Squished Paint? Bolting things back together

I am not sure that I can do anything about this problem but here is the history. First off I took everything down to Metal and used PPG DP50. Let that dry for 2 weeks. Sanded that with 400, then applied PPG DBC, then applied PPG stratoclear 2082. The job turned out looking great. I waited about 2 days to sand the clear then another 5 to machine polish. Real happy with the result. Started bolting parts back on motorcyle 10 days after application of the clear. Well where the bolts come in direct contact with the paint it squished the paint creating like an upside down mushroom. And where the seat frame came in contact and bolted down the paint looks flattened. The painted parts had been in my house at about 65 Degrees for that 10 days. Whats up with that? Shouldn't it be cured by now? Do I need to worry about it. Is it a adhesion problem. The only real difference from this job and the norm was that the shop temp was pretty low, 55 or so. But I did use the DT 860 in the DBC and the fast catalyst in the clear. Is the epoxy not yet cured?

By the sounds of it the paint or clear was put on too thick. I could have been prevented by baking your work after you completed it. If you want to fix it your going to have to sand it down and touch up the clear.

Alot of times to, if you put the base on thick, then put the clear on too quick, it "seals" in the basecoat, thus not letting the paint cure properly. Doing this will give you a soft basecoat, and the clear will be hard. Kind of a "sandwiched" effect.

This will do what you are talking about. It will also chip fairly easy.

This is common among candy jobs...putting a clear on that will dry quicker then the candy below it.

PS--I moved your post for you---thanks.

Scott,

I thought that I waited long enough for the DBC to dry. But it was probably too cold for it to fully cure. I waited about 18-20 hours from the time I stopped applying basecoat till I started my first coat of clear. The Tech sheet said I had to clear within 24 hours. I knew that I probably had a little more time than that because of the shop temp being in the 50's. But I think that this is a prime example of why you need 70 degrees minumum. And no matter how advanced the chemicals get it is a good idea not to fall too outside of standard conditions.

Thanks,
Doug
