Why is the Car Film Applied on the Outside
4 Answers
Car film should be applied on the inside of the car. Actually, the film is not applied on the outside; it is only placed there temporarily. It is more convenient to cut the film on the outside of the glass because the interior space is limited, making it difficult for the technician to maneuver and operate. Cutting the film on the outside ensures greater precision and convenience. The steps are as follows: 1. When going to get the car film applied, first check the environment where the film will be applied, as dirt or debris might get trapped under the film. Therefore, it is best to choose an enclosed environment. 2. When applying the film, make sure it is genuine by checking the anti-counterfeit label. 3. The most challenging parts to apply the film are the front and rear windshields due to their curvature. To avoid bubbles, it is recommended to ask the installer to divide the film into smaller sections. 4. After application, carefully inspect for any defects. Sit inside the car and check if the edges are lifting or if they obstruct the driver’s view. 5. Request a warranty card. The reasons for not applying the film directly on the outside of the glass are as follows: 1. It gets dirty easily and is inconvenient to clean. 2. It is prone to damage, not just from human factors but also from external elements. 3. It ages faster due to the harsh and variable outdoor conditions, which accelerate the film’s deterioration.
I once had a painful experience with an exterior application—the film started bubbling, scratching, and getting covered in dust in no time. Generally, car window film should be applied on the inside because the exterior faces harsh conditions like wind, sand, and rain while driving. Applying it inside offers excellent UV protection, maintains privacy, and resists aging and bubbling. This design is scientifically chosen, tested thousands of times in factories—applying it outside is just foolish. Now, I maintain my car by cleaning the interior glass every six months, and the film still looks shiny, saving both money and hassle. Don’t make the same mistake I did—get it professionally installed for safety and reliability.
My car was just tinted last year, and the technician insisted it must be applied on the inside. Why? If it's on the outside, rain or snow can seep in, causing the film to bubble or fog up, which messes with visibility. Applying it on the inside avoids this issue—the film adheres tightly and also helps prevent injury from glass shattering in case of breakage. I've picked up a bit of car knowledge myself, and applying it on the outside also reduces the film's functionality, like cutting its heat and UV protection by more than half. Installation is easier too—the interior glass is cleaner and smoother. I’d advise beginners not to try applying it on the outside to avoid bigger headaches down the road.
Applying car film on the outside is unreliable. From a safety perspective, applying film on the inside can prevent explosions, ensuring that shattered glass doesn't scatter. Externally applied film is prone to scratches from small stones or branches and may violate traffic regulations due to inaccurate light transmittance affecting nighttime driving. Applying it on the inside can extend the film's lifespan by more than three times. Don't skimp and apply it carelessly; pay attention to the details.
