I've been using a wet rotary tumbler for about a year. Love it. Way better than vibratory. I noticed something today. I was working a large batch of 30-30. I had to run it in two batches. My first batch came out shiny and bright. Second came out somewhat dull. Everything was identical, other than I don't measure my LemiShine or the ArmorAll Wash n' Wax I use. Is there a correct amount you all have found? I use the Frankfort Arsenal Lite.
