Is the car window film applied on the inside or outside?

[DeRosalie]

Automotive window film is applied on the inside of the glass. Factors to consider: This is to protect the film from damage caused by external environmental factors. An important function of automotive window film is explosion-proofing. In the event of spontaneous glass breakage or impact-induced shattering, the film can hold the glass fragments together, preventing secondary injuries to passengers and enhancing safety. Maintenance after applying car window film: Avoid washing the car for the first three days after application to prevent the film from peeling off due to moisture. Also, try not to use the rear window defroster for the first week, as moisture can negatively affect the defroster lines. After installation, you can clean the film surface with a damp towel, sponge, or soft cloth. Avoid rolling the windows up and down for a few days after application, as the film may shift if not fully adhered. If the film becomes loose during washing, return to a professional installation shop for re-securing to ensure effectiveness and durability.
