A complete system for buffing and polishing resins that will give a quick, flawless finish to any cast blocks, especially to Clear Casting Resin which has articles embedded or encapsulated. Rub down the block with 120 grit and 320 grit wet and dry paper (use wet), washing the block in running water after each grade. Then use the red buffing compo on a buffing mop to polish off any remaining scratches or marks on the surface of the block. Clean off any remaining red compo and then repeat using the white polishing compo on a polishing mop to produce a highly polished surface. The mops can be used in an electric drill clamped on a bench mounting. By using the steel arbor, both mops are easily and quickly changed by simply screwing on or off. The mops have a centre hole for mounting on the steel arbor. Always use goggles and a dust mask when polishing. The polishing process is described in more detail in the Polyester Resin Technical Booklet (Code: 990-505).
