Today I drove through a construction zone where asphalt work was being done. It was nice that they put up construction or detour signs allowing me to go a different way </sarcasm>. Anyway, I drove through the fresh oil and got the hot asphalt on the left side tires. The left side doesn't look bad, but the right side has the oily tar all over it, and doesn't want to come off. I've tried bug and tar remover to no avail. My Flowmaster exhaust tip is covered in the gunk and none of it will come off. My next step is a clay bar. Anyone else had to remove this stuff before?
