<p>A rotary foam buffing pad (10) is provided with a concave working face which allows the operator to provide true graduated surface contact in applying polish, buffing or glazing compounds, while containing the polishing compound against centrifugal force which would otherwise result in splattering of the compound. The manner in which the concave working face (17) is formed and in which the edge face (20) is formed and dressed results in dynamic balancing of the pad and reducing vibration and operator fatigue. The working surface forming and pad finishing operations further provide a velvetized texture to the pad working surfaces (17) which further enhances the polishing or finishing process.</p> |
