We just bought a new car (well, small SUV, Ford Escape), and of course I want to keep it looking great. I was looking around online and saw these clean paint protection films that go on the front of the hood, front, and other areas that get pelted by rocks to protect from chips. There are a few different brands, one made by 3M. This place sells the products you can install yourself, although I'd likely get it professionally installed. Has anyone used a product like this? Can you really notice it when it's on? Does it work well?
