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.
