What kind of epoxy to you recommend? I'd like to apply a coat of that spray in truck bed liner stuff you buy at walmart for like 8 bucks a can.
I agree with BusDriver. Use some PPG DP90LF(black) or DP74LF(red oxide) epoxy primer, whichever color you want it, over your floors. It's a 2 part primer, so you have to use some DP402LF catalyst too. You get these materials at a PPG auto paint supply store. Mix and spray with a spray gun...preferably a primer gun.
First though, if the new pans don't come already painted, wipe them down with some lacquer thinner to clean them. Usually, if they're bare metal, they'd have some oil on them for protection, that you need to remove with the thinner. Then sand the metal with some 80 grit. Spray the bottom side only of the new pans with the epoxy. Let dry. If they come painted already, you won't have to do that step. Then weld in your new pans. Grind down your welds to how you want them. Clean up the rest of your floor, by sanding and wirebrushing to get it as close to clean metal as you can. Wipe them down with some lacquer thinner for a final cleaning. Then spray the entire top side of floor with the epoxy primer. Once dry, spread some seam sealer(from the auto paint store), like Eagle 1 is showing, over your welded seams. You could leave it that way or spray some enamel or urethane paint over the floor for added protection. Then get some floor heat and sound insulation..the kind that you lay on top of the floor, and lay it in. Then your carpet goes over that.
I don't recommend using bed-liner.
