Hi all, after about two and a half years, the 3M clear bra on my car has become noticeably discolored on the rear quarter panels and I want to remove it, have the car detailed and then have the local exotic shop put a new one on. I'm concerned with removing it properly to not cause any damage; has anyone done that, any tips, etc.? I was just going to remove the rear pieces, the other parts of the car still look fine.
