Wrinkel Paint

T

Toms 57 Chevy

Well its been a while since I posted anything. The las post was the trouble with my roof. Any way stripped it down and repainted it. Turn out good. Now I have started painting the body siulever. I am using Prospray. I sprayed the silver but it did not look right. It look good from straight on but from angle is was blotchy. Of course I did not see this untill I had 3 coats of clear. I called Barry on the tech line and he told me to wet sand the clear and reshoot it. Well yesterday I wet sand the car with 600. So today I shot my 1st coat and it looked good, I got it lay flat and it was a big inprovement over the first time I painted it. Waite an hour to shoo the 2nd coat. Got done and then I saw the wrinkel .I dont know why or how come. Callled Barry he told me to let it dry and then wet sand it with 1500. I waited 2 hours and it just peeled to the primer. So I sanded 320, 400, 600 and have shot 2 coats of epoxy. I am going to try to blend it in tomorrow. Also has a litte spot on a passager door and rocker. Hope I don find any more. My question is am I doing this right? photo (1).jpg

Dont know why it lifted:livid:
 
If your base was blotchy you were laying it on too heavy and/or not waiting long enough on your flash times.
As for the wrinkled paint, my guess is you sanded through the clear with the 600 and when you shot your new clear the solvents ate into the exposed base coat.

I looked at the epoxy I laid down and it looks real smooth. So hopefully the paint will blend.
 
was your basecoat activated? when you start layering up base/clear/base it becomes a touchy situation when everything is fresh
 
Bob, the paint was activated. It was funny because the 1st coat laid down nice and the 2nd not so much. I had a few other spots low on the car at the passener rocker and a small one on the door. I have fix all of these. The big one sanded 320,400, 600 and shot 3 coats of epoxy. Then bended the paint. I still have to fix a place or two this has a little stripping on the side . I am going to lower my side lights so I can see what I am doing. Got any clues on how to make sure I get it looking uniformed?
 
I use a very bright light. Like the 3m sun gun. But I built it myself. About 1/4 the cost. But it's used mostly for lower corners, edges ect to make sure I have coverage but I think a good light would help a lot.

uniformity comes from the proper gun set, distance from panel, speed and so on.

With some colors a drop coat can help.
 
Wrinkles happen when your under layers aren't wet enough to achieve chemical bond but not dry enough to resist heavy coats of solvents, they soak into your lower layers and cause them to lift and wrinkle.

As for spraying high metallic base, spray your first 2 coats as you are the come back over and spray cross coats about 10-14 inches from panel and on the very last coat you can even cut your base 1:1 with clear base coat to help blend out the stripes/modeling. That blotchy look ( modeling) is from heavy coats. Think of it like this. Drop a dime into a mixing cup with a 1/4 inch of water in the bottom, its going hit the surface and fall flat, now fill the cup full and drop it in. It will tumble and roll around before it falls flat. Times that by 10000. If you spray really wet coats the metallics will land in non uniform angles but if you spray thin coats from further away(less solvent transfer) the metallic will lay flatter.

Are you saying that because the basecoat ended up getting sanded? I mean the clear always goes over exposed basecoat.

I have been looking at this for days, are you sure you didnt rub up against it or lean against the car? It almost looks like a palm, rag or even a coverall type splotch. I know nobody mentioned it and dont want to be the asshole, but also thought you might feel better if it was something that had nothing to do with how you sprayed the car.
 
No I did not touch the paint. I am going to lower my side lights and try to do a drop coat to even things out. It looks pretty good, but have a few areas to work on.
