I had an acura integera with a 3 year old 3M clear bra installed. It started looking bad from the rocks hitting it.
The way I went about removing it was by heating it with a blow dryer. The job goes much quicker with a buddy.
We heated it at one end being careful not to stay on one spot for two long and very slowly peeled back. Some spots
were very stuck to the point the blow dryer was not having any effect and th film was pulling on the bumper. In
those instances we applied 3M adhesive remover. It took quite a long time but no damage was done to the paint,
however a lot of adhesive was left on the bumper. More 3M adhesive remover was applied then the area was machine
polished. That bra really saved the bumper from rock damage. I have heard of plastic razor blades I have not used them
but something similar would be very useful to get that first corner off, we used an old credit card.
