I couldn't get the chainring I wanted for one of my projects in silver and ended up having to get black. I was going to live with it black but wondered if I could sand the anodizing off or use some kind of chemical and how hard that would be. I'd imagine bare aluminum would need polished every so often to keep looking nice, but on a classic build I'd much rather have a silver look to match the rest of the silver components. Will be going on a DA7800 (silver) crank upgrade for my '88 Tempo.
