[DiAyla]

If the film provided by the 4S store is from a reputable brand with good quality, it can be applied. However, if it is a low-quality film, it is recommended not to use it. Regarding whether the items given by 4S stores when picking up the car can be used, car owners need to be vigilant and carefully assess the quality of these films. Car film refers to the film applied to the surface of car glass, and its functions include: 1. Blocking solar heat and blinding glare; 2. Reducing the load on the car's air conditioning system, improving fuel efficiency, and enhancing driving comfort; 3. Blocking UV rays to protect the skin of passengers from sunburn and slow down the fading, aging, and cracking of interior materials; 4. Enhancing driving safety by keeping glass fragments in place in case of breakage, preventing injuries; 5. Creating a private space to prevent others from peering in.
