3M Hookit Soft Interface Pad is a soft density foam pad that adds cushion and conformability to 3M Hookit back-up pads for auto body sanding applications requiring precision across uneven surfaces. It increases abrasive cut and enables more consistent contact of abrasive discs around surface contours. The pad allows closer sanding to edges for smoother, more refined finishes.Use 3M Hookit Soft Interface Pad as cushion between a 3M Hookit Back-Up Pad and a 3M Hookit Abrasive Disc. Our 3M Hookit Soft Interface Pad optimizes conformability during the auto body sanding process. The pad features soft yet durable 13 mm (1/2-inch) foam construction that allows technicians to maintain consistent abrasive contact when following contours and to sand closer to edges without burning through. The pad contains a pattern of uniquely designed holes which equalize air flow, providing air distribution across the entire disc. This allows dust to be pulled through and away from the disc and the sanding surface, improving the work environment and prolonging disc life. It can be removed cleanly and easily, and be used again and again.
