Yes, the last lens boards I made I had powder coated. These turned out
very nice!

Brass plates pretty well. I don't believe that aluminum is a particularly
good candidate for plating though. I did try copper plating some aluminum
heat sink blocks for a radiometer system I was building once. It works,
kind of, but the copper didn't stick terribly well. I think the
propensity of the aluminum to surface oxidize tended to undercut the
plating. There may be a way, but I didn't find it. Using a nickel
passivation layer first maybe? I also can't think of any aluminum plated
parts that I've seen either.
