i have a crankset i want to bring back to "new"...or at least, all pretty and shiny.
it appears there is some coating, which, with all the nicks and stuff is worn off in places. at first i thought i could polish out these blemishes, but now it looks as if the polishing makes it worse. it looks as if the subdued/flat greyish finish is the coating.
what is the preferred method of restoring campy strada cranks? i know this may be lacking info, i'd be happy to supply more, if i knew what that should be.
i've used a polishing wheel with an air compressor, as well as mothers mag&aluminum polish, and mothers power something squeezy aluminum polish. the polish didn't turn black on the cranks, but did on the cloth.
