We found a zep degreaser product that is amazing as an adhesive remover. The pros are it is a gel, so it does not run on a vertical surface, it just stays there and dissolves the adhesive almost but not quit as good as rapid remover. I get it by the case and it sprays on and is like jelly. The cons are it's kinda hard to get for some folks, kinda pricey, is flammable and is very greasy and needs to be cleaned after with alcohol, and you have to be careful on some sufaces as it is very strong and can cause damage if left on too long. We have both and use this zep stuff 5 times more often because it does not evaporate or run down the side of a vehicle. By the way as an engine degreaser it is far better than the spray on foaming stuff too.
