A little while back my friend that it would be hilarious to put masking tape all over my car and draw on the tape. After peeling it all off the tape left whatever they drew on it on my fenders, not anywhere else. I have used soap&water, and Mothers Back to Black to remove it but neither work, any solutions to this problem. The fenders are just black plastic if that makes any difference.
Any and all help is VERY appreciated!!
