The surface of the pad has three circular grooves, which serve to retain and distribute polishing paste evenly over the polished item, and prevent excessive splashing.
Paste is applied by filling one, two or all three of the grooves. Starting at a slow speed, the paste is di-stributed evenly over the polished surface. Excess paste is held on the pad surface.
The grooves on the surface of the pad help save time and reduce abrasive consumption by holding it within the pad.
ALWAYS WEAR SAFETY GLASSES!
