I have read several posts in other wesite forums about the 3M and other clearbra subjects. It seems to be a general consensus that it should be done by a "professional" installer as it is very difficult to "install" properly. Several posts from people with Lexus vehicles swear by it (not the one on eBay), but the 3M type. If you "google" 3M front end bras or something along those lines, it will give you several websites with a lot of useful info. Some of the potential sites: Car Bra Clearshield Car Bra X-Pel Clear Bra-3M Scotchgard Protection Clear Mask Rock Blocker.com Just to name a few. Hope this helps; NORT
