[0074] To produce various surface protective coatings, of this invention, components (as shown in Table 1 and Table 2) were combined at room temperature and at atmospheric pressure by slow stirring to form the various surface protective masking compositions. The homogeneous masking compositions were then adjusted to 8.5-9.5 by the addition of sodium hydroxide.

Abstract

This invention provides a masking material that can be used to protect an underling surface (e.g. an automobile surface) during an overcoating (e.g. painting) operation. The masking material in one embodiment includes a thickener and a pH control agent and water. The masking material can be applied to a surface that is to be protected from paint overspray or other coating processes, allowed to dry, and the surface then coated (e.g. with paint). After drying of the paint, or other coating, the masking material can removed by water washing.
