Hey guys, new here, but I have been shooting for as long as I can remember and started reloading about a year ago. Anywho, the only cases that I have reloaded so far have been the stuff that I shot and pick up after myself, the majority of those cases were store bought so that I could get a decent brass inventory up. I recently obtained a metric butt ton of DoD once fired 9mm from a friend, most of which was shot and swept up that day. However, I have run across a few really old and tarnished pieces of brass whose headstamp is about 4-5 years older than the rest of them. My question to you is, how do you get these really old cases polished up and new looking. I have a Frankford Arsenal tumbler that has been really good to me. I use walnut media and works amazingly well on all the new, once fired stuff, but after even a few loads, I keep throwing the really old stuff in there to see if they will get better, but to no avail. Any tips on how to pretty them up?
Ok, next question, say I wanted to seal my primers to make them more weather resistant. Does anyone sell primer sealant or can I use nail polish or something similar? Thanks for your help.
