Had 3M clear on my old black Silverado. Drove 215,000 miles. Took it off. Paint still looks brand new and not a chip in sight. On my 2014 Track, I am going to wrap the hood in 3M CF and clear 3M the bumper, side mirrors and rocker panels. Great investment IMO and even better I can do it myself so if it looks like crap, I only have myself to blame.
