Is it necessary to apply film to the car windshield?

[McRhett]

Applying film to the car windshield is necessary for the following reasons: 1. It provides heat insulation in summer, saving energy for air conditioning; 2. It reduces heat loss in winter, maintaining the interior temperature; 3. It blocks ultraviolet rays, preventing direct exposure to the interior decorations, thus extending their lifespan and quality; 4. It reduces glare, ensuring driving safety and comfort. Precautions after applying the film include: 1. Avoid rolling down the windows within 3 days; 2. Do not use nails or sharp objects to pry the edges of the film to prevent dirt from entering; 3. Avoid attaching suction cup items to the film for 1 to 2 weeks; 4. Address any bubbles, displacement, or blurred vision on the film promptly to avoid affecting driving safety.
