Is the window film applied to the outside or inside of the glass?

Car window film is applied to the inside of the glass to avoid damage from external environmental factors. Below is a relevant introduction: Function: An important function of car window film is explosion-proof. When the glass spontaneously breaks or shatters due to external impact, the film can hold the glass fragments together, preventing secondary injuries to passengers and enhancing safety. If applied to the outside of the glass, the film and wipers may scrape against each other during use, and rain or windblown sand can continuously erode the film, affecting its effectiveness. 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 a 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.
I'm the kind of car owner who enjoys DIY projects, and I've been through the car window tinting process a few times. At first, I made the mistake of applying the film on the outside, which quickly got ruined by wind and rain. Later, I learned that window tint film is supposed to be applied on the inside, not the outside, for three main reasons: First, the outside has wipers that would rub and damage the film. Second, direct exposure to sunlight, UV rays, and high temperatures would cause the film to age and bubble quickly. Third, any rainwater or debris would compromise the film's clarity. My advice if you're tinting: first check the cleanliness of your windows to ensure they're dust-free before applying. Choose a good quality heat-resistant film to block UV rays, protect your interior, and enhance privacy. Remember, correctly applied on the inside, it won't affect visibility, but if you're not confident in your DIY skills, it's better to go to a professional shop to save money and time in the long run.
