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.
