  • Patent number: 7736692
    Abstract: A process for applying an adhesion primer to a window. The process includes the steps of directing light (11) onto the window (10) to illuminate a portion (13) of the window and then applying an adhesion primer along the illuminated portion of the window. If the adhesion primer contains a component that evaporates, then the process can further include the step of forming an infrared image (19) of the window as the component evaporates to indicate the area of application (20) of the adhesion primer. If the adhesion primer contains a component that fluoresces when illuminated by ultraviolet light, then the process can further include the step of illuminating the window with ultraviolet light (22) to indicate the area of application (23) of the adhesion primer.
