I have been using Dillon's "Rapid Polish 290" and walnut media...gets things shiny and clean pretty quickly. However, I thought I saw once that someone said they use something instead of Dillon's liquid polish. Do any of you use something that works like Rapid Polish 290, but is cheaper? I realize that it probably only leaves maybe a trace residue on the inside of the case. I wonder if using something else--if that trace would interact with the powder and cause negative results if the rounds are stored a long time.
Thanks in advance.
