I've put xpel headlight guards and fog light guards on my wife's '02 Envoy. The stuff is great. It stays cloudy, blotchy and rather ugly for about 2-3 weeks, but after that the moisture evaporates/dissapates and it's smooth sailing. The stuff really is rock proof, and it's a good way to save you from getting cracked lens assemblies (nowadays these things run into the $100's of dollars on pretty much any car...).
I decided not to put it on the hood and bumper given the looks of it. It is clear, but there's a definite edge to the stuff that is easily visible, which I would not like on the paint. It's great on headlights and such, but again, I didn't think it would look too hot on paint. I purchased a bra for the car instead(which I only put on when we are making long highway trips in the car).
FWIW.
Regards,
