New Back Glass, New Paint, Bubbles...A long story
So, I purchased new tinted glass for my 65 coupe because I added Vintage Air and I liked the way it looked. Not long after the rear window was installed I started seeing bubbles in the paint. I really didn't know what to make of it. To be honest I thought the installer somehow got solvent in the glass. But, because the paint was lacquer, old and tired I decided to get the whole car repainted. The paint looked great. I even won "Best in Class" at the Cleveland Piston Power Show. But, then the bubbles came back. The body shop stripped the paint and dried the glass under heat lamps. Then, the day they were going to paint it the fiber glass was wet again. The body shop owner, who specializes in corvettes, said he had never seen anything like this.
After a lot of "troubleshooting" they finally found the problem. When the guy installed the glass he cleaned all the sealer out of the window channel. A couple of the trim clips were loose ( and now not sealed) so when I washed the car or got caught in the rain the space inside of the double panel filled up with water. It was so full of water that when heated by the sun it would actually pressurize causing it to back up and bubble the paint. They drilled a couple of small holes in the inner panel and had to use a small bucket to catch all the water. Amazing how high maintenance these cars are.
Just wanted to share with you guys.

That's pretty wild. Sounds like your paint shop did right by you. Hope that takes care of the problem.

Now that is a new one on me for sure...
I've fought some paint issues due to contamination....it ain't no fun, it ain't cheap, and, you're never REALLY sure you have it fixed for good.

Some of the push in clips around the car that you push into holes
I have always used some paintable caulk like the new windshield sealers. Anywhere water might enter, seal it up would be obvious. I am glad this topic came up!!!!!!
