16 Abstract A flux coating solution for treating a clean metallic component having a fluid channel defined through at least a portion thereof (2,4) to provide a durable, tack-free, protective flux film (6,8) on a surface of the portion so that the component (2,4) can be fluid-tightly soldered or low temperature brazed to a mating metallic component (2,4) at a later time without cleaning and fluxing the portion of the component at the later time. The solution consisting essentially of rosin and a highly volatile organic solvent, the solution being adapted to rapidly air dry when coated on the surface of the portion to leave a very thin, protective flux film (6,8) on the surface of the component (2,4), the component (2,4) being capable of being stored for long periods of time, handled, assembled, shaped, formed and otherwise worked without removal of the film (6,8) from the surface of the component and without reduction of the fluxing properties of the film (6,8).
