I have a RCBS Sidewinder Tumbler. I bought some fine walnut media from Harbour Freight, and a bottle of Nu Finish. I was wondering what combination to use in the tumbler. Straight up Nu Finish, or should I add any water? Thx in advance for help.
Try the media and bit of Nu Finish.
That tumbler will probably work better with Dawn dish soap and water, though. Maybe add a tablespoon of Lemi-Shine for dingy cases.
