Produces A Smooth, Satin Finish
Genuine, triple fine, grade 3F pumice powder produces a soft satin finish. Use to rub out a stock before finishing with rottenstone for an exceptionally smooth finish. Mixed with linseed oil it becomes a mild, fine-cutting abrasive that's easily worked over the finish using a felt pad. Use on fully dried finishes only.
