Abstract: A BLOCKING TOOL A blocking tool and a method of using the blocking tool to sand a surface of a vehicle are disclosed. The blocking tool includes a first member having a length and having an outer periphery with a plurality of cuts formed therein. The plurality of cuts extend over at least about 70% of the length and each of the cuts penetrates the first member through an arc of at least about 70% of the outer periphery. The blocking tool also has a base member with a first surface, an oppositely aligned second surface, and a length. A portion of the outer periphery of the first member is secured to the first surface of the base member to form an integral blocking tool. 22 -3-4 -1-810 --- 30 38 34-),88 Fig. 1 £/10 t3 w 3 Fig. 2
