Default Nu Finish Car polish in case tumbler

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 !!

I've seen others say they use a capful of NuFinish every few loads. Put it in and let it tumble for a few minutes before adding brass.

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

1 cap of NuFinish with walnet media makes the brass all sparkly.

I haven' tried the stainless steel media as I am too cheap to buy it and the required new tumbler.

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.

Brasso is a fine polish, but it does contain ammonia. Some folks really hate the idea of using ammonia based polish on brass cases. I don't do it based on what I have read.

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!
John

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.
