Crap! I had one but it got shot down. It was a refrence to a hot rod mag that fixed pitted/ruted floors boards with Por-15 and fiberglass. It works great together and it won't rust apart like fiberglass will after a few years. Now having said this, the rest will say, "just cut out the bad steel and weld new panels back on." Go to their web site for instructions and all their products. Its good stuff and sticks like hell to rusted metal!
Beat yall to it.
