I have never used a tumbler, all I know is u put media inside it such as crushed walnut shells or corn cob and it polishes. Know i did see in a thread Glen puts Turtle Wax rubbing compound in with the media also, it does not remove pittin from rust either. I guess what Im getting at is what kind of results do you get from useing the tumbler? Will it remove the black stain or tarnish from metal ? What kind of results could I expect from useing one?
Thanks Tony
