Guys,
If you want to spend money once, listen to Marty. The Thumler's or similar rotary sealed tumblers are the best way to go for shining up brass slot car frames.
The cheap HF vibratory tumbler cannot take wet media and there is a warning in its instructions not to use ceramic media as that will destroy the bowl. They are also as nosiy as all get-out while operating.
I bought one, tired it and it has sat in my garage ever since. I then spent the money on a Thumler's AR-12 and it has tumlbed frames for seven years so far. The Media from Cabela's works great. If the water in your area is OK, then the soap they provide is also fine.
