  • Patent number: 6298518
    Abstract: A buffing pad assembly is provided for buffing, polishing or otherwise finishing a painted surface. The buffing pad assembly includes a rigid backing mount, a back-up pad affixed to the backing mount, and a buffing pad removably attached to the back-up pad by way of fastening material provided on the back-up pad and the buffing pad. The buffing pad has a number of channels extending completely through the pad to facilitate dissipation of heat generated by friction during use of the buffing pad. The back-up pad and the fastening material are designed to accommodate the heat dissipation channels in the buffing pad so that the channels are substantially unobstructed. Additionally, a centering system is provided on the buffing pad assembly to facilitate alignment of the buffing pad during use.
