A high efficiency film-forming diamond compound compatible with BOTH oil or water-based extenders. Smooth spreading, fast polishing, for use even on ceramic laps! It tames the beast. The regular blocky material (PANDMD or PANCUT series) is the improved form of the regular DIASTIK, which was available in waterbased or oilbased formulations. The PANPCD products are the premium Polycrystalline diamond which offers up to three times the speed, and finer finishes. Made in Massachusetts, USA
