Vinyl Automobile Cling in White. To apply Static clingfilm to a glass window, begin by thoroughly clean your window and carefully cutting the static cling film to the measurements required. Fill a spray bottle with water and two drops of dish detergent, and lightly spray this on the entire window. Peel the backing and carefully line the cling film to the top of the windowpane, pressing firmly to secure it into place. Finally, smooth the film against the window with a squeegee, moving from the middle toward the edges, to smooth out any bubbles.
