Canvas polishing pads have a rigid spin-on plastic back plate with 1/4"-20 thread bolt. A 1/4" inch thick foam rubber backing ensures the pad conforms to the shape of your stones. Canvas pads may be used with diamond compound or other lapidary polishes such as tin oxide or cerium oxide. When using diamond compound, use a silicone lubricant such as Lapcraft Microsol Silicone Extender Fluid.
