Just a thought, but since a mat will just hold water and mud underneath to start rust on the newly painted floor panels, how about truck bedliner coating. That way the moisture and mud don't start the rusting process over again.@tompands I haven't decided. The original is all destroyed so I would have to either buy a replacement from Caterpillar or make one myself. I would expect it to be very costly from Cat.
Any suggestions for material to make one out of?
