    I’m fine tuning my EM pop bumpers, including getting the 1960s era rings all smooth and shiny.

    They look very good, but not as good as the finish on the new ring I got as a spare, just in case.

    I’m starting polishing with green scotch brite (600 grit) to get the burrs off, then blue scotch brite (1000 grit), and finishing with Mothers Mag & Aluminum polish.

    Am I missing a step? Is there simply a limit to how good I can get it by hand?

    Try using the tumbler with walnut shells and flitz. Run it for several days. It works pretty well.

    If you don’t have a tumbler, go with higher grit before the Mother’s. 1000, 1500, 2000, mother’s = super shine! Wet and dry sandpaper is your friend.

    Buffing wheel

    A tumbler with Mothers Mag polish will make them mirrors if you have one. As a last resort I agree a buffing wheel is great just be Careful. Since you only have a small run of parts consider using a Dremel mini buffing wheel at high speed and Mothers and you should get them looking pretty good.

    First I clean the gunk off of them with 99% alcohol. Then wash with a spray of Mean Green and rinse & dry. Then I hand polish with SimiChrome. Comes out very nice looking.
