  • Patent number: 4899414
    Abstract: A polished surface protective sleeve that is used for covering the electrical cord of a car wax polishing and buffing machine. The protective sleeve is formed of an elongated tubular member having an internal diameter greater than the outside diameter of the electrical cord. The outer surface of the tubular member is entirely covered by a layer of soft unabrasive material. The protective sleeve has been designed to eliminate the situation when the electrical cord is dragged across a polished car surface while buffing an adjacent area.
