They are actually pretty durable Kentos... and when you rinse them off under the tap they clean up pretty good. A lot more durable than a piece of sandpaper that size.

Hmmmmmmm....I may break down and try some.

They aren't going to replace your sandpaper, but they compliment it very nicely for the finer end of the polishing.
