Sedoso XRS: Pumice Polishing Grit
Ultrafine Pumice Polishing Grit for rubbing up the final finish coat to polish level desired. Loose pumice powder is applied and worked using a rubbing cloth, felt pad, or rotary buffer and a rubbing oil lubricant. Sedoso XRS has the foamed-stone friability and particle-size equivalence of a typical rottenstone powdered polish, thus the XRS designation. Use only on fully cured (hardened) finishes.
