500ml of window film polish in a spray bottle. Film Polish is a cheap and simple way to ensure your window films stay in prime condition. Window film polish offers a protective shine to the window film and creates a dirt-repellent layer. Use after installing window film to buildings & car window tints. Simply spray the installed window film with the polish. Use an ultraclean cloth and keep polishing until the surface looks clean, shiny and smooth. You may need to use several cloths. Make sure they are clean & dry. The drier the cloth, the better the polishing result.
