I recently painted my skylark. We did a good prep and used wax and grease remover and wiped and tacked it off. problem is i am getting paint blisters two unnoticeable and one the size of a quarter was wondering if there is anything i can do. i am pretty sure it will mean a trip to the both again just though i would ask all you great buick guys

I once saw a guy shoot enamel paint over lacquer and get the effect you're talking about. Something about the differences in
chemistry not allowing one to bond correctly, actually causing it to "lift".
Don't know if this is your case, but if so....better invest in some stripper.

It is pretty hard to tell you what it is without seeing it, but I would guess it was there all ready. You painted over it and now it has reared it's ugly head. It sounds like an air pocket that the solvent from your new paint has lifted. I know this sounds nuts but there is really no way this can happen with the new paint alown. Shadrach may also be on to something, either way it is something that was there already.

So it seems that because i wet sanded the old lacquer paint and applied the new paint there could be some adheshion troubles with the new paint to the old lacquer paint. In preping the car this should mean that i should take it all the way down to metal apply a self eching primer and sandable urethane this should correct the problem other than the normal wax and grease remover and a tack cloth do you have any other reccommendations to applying the paint again?
thanks for the help!

Applying the color over the lacquer is not the problem, there was a problem with the lacquer and maybe only in that one spot where the blister is. To strip it, etch prime, urethane primer, and paint would be the best thing to do, but I doubt it is neccessary.

So what i gather from the info that was given to me is that it is ok to paint over lacquer it was just a bad reaction to the old paint or maybe just a bad prep in those areas thanks for all the advice

I think it is more likely a bad prep problem with the lacquer job. The lacquer (not that lacquer has anything to do with it) had a flaw with adheasion that the new paint took advantage of.

There is one thing that I have to say. I have not seen the car and what you see may not be what I am seeing. I may be off a mile, It just sounds like problem with the previous paint. There is no reason that I have ever seen that would cause a paint to lift in such large areas. It would wrinkle or something like that, which again we would be going back to what was underneath it.

Thanks for all the help with the paint i will probally try it again the lifting seems to be going down as well. but that a hole new story.

thanks

That goes with what I have been saying, the air or solvent pocket is "going down" because what ever it is, is being disapated through the paint. OR if it's air, it has been heated and it expanded. This could have happened because it could breath before and now it is sealed under the new paint.

the only thing i can add is to try a "sealer" type primer. it seals old paint from new ( just in case the paints are not compatable).
