Polishes finishes to a mirror like surface. Creates a ultra smooth, polished finish. J. E. Moser"s® natural abrasive products, used along with paraffin oil for a lubricant and felt blocks to rub, are excellent choices for rubbing out wood finishes. We recommend beginning with coarse (2f) then fine (4f) pumice stone for achieving a universal medium gloss sheen. Rottenstone is used following fine pumice for achieving a high gloss: For best results use a clean felt block or pad when changing between pumice and rottenstone. USA.
