i'm in the middle of restoring this cool 80s bike, polished up the aluminum parts to a shine, got rid of rust, but now I'm scratching my head about protecting them from more oxidation.
i was eyeing aluminum anodizing, but since these parts are old and might be a mix of materials, it feels kinda risky. Anybody else run into this? What's the secret sauce for keeping that vintage aluminum looking fresh without taking a gamble on anodizing?
