The 3M™ Finesse-it™ contact disc pad is used to drive 3M™ Finesse-it™ buffing or polishing pads and Hookit™ discs. 3M™ Finesse-it™ contact disc pad is part of the 3M™ Finesse-it™ paint repair system. It is 1 in THK with a 5/8-11 internal thread and designed to be used with 5-1/4 in buff pads or 5 in Hookit™ abrasive discs. Use this soft density disc pad with a rotary sander or right angle grinder at a maximum rpm of 7000. Thickness and compressibility allows for excellent contouring of the pad to follow panel shapes in buffing and polishing applications, but also "cushions the blow" when sanding metal with fine grade abrasives. Backup pads support the disc or buff pad and evenly distribute pressure to the workpiece. For best performance and durability, it is important that the appropriate backup pad be selected. 3M™ disc pads are designed to create the lowest vibration and best sanding performance while using 3M™ power tool and abrasive accessories. 3M™ Finesse-it™ products are specially engineered abrasives, compounds, polishes and buffing pads used on OEM and baked refinish paints to remove defects, sand scratches or swirl marks on a variety of painted surfaces. Finesse-it™ products are an integral part of a 3M™ recommended buffing system for repairing surface defects to clear coats, lacquered wood, solid surfaces, gelcoat powder coat, industrial paint, acrylic and glass.
