I've really wondered how this Appliance Epoxy stuff would hold up. It comes in both spray and cans.
Krylon Appliance Epoxy Paint White, Size: 16 oz, Net Wt: 12.5 oz
I used it on the plywood walls of my head instead of putting white veneer back on them. It's lasted three years so far. I doubt it has any UV protection in it, though.
