Don,
Just the square 5x5 cover plate that you'd cover the electrical connections with. It is galvanized and I hadn't thought of that initially. The guy who cut and ground it for me builds bikes for a living and he didn't mention it, not that that is any indication, but I didn't get a "whoa, dude, you can't use this", from him. You're right...guess we wait and see. I used Rustoleum's Professional sandable primer and will be finishing it with their satin black. That stuff is supposed stick to anything. Most of it won't even be exposed, so...maybe I'll be in luck.
Tad
