I have never had a bad experience with bra's. I had one on my '95 Avenger (Dark Green, LeBra brand) for over a year and on my '01 Stratus R/T (Silver, factory embroidered) for over a year. I saw no paint fading, dulling, or scratches. I did not leave it on for extended periods of time in the winter and would wash my vehilce and bra at least once a week if possible. I may just have been lucky with my cars but I know that it sure took well to the always changing seasons of Cleveland. Everyone has thier own view and opionion, mine just happens to be a positive one. I guess you learn by trial and error.
