Can the window film provided by 4S stores be used?

The provided film can be used and comes with a warranty. It is recommended to choose a light-colored film to avoid obstructing visibility, especially during nighttime and rainy weather. More information about car window films is as follows: 1. Overview: Car window film (Auto-tint-film) is a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also known as solar film or heat-insulating film. 2. Functions: It primarily blocks ultraviolet rays, reduces heat, prevents injuries from shattered glass, and reduces glare. Additionally, due to the one-way transparency feature of solar films, it helps in protecting personal privacy.
I often get asked by friends about the quality of the window films provided by 4S stores. As a car owner with several years of experience, here’s my summary. The free films are usually basic models made from ordinary materials, such as cheap PET plastic. Their sun protection and heat insulation are decent at first, and you won’t notice any issues for the first few months. However, over time, they tend to bubble, fade, or develop odors due to subpar quality. Their heat resistance and light transmittance fall short of professional-grade films, like high-end metal or ceramic films, which offer better protection for your car interior. If you’re on a tight budget and don’t want to spend extra, the free films can suffice, but it’s advisable to regularly check their condition, especially in high-temperature areas during summer—replace them immediately if they crack. One advantage is the installation; 4S stores have professional technicians who can apply the films without bubbles or dust. Still, consider safety and practicality: films that are too dark may impair nighttime visibility, while overly light ones offer poor sun protection. Overall, the free films are hassle-free but not very durable. My personal experience is that I replaced mine with a better option after two years.
