Backup pads and disc holders are used on power tools to drive coated abrasive and surface conditioning discs or sheets. This double sided pad attaches to the Hookit™ skirt on our 3M™ 3125 nib sander with a brushed nylon loop. The pad has a blue vinyl face with a white nylon loop on the back to hold the 1-1/4 in PSA backed 3M™ 466LA abrasive discs. The small, 1-1/4 in Dia head size of the 3125 sander can help you see the exact point to sand and produces a smaller area to buff out than conventional tools. 3M™ Finesse-it™ products are a line of specially engineered abrasives, compounds, polishes and buffing pads to be 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.
