Each pad has Velcro® brand hook and loop fasteners to secure the pad to a 2 7/8 or 3 inch backing plate.Lake Country’s flexible backing plates each have a flexible beveled edge to prevent contact with the glass during operation. The 3 Inch Glass Cutting Pads can be used with your dual action or circular polisher. Work in a small area using a back and forth motion. Keep the glass wet while you work by misting it with water. For glass correction, use a designated glass polish, such as CarPro CeriGlass. Paint polishes can have fillers or oils that will make the glass tough to clean. CarPro CeriGlass is water-based and wipes away clean. | The 3 inch Glass Cutting Pads can be used with a rotary polisher, like the FLEX L3403, equipped with a 2 7/8 inch backing plate. |
