The large dimension of the cells on these coarse pads dissipates any heat build-up, allowing the compounds applied to work at optimum levels. The oscillating movement of RUPES BigFoot systems provide a perfect partner for the porous structure of these pads. The abrasive compound used with these pads are not retained inside the sponge but is continuously applied to the work surface, providing a constant layer of lubricated abrasive between the surface and the foam polishing pad. The use of the RUPES Zephir abrasive compound is recommended.
