What would be the best tumbling media for a matte/frosted finish on aluminum? I've made some .22 loading blocks for giveaway to my 4H shooters that I coach. They are made out of old aluminum barstock with quite a few dings and dents. Polishing doesn't seem to help and only brings out the imperfections that I want to hide. I plan to tumble them and see how they look.
I don't have a tumbler yet and have never used one. Your thoughts for a first-timer looking for a matte finish on aluminum?
