Should Car Film Be Applied on the Outside or Inside?

[VonMackenzie]

Car film is applied on the inside. The functions of the film are: 1. It can provide heat insulation in summer, saving air conditioning energy; 2. It can reduce energy loss in winter, maintaining the interior temperature; 3. It blocks ultraviolet rays, preventing direct exposure to the interior decor, thereby extending its lifespan and quality; 4. It reduces glare, ensuring safe and comfortable driving. Precautions after applying the film include: 1. Avoid rolling down the windows within three days; 2. Do not clean the heat-insulating film or turn on the defogging heating wires within one week; 3. Avoid using nails or sharp objects to lift the edges of the film to prevent dirt from entering; 4. Do not attach suction cup items to the car film for one to two weeks; 5. If bubbles, displacement, or blurred vision occur on the film surface, seek professional assistance promptly to avoid affecting driving safety.
