Is it reasonable to use power buffing tools (such as the dremel buffing wheels) on ploymer clay? I've wet sanded and sanded and *sanded* and I'm not seeing any difference. I also have a real aversion to the sound and feel of sanding, wet or not, so a power tool would be a blessing. If you've had this work, would you tell me a bit about how you use it?

I tried the Dremel buffing disk, and while it had an effect, it seemed minimal. I think I wasn't at that stage yet - I probably needed something courser first, but the sanding wheels scratch the clay. Any help is appreciated!
