  • Sanding and polishing systems
    Patent number: 6520846

  • Compounding elements and use thereof
    Patent number: 5846123
    Abstract: A compounding element for use with a rubbing compound in the finishing of a working surface. The compounding element has a buffing surface and a resiliently deformable skirt around the perimeter of the buffing surface and projecting beyond the buffing surface. In use, application of pressure to the compounding element on a working surface causes deformation of the skirt so that the buffing surface contacts the working surface and the skirt restricts slinging of the rubbing compounds.
