Re: 3m Clear Film paint protection removal Reply #20 – December 15, 2015, 06:10:40 pm I tried everything. Finally resorted to heat gun on low and plastic razor blades. Took forever, but got the film off. Removal of the adhesive was equally trying. Tried 3M and several other removers. Found that lacquer thinner in small areas at a time worked best. Took a long time but results were worth it. Quote Selected
