Default 89 vette bubbles in paint advice

Salute my friends, I am near Vancouver, Canada looking for a body shop to repair both rear body panels (not the bumper). Here is a short version of a long story: In 2006 someone hit the rear of the car cracking the body (up top) to the right of the gas tank lid. A typical body shop did the repair. Over the years that repair broke apart and the paint seperated from the body. I still have the receipt and went to that same bodyshop yesterday. They said they would warranty and repair it which is good, but here's problem. Since 2006 tiny bubbles under the paint have formed in both rear body panels. So I suggested to the bodyshop that I would pay them to sand down the paint to get rid of the the bubbles and then paint. They said they would, but could not garantee the bubbles won't come back. Anyway, I was hoping to save money because of the warranty repair, but I am not sure they are using the right products and the bubbles will return. So do I take a chance, or look for another bodyshop is the question. Thank you for your advice and insight......or a body shop near Vancouver.

bubbles in the paint can be caused by several factors. the first thing you need to do is educate yourself so when you're talking with the body shop, they don't have you at a disadvantage. google can be your friend here - try "automotive paint problems bubbles." if bubbles appeared sometime after the repair, I wouldn't think is moisture related, or solvent pop in general, but gassing due to a chemical reaction or contamination of products. I've done some painting, but anything I can tell you is second guessing. as far as what to do, personally, if the original body shop will back their work, make them fix it, and take you chances. you might try posting this over on body and paint forum, and address forum member DUB. he has a massive amount of knowledge, and experience with corvette paint and body work in general. good luck -

I agree with JoeC on making sure you can deal with them from an educated perspective. Also many shops still think Corvettes are fiberglass and not SMC so they continue to use repair products that are intended for fiberglass and not SMC panels. This too can lead to paint issues, cracking from different rates of thermal expansion, etc. Non Corvette shops continue to use wet sanding for prep work and this is not recommended due to water retention leading to paint bubbles often a long time after the repair. Drying panels not sealed where water has had a change to penetrate can take a long time to effectively eliminate all moisture.
The paint and body section will be your friend.
