Thought I would share my experience and save some of you the same grief.
I acquired my BDR used and it already had the 3M bra on it. Lately it has started to yellow so I took to the guy in town that everyone says to use. His advice, jokingly at first, was to sell the car. The older 3M's had a SUPER strong adhesive that is hard to get off.
He was able to get mine removed but not without pulling some paint off. Luckily, I a) have touch-up and b) it is located in areas near the bottom front of the car (not that noticeable).
He told me had I waited-- it could have been worse. He said a year or two earlier might have prevented the whole situation.
Good times!
