Paint Blister
My Corvette is coded Nevada Silver but was repainted Milli Miglia Red by the previous owner. To be more accurate, it is a single stage re-spray with a fairly presentable finish. I have had a couple minor issues with adherence of the paint, but now have an unsightly blister in (under) the paint, the size of a quarter on the rear fender. Is there anything I can do to stop the spread of the blister and diminish its appearance? I was hoping to drive the Vette a few years while I got the mechanicals sorted out to my liking before tackling the cost and labor of a quality paint job. I’m still working on the mechanicals. Any suggestions for a temporary fix to my paint issue are greatly appreciated.
Thanks
Pat

All the silver should have been removed. Silver sucks for adhesion. The average silver paint job doesn't usually last more than 5-10 years. Obviously, it depends on the care of the car, but that's a good rule of thumb. Try the pin trick, but the bottom line is, the paint lost adhesion right there. Short of sanding it down and re-shooting it, there's not much you can do. I have a wart that popped up on the hood of my Nova for seemingly no reason. I went back through the pictures and can see nothing that would've caused it. I'll have to grind it down to bare metal, re-fill that section, then repaint the hood to make it go away.

This is typically caused by improper preperation, or someone used a chemical stripper, or got chemical on the body. Even chemical on the BACKSIDE of the fiberglass can bleed through and do this.
The bad news is that it only gets worse with time.

I will try to puncture it with a pin. Hopefully that will stop/slow the spread. Judging from the amount of overspray, I would say it's a preparation issue. The blister is in a pretty comspicuous spot...doubt I can get it to match with my limited paint and body work skills. There is an inconspicuous area with some blistering and chipping that I might try first to see how it turns out.

I would bet the prep was not done correctly when it was painted. I have an 81 that was painted at the St. Louis plant with enamel. It now has base-clear lacquer, I helped along with all the prep work. All the old enamel paint had to be removed down to the factory primer, and what a messy job it was.
My painter told me it wouldn't be a problem to spray acrylic enamel paint over acrylic lacquer, but applying acrylic lacquer auto paint over the acrylic enamel paint he said would result in wrinkling or other surface blemishes due to the solvent base in acrylic lacquer auto paint (lacquer thinner) being too potent for the soft materials used in acrylic enamel paint products.

I noticed you didn't quote the next sentence of my post where I said it depends on the care of the vehicle. If you parked a silver car next to a black car outside in the weather, the silver WILL fall off before the black will.
