In Search of High Gloss

I just purchased a vibratory tumbler. While ‘cruising the web’ I stumbled upon some comments about the tumblers. One source sent me to a gun shop. Well the gun shops in the big city were very scary even on the web. Well my search sent me to a store 200 miles away, but less than 10 miles from my sister's house. Wow, I could visit my sister and the sporting goods store. So on Monday that is exactly what I did. I was surprised at how large the tumbler was. I purchased a Lyman Turbo Tumbler. The label on the box says "gives factory brass finish; twice as other tumblers; heavy-duty, thermally protected motor; quiet running; wide stable base w/protective motor shield; includes 1200 pro plus 600 pop top bowl and lid. This is a turbo twin pack. It was the last one on the shelf and it had been opened, so there were no papers inside the box. So I am looking for all the advice I can find about using the tumbler with polymer clay. I purchased some plastic "beanie baby" pellets to try. I haven't returned home yet, so I haven't been able to try them. Last night while I was reading I read about two other methods 1. Pea gravel from Home Depot, 2. Bon Ami pot cleanser. Well I might have to experiment to see which is best. Wish me luck.
