Id watch T-Cut as It does the trick!
I wiped the paint and excess off as soon as i saw it. It was just the oily residue left on the car.. so T-Cut worked out a charm!!
I agree with lump though. If the paint is left on for a few days or so, Iw will cause alot of damage.. but for me luckily I removed the majority of it.. as I saw it when leaving the site... The briefly washed the patches with water and car soap... The few days later remember-then started this thread. Tried T-Cut and the car looks better than before!
