Why is the front windshield film applied on the outside?

[DiRuth]

This is the preliminary work for applying film to the front windshield of motor vehicles. First, the film is temporarily affixed to the outside of the vehicle's windshield to cut it to size. After the trimming is completed, the pre-cut film is then applied to the inside of the windshield for normal use. Here is additional information: Whether vehicle film application requires registration procedures: When applying film to motor vehicles, no registration procedures are required. Applying film to vehicle windows falls within the normal scope of modifications and is not considered illegal alteration. Properly applied window film can effectively enhance vehicle privacy, improve the vehicle's aesthetic appearance, and provide heat insulation and UV protection. Precautions for applying window film: When selecting window film for vehicles, choose films with good transparency to ensure better nighttime driving visibility. Otherwise, it may affect the safety of nighttime driving. After application, strictly adhere to the recommended time before operating the vehicle windows. Opening the windows too soon may cause the film to bubble or peel at the edges.
