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?
