I use 3M diapads to finish the bottoms of pots . . . here is one sourcehttp://www.toolocity...shing-pads.aspx (It looks like they are out of some grit blocks now)
Basically, a version of "wax on, wax off". I dip the sanding blocks in water and polish away. I recommend 100 and 200 grit blocks for most items, although I do have a couple of 400 grit for making a surface really smooth. I use these on Highwater's Little Loafers and Red Rock, Standard 266, 306, and 381, and Laguna Dark Brown and Soldate 60. Those run the gamut from smooth clay to groggy clay. Do not recommend using them for dry sanding; too much dust. And, they clean up bisque really nice, too.
Ty for the link super fast shipping
They work amazingly well, much better than any of the sandpaper/pads I've tried.
Lowest I got was 100, wish I would have gotten one more coarse
Pads are much stiffer than I expected.
I've only had them for a day, are you getting good life span on yours? Have you had issue with them getting clogged?
the bottoms get super smooth, so no scratching the good furniture
They work so well that they create somewhat of a knife edge with the newly smoothed bottom, but easily remedied with same pad.
