Not sure if it's the right section but put it here for maximum exposure. I'm helping a mate remove some vinyl/decals off his campervan that need to be taken off before it goes in to be resprayed. At the moment we're using a heat gun to remove the actual vinyl but whats the best/easiest way to remove the adhesive underneath? At the moment we're using white spirit and a scourer which works but its hard work. Any ideas?
