Is it okay not to apply film on the front windshield?

[MatteoRose]

Yes. The front windshield itself has the function of blocking ultraviolet rays, so it is not necessary to apply film. If you do choose to apply film, make sure to use genuine products from well-known brands. Inferior quality films may not meet the required light transmittance standards, which can affect the driver's visibility and lead to safety accidents. Below are some precautions for car window tinting: Preparatory work before applying film: Before applying the film, it is necessary to protect the interior facilities of the car by covering the seats and dashboard with plastic covers. Do not apply the film under direct sunlight, as this can cause the film to wrinkle or bubble, affecting the car's appearance. Preventing the film from falling off: Do not wash the car within three days after applying the film, as washing may cause the film to peel off. After the film is applied, do not roll down the side windows for 24 hours in summer and 48 to 72 hours in winter, as rolling them down may cause the film to shift. If bubbles are found, they should be treated at a professional car beauty and maintenance shop within 24 hours.
