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

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.

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

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-
