Being alloy, the best way to clean them up is to sbrasive blast the ally, then coat with primer asap. Two pack paints will give the shiniest results if that is what you want. My powder coating is at 95% gloss anyhow, so I am hsppy with that. My bike is also not a concourse bike, I intend to just make it nice, that way zi can enjoy riding it without worrying about a small mark ruining the bike. Been there , done that, never again, too much of a pain to enjoy the bikes as they are meant to be used.
