Sponges, felts and sheepskins — the working face of a polish, and the part that decides the result more than the machine does. Sponges are colour-coded to the compound sequence, orange through blue to white, so cutting, refining and finishing each get their own. Keeping them separate matters: a trace of cutting compound in a finishing sponge puts back exactly the haze you are trying to remove. Sheepskin cuts faster than foam on heavy correction; felt is harder still. Sold singly and in packs of five, in 80 to 180 mm.
