I have a small Casita fiberglass camper that someone had brushed white FlexSeal (rubber seal) on the bare fiberglass interior walls to seal some leaks. Now I need to adhere carpet to the walls for insulation. I’ve tried 3M 90 adhesive spray and doesn’t stick. What product will stick to this FlexSeal rubber paint that’s been brushed on my fiberglass walls?
Please advise
