it's going to suck, a lot. I'd probably see how it reacted to being sanded on with some 80 grit on a da if it's thin, and I'd try to to at it with a heat gun and scraper if it's thick. it's going to be incredibly unpleasant regardless. be very careful with the heat gun/scraper combo you can definitely do some damage with this setup. use no more heat than is necessary to soften the Bedliner and use a blunt edged scraper as to gouge the surface you're trying to save the least amount possible. post up some pics so we can see what you're working with.So the PO of my 1972 FJ40 bed lined the topside of the roof cap, it’s rough and yellowed. Any ideas to get the Bed liner off so I can restore?
