Thanks! Looks like it was used as a coating in this case as some of the hardware (strainer, tension rods and swivel nuts) are steel while the lug posts and caps are brass. If the bare metal was showing through, it would be all different colors. Instead, all of it is has the silver-ish aluminum coating now.
I know the cost of replating but that may be the best option here. I got a reasonable deal on the drum and I would love to see it returned to original condition instead of leaving it in this state with aluminum oxide coating all over the hardware. I'm going to think about it for a while.
