I tumbled my brass in my vibratory tumbler and the brass came out with smears of a tar like substance!?!?
My guess is that the case polish I added mixed with the soot/dirt and created a tar. It is now dried on the bowl of my tumbler and required a combination of mineral spirits and a scraper to get it out.
Has anyone else experienced this?
Is this natures way of saying to change the tumbling media? Or, to not use case polish? Or, ...????
