I had it installed before I took delivery in mid-
June. The application was very good, including fim on the headlight lenses. I believe that they used a 3M mid-line product. I am very happy with the results and am certain that it has and will protect the car from stone chips that can pit the finish in a remarkably short time. I did not apply the film to my black 03 CL55 and within a few months the clearcoat was finely pitted in addition to a noticable chip on the leading edge of the hood from a small stone. I have no doubt that it will not damage the finish. The fine line across the hood where the film ends is noticable only if one is standing next to it when it is parked and even then is not offensive to me. I should mention that am a Zaino fanatic about my detailing, if that helps with perspective.
