    Hi,
    The “before” looks exactly like mine. How did you polish it? did the rings need to be re-coated after all the flakes were buffed off? How about the arms? The original finish looked to be a coating of some kind.
    Thakns!

    First you have to use compressor with dust/sand blow and after polishing the arms or chainrings.
    don’t need to recoeted them just polishing.. that’s the secret.
