I agree. I have the film on my Tahoe and I have still gotten a couple chips on my bumper. I paid $900 for my film. I dont think anything can really stop the chips but one of the bra's for the whole front facia. But we all know what those look like. lol. But they DO work. IMO, I really dont think its worth the money really. A friend told me he throws a nice good wax on the front facia and it helps him. I tried it once and it was ok. I still got some lil chips tho.I had 3M paint protection film installed on my MS6 shortly after I bought it. The shop charged me about $700 for the front bumper, front edge of the hood and fenders, side mirrors, and rocker panels.
The protection film definately helps reduce chips and scratches. but the paint on these cars is so brittle that nothing can completely prevent damage. I have a couple of spots where stones have cracked the paint under the film, and one spot where something chipped right throught the film and paint! :swearin:
If you do a lot of highway driving, especially in regions with lots of dirt and gravel on the roads, the film will probably help extend the life of the paint on the most vunerable areas.
However, I've realized that if I ever want the car to look really nice again, I'll need a new paint job. If I ever decide to go this route, I hope I can find an aftermarket paint that is much, much, much more durable than the brittle stock finish.
