Only ever removed one once and it was on a Mondeo it was stuck on, I will have to check with the scoob sure it's stuck on too. Managed to remove it with a heat gun not too much but keep working it off. Used (sticky stuff remover) from Halfords and lot's of elbow grease to remove the crap left over. Left to dry before using a bought rear window sticky pad also from Halfords to put it back on never came off in 2 years of ownership.
