Well let me clarify my Bedliner in a can usage. I only use it on the steel parts. Not the plastic. I really don't know how well it would hold up on plastic either. I have found that after offroad trips my rockrails, and bumpers typically get scratched up. So I just shot it all with bedliner in a can. It really holds up very well to washing and I have not had any problems with it flaking at all. But it does get scratched off when I go dragging the truck over boulders. However I just use a wire wheel to get the rust out of the scratch and touch it up with a little and I am good to go!
