Hmmm the 3M stuff does apparently breath. The place I got it done (all front bumper, half of the hood, fenders, mirrors, rear sill) said that if there are any bubbles, they will dissapte in a day or two. I had about two very small bubbles that I didn't touch and they did go away.
I'm very glad I got it done. Yes, it was a bit of an expense but if I could get a super price and even do the doors, I would of. GOOD film, you really don't see the line and is completely transparent. I saw another SGM with tint and a clear bra, most likely NOT 3M (different cut pattern than the standard cutout) and it was more yellow and made the car look gross.
