Is car film applied on the inside or outside of the car?
2 Answers
Car film is applied on the inside of the car because it won't be exposed to wind and rain, thus aging more slowly and extending its service life. Precautions for car film application: Before applying the film, protect the interior facilities by covering the seats and dashboard with plastic covers. During application, avoid using lubricants that may cause the film to fade, and do not apply the film under direct sunlight, as this can lead to wrinkling and bubbling, significantly affecting the appearance of your car. The cleaning of the glass is the foundation for a good application. Generally, there are three steps to cleaning the glass: inspecting for damage, removing adhesive particles and sand, and dusting and cleaning the glass (since water is used for dusting and lubrication, be careful to prevent water from leaking into the car's audio and electronic control systems, and ensure the glass is cleaned three times). When cleaning the rear windshield, take care not to damage the heating wires. Functions of car film: The functions of car film include blocking ultraviolet rays, reducing heat, and preventing injuries caused by sudden glass shattering. It also protects personal privacy due to the one-way visibility of the solar film. Additionally, it can reduce air conditioning energy consumption, enhance aesthetics, and, to some extent, help save fuel consumption.
As a long-time car enthusiast, I know that car window film is applied to the inside of the windows. This is because installing the film on the interior protects it from external environmental damage, such as wiper blades and sand abrasion, which can ruin the film's surface. If applied externally, it would quickly bubble or peel off. After applying UV-blocking and heat-insulating film to my own car, driving in summer became much more comfortable—the interior doesn't get too hot under direct sunlight, and it also protects the skin. During installation, professionals use specialized tools to clean the glass, spray water for lubrication, and carefully apply the film to ensure no bubbles form. I recommend choosing reputable brands with compliant light transmittance—don’t go for cheap options, as they tend to yellow and degrade. In short, proper placement ensures durability and lower maintenance costs.
