Patent number: 7252853Abstract: A vehicle masking material and method of use. The masking material in one embodiment includes polyvinyl alcohol, ethyl alcohol, glycerine or triethylene glycol, a surfactant, and water. The masking material is applied to a surface which is to be protected from paint overspray or other mechanical process, allowed to dry, and paint is applied. After drying of the paint, the masking material is removed by peeling or water washing.Type: GrantFiled: July 2, 2002Date of Patent: August 7, 2007Assignee: Cal-West Equipment Company, Inc.Inventors: Edward W Woodhall, Nicholas Kondrats

Patent number: 6124044Abstract: Methods are provided for protecting exterior surfaces of automobiles and other products, or components of products, against abrasion, abrasive dust, water, acid rain, etc. The methods involve applying to a surface a protective coating composition comprising an emulsion selected from the group consisting of a vinyl-acrylic copolymer emulsion and a vinyl acetate-ethylene emulsion. The emulsion is dried to form a water-resistant protective coating that can be removed from the underlying surface by peeling when no longer desired.Type: GrantFiled: October 27, 1995Date of Patent: September 26, 2000Assignee: Cal-West Equipment Company, Inc.Inventor: Ronald Swidler

Patent number: 6117485Abstract: A vehicle masking material and method of use. The masking material in one embodiment includes a dextrin, a plasticizer, and water. The masking material may additionally include a surfactant. The masking material is applied to a surface which is to be protected from paint overspray or other coating processes, allowed to dry, and the surface is coated (e.g. with paint). After drying of the paint, or other coating, the masking material is removed by water washing.Type: GrantFiled: July 24, 1998Date of Patent: September 12, 2000Assignee: Cal-West Equipment Company, Inc.Inventors: Edward W. Woodhall, Ronald Swidler

Patent number: 5866199Abstract: This invention provides for primer/masking compositions that have differential adhesion properties for glass-like and non-glass surfaces. The compositions are used in a method of applying a finish to a non-glass surface which resides in proximity to a glass-like surface without substantially overcoating the glass-like surface. The method involves applying to the glass-like surface a primer/masking composition comprising a vinyl chloride copolymer emulsion, a coalescer, and a surfactant; applying the finish to the non-glass surface, and removing the primer/masking composition from said glass-like surface.Type: GrantFiled: October 31, 1995Date of Patent: February 2, 1999Assignee: Cal-West Equipment Company, Inc.Inventors: Ronald Swidler, Edward W. Woodhall

Patent number: 5690539Abstract: 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.Type: GrantFiled: August 7, 1995Date of Patent: November 25, 1997Assignee: Cal-West Equipment Company Inc.Inventors: Ronald Swidler, Edward W. Woodhall

Patent number: 5603992Abstract: This invention provides methods and compositions for the temporary protection of activated plastic surfaces. The methods involve application of protective coating compositions to activated surfaces thereby protecting the surfaces from oxidation, soiling and mechanical damage. The coatings may be easily washed off leaving a clean activated surface suitable for overcoating.Type: GrantFiled: April 18, 1995Date of Patent: February 18, 1997Assignee: Cal West Equipment Company, Inc.Inventors: Edward W. Woodhall, Ronald Swidler
