no no no...this is what me and pretty much all the locals do around my neck of the woods ..go to walmart in the "car/truck paint" section theirs stuff made by plastic coat its in a red can and it called "SPRAY ON TRUCK BEDLINER" spray one normal coat then hit it with a hair dryer for a c few mins. and then spray on a "heavy" coat and after it dries over it night its harder then a virgin on his wedding night....never worry about paint flaking or cracking again and makes your body SUPPPPERRR STRONNGGG and it dont weigh very much eighter as if a few oz. are going to kill ya?
