one type material is call invisable bra i think, basicly clear film about 5 mils thick

THe 109872349879203475190845 use for Duct Tape!!!

Try Stongard Have used on a couple of my Audi's. Not optically correct but I wonder what is?

Some BMW/Mini dealers offer some type of clear film that will cover headlights and painted areas that are prone to stone chips. I've seen quite a few Mini Coopers around with this applied. You could try calling a local dealer and ask what they use...
