For a consistent finish, use 3M™ Hookit™ Purple Finishing Film Abrasive Disc 260L – our discs with a fast‐cutting, long‐lasting aluminium oxide mineral abrasive. Use them to sand top coat for blending, and for removing 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 they are quicker and cleaner than wet sanding. Use for scuffing the blend area before painting.
