Well a heat gun helps a lot to put it on, so wouldn't it make sense that it would also help to take it off? I don't know from experience though, I've never had to, or known anyone, that had to take it off. Not if it would leave any residue from the tar either though, or how much a PITA it would be to take off, but I'm sure you could find a product at Wal-Mart or a hobby store that would help with that residue. Maybe warming KY?
