Iv been experimenting with autosol metal polish it’s used for polishing chrome brass copper ect, I polished a piece of 308 brass using a rag, when done this way it brings brass cases to a very high luster so I though id add some to my tumbler and see what happened. The problem is it’s a fairly thick paste so in a old cup and put it in the microwave for 5 seconds and it melted into a very thin cream constancy perfect for poring, with the tumbler and media turning over I poured in small amounts around the bowl, it blended in nicely after about 5 min,
I dumped in some lightly tarnished brass and left for 30 min.
when i stopped the tumbler the brass had a very light coating on it, similar to what new media does to brass.
So I got a piece of rag and gave it a quick buff and it took on a bright luster just as good as the piece I polished earlier in fact I could not tell the two apart.
