A good exterior grade plywood and seal it with an epoxy like West Systems is the way to go. Use the lowest viscosity stuff and build up multiple thin coats. Thicker stuff doesn't penetrate as well. But it also needs to be covered with paint, carpet, EVA, or whatever because on its own you'll abrade right through it.</p></blockquote><p></p>
