any opinnions on either durabak or herculiner its time to coat the inside of my body and 500 bucks at the local paint shop is to steep .the durabak seems to have the closest color match ,red,since mine is red.what did you all do about floor plugs and bolt holes for seats and belts etc, i guess just plug the holes with tape but does that leave any kind of ridge or blotch when you remove the tape ,any help?
