Bubbled paint on seam sealer
My car was recently painted with a candy, and it has bubbled up/peeled away from any location that has seam sealer (epoxy?) on it. This may be obvious to everyone, but I'm a newbie, so I want to make sure we're on the same page... the stuff I'm talking about is used anywhere a panel skin is wrapped around a framework, like outer door skins, trunk lid skins, etc. You can dent the stuff with your fingernail if you press hard enough.
Obviously paint normally has no issues sticking to this stuff as factory paintjobs cover the sealer without issue. So my question is, why did this happen and what can I do to avoid it during the repaint? Would they have put new sealer on (no damage to car whatsoever) and caused a chemical reaction by failing to let it dry? Bad luck? Poor paint prep? One shop I spoke to said they always strip the sealer out before painting, leaving me with the question of why so much sealer is needed in the first place.
The shop should have fixed this before letting the car out of their sight, but they were already on the edge of a lawsuit from me, and I just wanted the car back in my posession. Now it will be up to another shop to fix their mistakes.
we always use a 2-part seamsealer from 3m ,some people use an older product called dripcheck, or some other noncatylized product. it works for us it is called heavybodied or their self leveling which is excellent in driprails. when it is dry it doesn't shrink at a later date causing cracks.
I was really confused by this one... there was no damage to the door, and the stock seam was in perfect condition. Other than sanding/priming, I saw no reason to remove or replace the current seam sealer. They may have done so, but I can't imagine why.
Any reason for the paint to bubble there you can think of?
