I found this to be an EXTREMELY informative thread and thought this would help out a lot of people here.
Over 30 different products were tested. It seems like the best results were from Eezox with Tri Flo, PL10, Corrosion X and Weapon Shield CLP coming in right behind. Now some of these are not lubricants, just made for rust prevention. It’s amazing though how downright horrible some of the popular products faired in the testing.
Go to the thread linked above to read more about how he ran the experiment. But to summarize he sprayed the samples with a water/salt mix (to simulate a worse-case scenario) and even left the samples in the rain a few times...
Here is the final picture after about a week. There are several close-up pics in the thread on m4carbine.net.

Make it right - EVERY time!

I have the same tumbler, it works great. It comes with a sort of slotted bowl for media separation, but I recommend a case media separator if you will be polishing a lot of brass.
How is this for cleaning brass? This really is a rabbit hole.
