Claim:
A method of abrading a surface of a workpiece, said method comprising: a. providing an abrasive product comprising: i. a flexible backing having a first surface bearing a cured primer coating, an opposite second surface and opposite ends; and ii. a plurality of shaped structures each structure having a distal end bearing a shaped pattern spaced from said backing and an attachment end attached to the primer coating on the backing, said shaped structures comprising a three dimensional structure comprising abrasive particles locally bonded together by a continuous, cured organic particulate binder, wherein the three dimensional structure defines a network of interconnected voids; b. contacting the surface of the workpiece with the distal ends of the shaped structures; and c. relatively moving at least one of said workpiece or said abrasive product while providing sufficient force between the workpiece surface and the distal ends of the shaped structures of the abrasive product to abrade and/or otherwise modify the surface.
