On my rear fenders i have alot of rubber from when I went to the track stuck to my paint and no matter what I put on it, the damn rubber stains wont come off what should I do to take those black rubber stains off?

 

might be a long shot but maybe try a clay bar. i know when i clayed my truck it took alot of stuff off i didnt think would. if the rubber is off try compound then polish.

 

Yea the rubber is off it just left a black residue that is being stubborn and wont come off.

 

castrol super clean.

 

I used some gasoline and a microfiber towel to do it and it worked. Then I went over it with some quick detail to finish it off. Thanks for the input tho guys!
