quite interesting IMO, probably not as protective as a traditional bra, or plastic deflector, but its versatile and removable. Ive used racers tape inthe past on the fronts of my cars on long trips, but they will still leave residue and it looks quite crappy. Id never put a bra on a car, but this is a possibility.

$8 a can is much bettter than $20 at Griots Rip Off Garage. Comes in a gray or clear.
