I have a huge bag of corn cob blasting media. I use it in my tumbler for brass. Problem is that it takes forever to get brass clean and it is never shiney and pretty.
My old LGS used to put something in the media to make it really work fast and make cases pretty.
Seems like it was aluminum oxide and some kind of wax. I can't remember. Any one know what it is and where to buy it?
The cob gets dirty fast. One time I threw some dirty cob out on the driveway. That night it rained. That next morning the cob looked brand new and clean. So I always wondered if I wished the cob in a bowl then stuck it in the oven to dry it, could it be reused?
What say ye?
