I have read several posts on adding Nu Finish Car Polish to the fine crushed walnut shells in a vibratory tumbler. Question: How much Nu Finish per hopper and how often to add more?

I usually use Dillon Rapid Polish to clean & polish cases.
3 or 4 cap fulls, per instructions. ( less than a half a shot glass)
But if I run out , I've used Nu Finish cut 25% to 50% with odorless mineral spirits. Shake well.
I put less than half a shot glass in with the walnut hulls, let it mix for about 5 mins. then add the brass.
If you throw in the brass to soon before it has mixed, it can get inside the brass and cause some additional work getting it out .
Let it run for about 2 or so hours. It does a good job of cleaning & ploishing cases.
Don't use anything with ammonia in it !!

You really need to try the stainless media.
It makes old dirty brass look new, and never needs replacing
like the other media.

For anything larger than 9mm cases, I add 1 cap of mineral spirits, run the tumbler for 2 minutes, add 1 cap of Nu Finish or a healthy squirt of Flitz media additive, run 1 minute, add brass, tumble 4-6 hours, remove and it looks like new. As long as the media stays wet, I don't add mineral spirits and the brass stays dust free. I add 1/2 cap of polish every load and I pre wash muddy or gritty brass in hot soapy water prior to tumbling. 9mm and smaller will cake with media.
I've always used Brasso in walnut media. I add a teaspoon full every couple of runs. Been doing this for about 40 years. 1 can lasts a long time. But, I never entered any brass in a beauty contest. Functionality and longevity have always been the criteria. I've reloaded a lot of really old (1870's) and rare brass as well as the thousands of rounds run through full auto guns with no problems or complaints from onlookers.
Well, I took the advice (mostly) and went to Harbor freight and purchased the 5# vibrator tumbler for $55 and 25 lbs of fine walnut media for $24. Then to Wal-Mart for the Nu-Finish for $7.50. I had some old 38 spl brass that was military ball from 1966 that was super dark and dull.
I put 2 1/2 lbs of the walnut and one cap of Nu-Finish and 1/2 drier towel. I ran it 10 minutes then added 250 rounds of the old brass. I checked it after 2 hours and it looked really bright and clean. I decided to let it go for 2 more hours to see what would happen. 4 Hours total and I really couldn't see much improvement over the first 2 hours. It really shines!
I removed the brass and shook it out over a bucket with a large strainer and then packaged it.
I added 1/2 cap of Nu-Finish and 1/2 cap of mineral spirits and after operating for 5 minutes I added another 250 rounds of brass.
Thanks for all of the advice. Y'all are great!

Just remember that if you are using part of a dryer sheet (which I do), make it a used one. New dryer sheets can leave residue on your brass.

Instead of a used dryer sheet I use about 1/4 of a sheet of the blue paper shop towels that I buy at Costco.
Works good and always on hand.
Take care R.J.

Two things... Have momma save the used dryer sheets and cut them in four strips, before you toss them in the tumbler. Also, somebody here turned me onto the crushed walnut shells sold in pet stores to line cages. Very cheap and works well, and because it's cheap you can change it out more often. To the original question, Nu Finish works great.

Nu Finish is not for cleaning brass, rather it leaves a fine wax on the brass to keep if from tarnishing
That's what I do. And I throw in 1/2 of a used dryer sheet (that's how my wife uses them - 1/2 sheet at time)...
