ABSTRACT OF THE INVENTION Apparatus and methods for spray coating selected areas of a circuit board with an insulative coating material without coating regions of the circuit board to be left uncoated. A liquid spray device emits the coating material and an air assist attachment connected to the liquid spray device directs jets of air into impinging relation with the coating material emitted therefrom to transform the coating material into an atomized, shaped spray pattern for coating the selected areas. The air assist attachment can be disabled so that the spray device transforms the coating material into a non-atomized, shaped spray pattern for coating selected areas without coating regions of the circuit board to be left uncoated.
