When I did the Bullrun, team Lamorghini, team Lotus, and our Hurst/Olds all had the 3M version, my brother has it on his new Jeep SRT-8. It did protect the cars a great deal. When the Lamborghini team struck a huge racoon, the film held his carbon fiber bumper together and kept it from completey tearing off. But proper installation is key, its best left to a professional. The car needs to be well cleaned, smooth no chips otherwise the chips may rust and the grime will make the film very visible and probably not adhere well; so all that has to be addressed before applying the film. When dirty/dusty the lines where the film ends are very visible. Last week I thought someone had keyed my brother's Jeep, but then I realized it was just dust accumulated by the edge of the film. The film does hold on well though. Not cheap.
