Several places claim they install the 3M rock guard, but you have to go to a professional who knows what he's doing! The only thing you have to be careful is when power polishing. Mine recently got some wax under the edges when I got the car waxed, but they are going to re-do the hood. No issues with temperature changes at all.

Take a look at mine. You have to look VERY carefully to even see it. You can only see the edges where it cuts off. I have jet black paint...probably the most noticeable color! I have the film on the hood about 1/4 way up, the entire front bumper and cuts off on the side fenders. Also the side mirrors. Take a real close look...you can't even tell when it's done right!
