heard alot about herculiner, but does anybody know anything about the rust-oleum (spelling?) roll on liner? herculiner is around 80-90 dollars around here rust-oleum road warrior is cheaper for basically the same thing. it comes as a kit, (roller,brush,gloves,mixer,sanding pad etc.) has anyone ever seen this? I bought some from a guy, and used it it seems great but i have not had it on that long but i know you almost have to use a chisel to dent scratch the stuff. also if you have seen it how much? not sure if i got a good deal.
