  • Patent number: 6124044
    Abstract: 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.

  • Patent number: 6117485
    Abstract: 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.

  • Patent number: 5866199
    Abstract: 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.

  • Patent number: 5603992
    Abstract: 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.

  • Patent number: 5567756
    Abstract: A composition is provided for protecting exterior surfaces of automobiles and other products against abrasive dust, acid rain, etc. The composition is applied as a mixture of water solubilized acrylic acid copolymer, pH-neutral acrylic copolymer, alkyl alcohol, surfactant, and water. The composition dries on the exterior surface to form a tough flexible coating that can be removed by an alkaline aqueous detergent solution.
