I have a set of Rene Herse cranks on one of my bikes. They came polished. After a few years of riding, however, they were mottled looking, so I pulled them off, tore them down to individual parts, and put my buffing wheel to work. It was a couple of hours of work all told, and in a few years, they needed it again. Polishing requires maintenance.
