What if, like mine, the repairs need to be done on the edges where it bolts to the bed? I have an idea to lay a 2x4 inside with pre-drilled holes for the bolts to run up into. It will fasten to the inside with screws. Then start laying layers of fiberglass on that(leaving the bolts holes open) until it is back to the nearly original thickness. I'm not worried about the stock weather stripping under it, I was going to use some aftermarket stripping like for garage doors instead. Does this sound insane? I can't think of any other way to replace the metal bolt strip than this. Mine is rusted beyond repair.
