and it seems like everyone encourages painting at temps closer to 70*F (21*C).

I have read that the polyester primer can protect the metal underneath if the primer is not disturbed (read: sanded). Once you sand it, it is much easier for moisture to get in. I don't know if that's true, but I will be leaving the car un-sanded in primer since I can't get paint on it, so we'll find out. For now, everything except the main shell is in the garage. The shell is sitting under a car port. So, it is semi-outside, but out of direct weather and (extremely limited seasonal) sunshine.

Thanks, as always, for following along. Once the Zed body parts were moved out of the car port, I moved Hapy in, so I expect to be returning to Hapy work in the next few posts. 

Peanut Butter (no Jelly) Time

No, I won't post that dancing banana video from a few years back, but I will reflect on a valuable use for peanut butter that I didn't expect.

That's Nasty

old pic from 2011 but
check the nasty back-end

When driving along, the air directly behind the vehicle creates a vacuum.  Car designers have worked all kinds of miracles in that area over the years, but with the old loaf-of-bread shaped VW bus, the vacuum is quite significant.  I've heard of water-cooled transplant failures caused because the builder put a radiator where the engine hatch is.  The vacuum made the radiator useless, unless the builder had the fans suck air in from behind, sort of leveraging the vacuum.  Even then, those installs look pretty atrocious and would pull all kinds of crap into the radiator fins, but I digress.  The vacuum grabs up water, road grime, dripping oil... and splats it on the rear bumper, engine hatch and rear hatch.  Over time, it gets pretty grimy.

In my bus' case, it was worse.  I mentioned the transaxle gear oil leak in previous posts.  That was bad.  On top of that, for a few years I was running the original tail lights and the old housings failed.  I was broke, so I held the tail lights on with duct tape.  Yes, the bus looked horribly ghetto.  I scored a pair of new (but not China-crap) housings from the BusDepot when they were on sale a few years ago, and replaced them.  I did not, however, clean up the old duct tape sticky residue left behind by the tape.

For the Greatest Shine You Ever Tasted (from the SNL Shimmer skit)
While cleaning out the garage, Boo came out from playing in the garden and started asking about the nasty back end of the bus.  We realized that once the newly painted bumper is put on, it will look even worse.  She ducked inside, and I went back to the garage.  A couple minutes later, she had returned with a fist of paper towels and a teaspoon of peanut butter.  "Hungry?" I asked.  "No, haven't you ever done this before?" she replied, and then proceeded to put a dab of peanut butter on the nasty duct tape.  "uh... what... are.. you..," was as far as I got as a response before I saw one of the 4 tacky squares which had been left behind by the duct tape had disappeared.  In a few minutes, all 4 of the big black marks were gone.  I was converted.  I left the garage in its not-yet-organized state and grabbed some peanut butter.  I polished the whole rear end with that magical stuff.  It acted like a cleanser-wax, cleaning the oil and grime while leaving a shine (presumably from the oils in the peanut butter).  Of course, there are probably lots of little peanut bits in there which would trash an otherwise nice paint job.  For original paint, complete with rust, patina and grease-finger prints, it is magic.

For kicks, I peanut oiled all of the little rust spots I had.  The petina-style rust didn't seem very affected.  Rather than a dull spot, it shined like the paint, but otherwise, it was about the same.  The rust which was a little deeper into the steel, though, did react differently.  The rust closest to the paint was unaffected, but as I moved more than a couple MM away from the paint edge, the rust turned silver.  Trippy.  I'll re-check those spots in a couple of days to see if that lasted or was just because the peanut butter picked up some of the body color and it simply attached to the rust a little bit.  Regardless, the experimenting was fun.

Like so may other times, I didn't take many pictures beforehand, but I do have one here of the back after it was cleaned.  Wow.  And there's a shine to it now.  Yes, the paint is still atrocious, but that's part of the ongoing work-in-progress.  The journey is the destination.

Of course, it rained all night the next night.  It will be interesting to see how long a peanut oil wax job will last in a NorthWest autumn (read: nearly constant rain or mist in the air).  Today, it really looks great.
