I tried to get some feedback on here a while ago about this stuff but i had no responses! So i bit the bullit and went ahead and got it professionally installed. A friend of mine had this on his qx4 for 10 years and it looks good as new still. This is a clear film installed by certified 3m installers, it protects from hood chips and bug/tar stains. Comes with a 5 year warranty as well. The 3m stuff is very expensive, but the other brands are known to fade paint and peel off quickly, ive seen it before on another friends ride. You get what you pay for. I ended up gettingt 12" on the hood and fenders, $280 later it was all done. Lets see how it holds out...at least i have some peace of mind from rock chips i wont do the front bumper yet...$500....yikes...not sure if its worth it. I know repaint never matches perfectly but $500 could repaint the bumper pretty damn close!
