The face of RUPES' wool pads are constructed of 100% natural wool fibers attached to a polyester backing material layer. Quality control of the wool is monitored through the entire manufacturing process to ensure consistency. The blue foam of the coarse wool pad is more rigid and dense which maximizes the translation of tool movement to the work surface, providing increased cutting power.
The Coarse Blue Wool Pad is constructed using two distinct fiber lengths creating a dual-density wool surface and a specific visible pattern. More than just an aesthetic detail, this configuration provides a great balance of cutting power and finishing ability when compared to traditional or single density wool pads. Coarse or medium abrasive compounds are recommended when coarse wool pads will be used with a free-spinning dual action random orbital polisher.
