Is it necessary to apply film on the front windshield of a sedan?

Applying film on the front windshield of a sedan is generally unnecessary unless the windshield has sustained certain damages or cracks, in which case applying film may indeed be necessary. If the windshield cracks, the car window film can act as an adhesive, holding the shattered glass together and reducing the severity of injuries to the driver. However, under normal circumstances, a windshield would not be driven with existing damages. Potential drawbacks of applying film include: it may obstruct the driver's vision, cause reflections on the car body that affect the visibility of vehicles behind, and increase the likelihood of rear-end collisions. If a metallic film is applied, it may also interfere with ETC and GPS signals and cause issues like high reflectivity.
Regarding windshield tinting, after driving for so many years, I believe safety should be the top priority. While car window films can provide sun protection, heat reduction, and aesthetic appeal, overly dark tints can cause blurred vision at night, significantly increasing accident risks—especially on curves or during rainy conditions. Many local regulations strictly prohibit dark windshield tints, and police enforce these rules rigorously. I recommend only applying light-colored, high-transparency heat-rejection films from reputable brands like 3M or LLumar. These can block UV rays to protect interior surfaces but must guarantee over 70% light transmittance to ensure driving safety. Additionally, always check for glare issues post-installation to avoid reflective interference. Regular maintenance is also crucial to prevent bubbles or peeling that could obstruct visibility.
Driving in summer is really tough, with the sun directly baking you inside the car. Window tinting truly helps. I drove a long distance from Hainan to Shanghai with light-colored heat-insulating film applied, and the temperature inside the car dropped significantly. It also saves electricity when using the air conditioning, and my skin is less prone to sunburn. For the windshield, choose a UV-blocking material that doesn’t affect daytime visibility while improving privacy. The key is to have it installed by a professional shop—don’t skimp on cost and opt for low-quality film that may bubble or peel. In hot weather, tinting can reduce interior oxidation and extend the glass’s lifespan. However, remember to clean both the inside and outside of the glass regularly, as dust buildup can affect transparency.
