Rick:
I think your wife was spot on!

 

When she married me? That's what I keep telling her.
Looks like I'm going with Rustoleum enamel in aluminum color, clean the current surface, clean metal primer then thin multiple top coats. Will mask and use a high density foam roller.
We shall see but its simple, easy to execute, easy to touch up and to put something else on top if I don't like it.
