BERNARD LABORATORIES INC. - Rooster Labs Cartridge Polish

Purchased this with untreated media and it works as good as the treated media I've used before. Since this polish was 'fresh' I did notice that it cleaned faster. Will continue to use this as long as media+polish cost is less than treated media.

This stuff is worth way more than it costs to me. I still ultrasonic my brass to remove residue, lube, trim and resize then throw them in the tumber with clean corn media with this stuff polishes the cases in about 15 minutes. The brass comes out with a high luster, looking better than factory brass and does not corrode from skin oils after handling. There is a definite film on the brass and this is the best additive I have used yet. The tumbling time is cut down substantially and there is no worry about handling the brass for charging and seating. Just make sure you run the tumbler for a few minutes without brass after adding this additive; if not, the media will stick inside the cases. Don't ask me how I know this...
