Also did mine within the first few hundred miles. with 13.5K on my car, the bra is JUST starting to show some wear from where bigger stones have wacked it and scratched the bra...however, those stones would have SURELY damaged the paint without the bra there. I figure the bra's are good for 3 years minimum without showing wear if you drive your car a good bit like I do. I will probably have it peeled off and replaced next fall, right before the car goes away. (commonly driving with other vipers in close proximity at very high speeds like I do kills the paint)
But yes, AWESOME investment. However, the next go around, I think I am going to purchase a regular bra to accompany the clear bra for long trips, or trips where rain is expected...The clear bra would be good for 5-10 years if a regular bra was used in those situations. It is amazing how much crap gets thrown at the car when its wet out.
