This 3M Bumpon polyurethane material allows a smoother grind and a refined polish when used with any finer grade abrasive - such as Trizact or Diamond. Mounted between the backpad and the abrasive, it gives the abrasive some extra space to "fall into" and brings vibration to a strict minimum while working. The ninja cushion is ideal for working on rounded or domed objects and is equally useful for flat surfaces.
