I like the "invisible bra" concept, but a lot of the stuff sold is vinyl, which is for this purpose, garbage - it's too soft. The GOOD stuff is polycarbonate and supposedly, 3M invented it as a protection on helicopter blades in the Viet Nam war because the blades would get dinged all the time landing on rocks and dirt. 3M sells this to installers, but occasionally it pops up on eBay. I bought some, but by the time I got it, the cows had already left the barn - that is, my front end was ALREADY chipped up. I had intended to put it above the headlights and the lower spoiler on my 380 (that spoiler is similar to a Lorinzer spoiler and the 560 spoiler).
