Can Car Tint Film Be Applied on the Outside?
2 Answers
Car tint film cannot be applied on the outside because it is exposed to wind and sunlight, which can cause it to age quickly and have a very short lifespan. Therefore, it is usually applied on the inside of the glass. Below are the advantages of applying the film on the inside and some post-application precautions: Advantages of applying the film on the inside: It provides some protection against damage from external environmental factors. In the event of glass shattering due to spontaneous breakage or external impact, the film can help hold the glass fragments together, preventing secondary injuries to passengers and enhancing safety. Precautions after applying the film: After applying the tint film, avoid rolling down the windows for three days, do not wash the car for three days, and if the vehicle has a sunroof, avoid opening it while driving, especially at high speeds, during the first three days.
When I was young, I was curious whether car window film could be applied on the outside, so I tried it once, and problems arose quickly. The film is designed to be applied on the inner side of the window. Applying it on the outside exposes it to rain, dust, and car wash brushes, causing it to bubble and peel off rapidly, which also compromises visibility and safety. After applying it, I only drove for two days before it became blurry in the rain, nearly causing an accident. Later, I learned the correct method: choose UV-protective film for the inside—it protects privacy, blocks heat, and extends its lifespan. Regularly cleaning the inner side of the window is key—don’t cut corners like I did, saving small money only to spend more on reapplication. Applying film on the outside isn’t worth the risk; it’s safer to follow professional advice.
