[AliceMarie]

Precautions after applying window film in winter include: 1. Avoid rolling windows up and down for 3 days; 2. Do not clean the heat-insulating film or turn on the defogging heating wires for a week; 3. Do not use fingernails or sharp objects to pry the edges of the film to prevent dirt from entering; 4. Avoid attaching suction cup items to the film for 1 to 2 weeks; 5. If bubbles, displacement, or blurred vision occur on the film surface, seek professional assistance immediately to avoid affecting driving safety. The functions of window film are: 1. Heat insulation in summer, saving air conditioning energy; 2. Reducing energy loss in winter and maintaining the interior temperature; 3. Blocking ultraviolet rays, preventing direct exposure to interior decorations, thus extending their lifespan and quality; 4. Reducing glare to ensure safe and comfortable driving.
