ABSTRACT:
A cohesive coating composition (16) having differential adhesion properties is applied to window glass (12) without regard to covering adjacent trim material (14) which is to be subsequently painted. The DAC (differential adhesion composition) coating (16) is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective adhesion to glass-like surfaces, so that the coating composition (16) may be easily scraped, peeled, or otherwise lifted from the glass (12), together with any paint overlay thereon, after the painting operation of the window frame (14) is completed. When subjected to sheer forces of pulling and scraping, the cohesive properties of DAC coating (16) when considered in combination with a relatively low adhesion to glass, allows the coating (16) to be removed in long continuous strips rather than fracturing into small pieces. Indicia can also be applied to the DAC coating (16) once DAC coating (16) is applied to the glass (12) as a protective coating. Also, the DAC coating (16) can be used directly as a paint so that any paint (18) inadvertently applied to glass (12) or glass-like surfaces during a painting operation can be subsequently lifted off the glass (12).
