my hands with it the other day and it came right off. Also used it to remove plastidip from my wheels with a pressure washer and it worked incredibly well. Just soaked them with some Goo Gone and hit it with a pressure washer a few minutes later. Took a few rounds of Goo Gone + pressure washer but it beat the hell out of peeling the dip off by hand.
Compared to Goof Off I like this stuff better although like someone mentioned it does leave an oily residue whereas Goof Off just evaporates.
