Funny that you say that because I just order more sandpaper this morning to polish up my shifters. They’re meant to be shiny but both mine had been painted over. They make coatings you rub onto polished metal that’s supposed to protect it pretty well so there’s always that option. Technically the more polished metal is the harder it is to rust as far as I understand.I didn't know this, but my dad was telling me there is certain grades/alloys of stainless that will rust a little. The real question now is how long before those trim rings start to turn again? Do you know if the 4x4 floor shifter rod is chrome or stainless? That would be a cool part to polish too.
