I have a LOT of extra asphalt coating sitting around, can't remember what from But anyways, I was wondering if i could re-coat my truck's frame with that stuff. what do they use from the factory? It has a light, and i mean light coat of surface rust on it. Can i just spray over that junk?? Thanks! P.S. Anyone know of a cheap but good way to bend metal tubing? I and making a grille guard but can't afford the pro's tubing bender....
