Turtle Wax Rubbing Compound in a tumbler

I use Nufinish in my media for a good shine & to reduce tarnishing

I also add a dash of mineral spirits to the mix

I see no need to use an additional abrasive to my media. I have found some different media to be used for different needs; for heavily tarnished brass or rusty tools/parts, I use Harbor Freight hard resin media. For "normal" brass tumbling I add mebbe 10-20% hard resin to corn cob blast media plus a tad of auto wax (mfg doesn't matter, but no rubbing compound). For the brass I want shiny (30-06 and 45 ACP) I use straight corn cob blast media (not pet poop catcher) with a bit of auto wax (I have even tried museum wax, carnauba wax, melted candle wax, furniture polish (Pledge) and maybe a couple more, most failed). I just wanted a bit of tarnish protection, no chemical or abrasive action wanted...

Same here.

I use Zilla lizard stuff for media with whatever car wax I pick up cheap. Works for me.
