Refinishing cranks?
so i've had a set of dura ace 7701's for a while, and they've been beat up and rubbed up(dura ace logo is no longer there). I was thinking about polishing them up, but im working on a new build where the parts are mostly black, and i was wondering if there was a safe way to powder or paint the cranks? or should i just polish them up, and have polished cranks but black everything else?
