The professional’s choice for repairing automotive finishes
Firm Attachment
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 1-¼” PSA backed 3M 466LA abrasive discs. The small, 1¼” diameter 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.
