Mine has the small platform on front, so the diamond plate seems like a good idea to me. If you just want the cosmetic look, go to your local sign supplier and get some diamond plate adhesive backed Mylar film. It looks nice and will likely be easier to clean. It's a good place to check out for other thin sheet material, in case you don't like the mylar. they will also cut to size. Proveer is my go to supplier, if you can't find them look under sign suppliers, or plastics.
