problem painting bumper 94 Vette
Hi All
My 94 has had a repair to the front bumper ( previous owner ) that is now showing up through paintwork. Had the paint redone here in the UK by agood paint shop ( do show cars here ) but after 3 attempts thje original repair area starts to bubble/lift the new paint but only after about 3/4 days??? any ideas as to what i can do ? maybe put on a barrier coat of paint 1st? the paint shop has no experience of the Vette plastic bumpers causing this prob;lem. They repaired and repainted my rear bumper last year fine!
Any suggestions greatly appreciated

This advice is coming from someone who does a little paint/body work on the side but admittedly is quite the novice. Plain and simple the material used to fix the bumper won't chemically bond to the specific paint the body shop is using. I had this problem on a used bumper I purchased one time. I just wet sanded it real good and painted it using the existing paint as a base/sealer. Well when the paint started to dry it would crinkle. I thought I just didn't prep the surface good enough. So I sanded it back down, and went over it several times with prep solvent to make sure the oily residues were gone. Still got crinkles. Come to find out the original paint that was on there was causing the problem. The bumper had been painted in the past and what I assume was a cheap grade paint was used. I was using a good quality base/clear and it would not bond to it to matter what I did to prep. Ended up stripping all the paint from the bumper in order to get it to do right.
As far as you go thats not an option, I'd try to prime it, wetsand, then spray with a sealer. Then shoot the color and see what happens.
good luck
