Make sure you go to a shop that does this. I made a mistake with a shop that did window tint and told me they "had done these before". It was on a 04 Maxima. Had bubbles that never really went away and the cuts he made were not the best. After 9 months of beating on him he did refund my money.

They do work and sometimes leave a small line when you wax them. However, if you use a detail brush this can be eliminated.

Good luck.
