Is it necessary to apply film on the vehicle's front windshield?

[DeJace]

It is necessary to apply film on the front windshield of a car. The functions of the film are: 1. Blocking ultraviolet rays; 2. Reducing heat transmission; 3. Preventing injuries caused by flying glass fragments; 4. Reducing glare; 5. Protecting personal privacy; 6. Lowering the interior temperature through physical reflection, reducing the use of car air conditioning, and thus decreasing fuel consumption. Precautions after applying windshield film: 1. Wipe the glass within a week to prevent the film from shifting if it hasn't fully adhered; 2. Avoid using sharp or rough tools to scratch the film; 3. Avoid using highly corrosive chemical solvents to clean the film surface. For scratches on the windshield film, the solution is to polish and repair them with glass polishing paste.
