Is it all right to strip and then anodize (at a shop, I suppose?) aluminum cranks?
I'm trying to build a bike and I saw second-hand cranks on eBay. They look like they're fine except for the scratches/abrasions they have. They're fairly cheap too compared to new old stocks so I'm wondering if it would be a good buy if I can restore them to look brand new again.
So would stripping, sanding, anodizing, etc. the cranks have any negative effect on them?
