If you have it repaired and refinished you will not any other problems. The bubbles are from the adhesive gm used and when it cures it puts off the vapor that causes that. I've fixed 5 cars at work and they have not messed up yet it's been 5yrs for my personal car and I just fixed my hoss about 6 months ago
