i have a 66 roadster, 16 months ago i had it painted back to the correct color, laguna blue, it was red before i painted it and upon sanding we could tell it had been maroon and possibly black in the past, we did agressive sanding before painting and no defects could be detected, for 6 months there were no visible defects, now on the nose and both front fenders more defects can be seen every time i look, some look like little bubbles in a line that looks like it might be a rivet line, and some are wavey and almost look like drip marks, the defects are not in the clear coat and are limited to the nose and front fenders where i think prior repairs must have been, i don't remember the paint shop putting any sealer on in the process and we didn't take all the red paint off because it was very tight and in good shape, what is causing these defects to show up now? what can i do to prevent them? is this a process called outgassing? we painted the car one day after wet sanding, did we not wait long enough? thanks joe

Re: C2 paint problem
Even at the factory, body panel seam lines were notorious for generating 'blow hole' defects that factory and dealership painters fought all the time. Since you paid someone to paint the car for you, it's a 'warranty' issue that he should be willing to honor and fix. Most strip down to the bare glass, use sealer then primer allowing each coat to stabilize and hand sand/spot defect areas before proceeding to the next surface coat to thwart such slowly developing 'time bomb' defects. -
Re: C2 paint problem
Sounds like way to much material to start with. Agressive sanding????? 4 to600 grit is as agressive as should be used without p******* and resanding. If it was not stripped and no body work was done you could have modern paints and hardners reacting with old paints. Any car with that many paint jobs should have been stripped.Again WAY to much material... BillComment
