What all is coming off? Is it all of it including primer and you have exposed fiberglass?

If you used chemical stripper and did not 'bake' the volatiles out of the glass...or, if you did soda blasting and did not neutralize the acid, you might end up with that result.

Did you strip it completely? I have seen blistering like this when (for instance) lacquers were applied over synthetic enamels. I know almost no one uses these anymore, but there's massive incompatibility of some sort here. Was the car allowed to air dry at least 36 hours after last water rinse/before first coat primer? Did you final wash bare glass with lacquer thinner then apply first sealer immediately?

Didn't you mean alkaline


Whatever it is, looks pretty thick to me, maybe a filler coming with the paint.

WOW....sorry to see that. I have done a few vetts, and I know how much time goes in to getting a car readyIf you used a 2 part epoxy primer and painted right over it before it cured completely( a couple days ) it "could" produce bubbling or a dull looking finish, but that is really nasty. With bubbles that big, it looks like something was still evaporating at a pretty good rate. How long after painting did this take to show up?

In that first picture, it would appear that the peeling has originated right at the fiberglass. That would tell me that the glass had some contamination on it that didnt allow the primer to stick to it.
