Does the epoxy need to be scuffed before a bed liner will stick to it? Ive decided to spray the inner fenders before I weld them in, the epoxy was sprayed over a week ago.
U-POL’s Truck Bed Liner can be applied to most original manufacturers finishes.
The surface should be lightly scuffed, and free from dirt and rust. For best results bare metal should be treated with a suitable etch primer e.g. U-POL ACID#8 (UP0776/ UP0741)

"It just depends on the type. Epoxy, you do not need an acid etch and it could react poorly in terms of adhesion. Our is a urethane, so it has no anti-rust properties. A metal etch is needed, not suggested or recommended. But with epoxy you lose ability to hold gloss and color. Also non repairable.
While using any metal etch, always make sure to watch dry times/cure times. Like a solvent, the acid needs to evaporate. Nothing will stick while the acid is evaporating.
Hope this answers the question. I assure an acid etch is necessary and is chemically compliant"
