Abstract
A buffing pad that includes a substantially conventional buffing pad made of tufted wool that includes a backing plate and a central hub for attachment to the shaft of a rotary power buffer. The tufts or strands of wool are of a first and substantially equal length and of a substantially uniform color. The pad also carries a plurality of shorter tufts of wool or other fiber of a contrasting color. When the pad is relatively new, the shorter tufts are not normally visible as they are hidden by the longer tufts. As the pad becomes worn, however, the longer tufts become shorter and matted down thereby exposing the shorter tufts. The appearance of the contrasting color of the shorter tufts is an indicator that the pad is worn and should be replaced.
