Firm, Flexible Block Sanding A durable, easy release vinyl face of the 3M™ Stikit™ Soft Hand Block accepts 2-3/4 inch wide Stikit™ Sheet Rolls or 2-3/4 x 5 inch Stikit™ abrasive sheets. It works with the soft foam body to maintain consistent, firm contact with the sanding surface even around contours. As part of our Stikit™ system, adhesive coating abrasives adhere firmly to the vinyl face with no slipping. Yet the face also allows for the abrasive roll or sheet to be removed quickly without leaving adhesive residue. About our Stikit™ System The 3M Stikit™ system was designed for convenient changes between abrasive grades or applications. Stikit™ abrasive rolls and sheets come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to the hand block is as simple as pressing on a sticker. Yet they remove cleanly without adhesive residue left on the block. This makes for very fast change-outs, saving time, and prolongs the life of abrasives. Better Block Sanding from 3M A soft body, a firm and durable vinyl face and our Stikit™ system combine to make automotive block sanding easier, faster and more effective. The features built into our 3M™ Stikit™ Soft Hand Block afford a balanced feel that combines control, consistent facing with primed surfaces and fast, convenient sheet or roll changes – simply better block sanding for smoother auto body operations.
