Abstract
This invention provides for provides for abrasive compositions and methods of use of these compositions for the preparation of surfaces for the application of various coatings such as paints, lacquers and varnishes. The abrasive compositions of this invention provide rapid cleaning and dulling of the underlying surface rendering it suitable for the application of paints or other finishes.
