BACKING PAD FOR FOAM POLISHING PADS The RUPES backing pad is essential for the stability of the BigFoot System. Manufactured from expanded polyurethane, it is particularly resistant to mechanical stresses and together with the BigFoot foam polishing pad reduces vibration to a minimum. The special perforations in the pad are designed to create an air flow that helps to dissipate any heat generated by the polishing action. The material used for the manufacture of the velcro provides an effective anchor for the foam polishing pad.
