Dissimilar metals = corrosion through electrolysis , just something like 3M 471 vinyl tape will help..I went back w wood n sealed the h..ll out of it.. Covered the area around the dump with plastic coating ( like rhino liner paint) from NAPA. Lots of examples out there in many colors. Worked well. I coated the bottom side of the bays with a asphalt based sealer (undercoat) I'm sure what ever you choose will work out just fine!
