High performance Aluminum Oxide cuts fast, lasts a long time, resists loading and leaves a consistent finish. Use these products with a soft interface pad to scuff sand before painting. Use them to remove runs, dust nibs and excess orange peel from topcoat finishes before repainting or buffing. Discs are easy to remove from backup pads. They are faster and easier to use than scuffing pads, and there's none of the dry time you get with wet sanding. Seven holes for dust free sanding. Use to level orange peel, dust nibs, and paint runs in all types of automotive paints. Recomended disc pad 05865 with soft interface pad 05777.
