hello guys, i tried doing a search but couldnt really find what i was looking for. i just came back from the track and had quite a few tire rubber marks on my clear bra as well as on the car. now the marks on the actual paint came off very easy, but i cant get them out of the clear bra for nothing. i need some help on getting these removed. when i tried scrubbing with the sponge it leaves scratches on the clear bra and claying didnt help either. please help!
