The large dimension of the Rupes Blue Foam Compounding Pad cells dissipates any heat build-up, allowing the compounds to work at optimum levels.The oscillating movement of the BigFoot systems is a perfect partner for the porous structure. The abrasive compound is 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 compounding pad.
