Why is the car film initially applied on the outside?

The reason for initially applying the car film on the outside is to more conveniently measure the size of the glass and cut the film according to the dimensions. The functions of the car film include: 1. Blocking heat generated by infrared rays; 2. Filtering ultraviolet rays to prevent skin damage; 3. Safety and explosion-proof, as the base layer of the film is polyester film, which has tear-resistant and penetration-resistant functions; 4. Maintaining privacy and safety; 5. Reducing air conditioning load; 6. Minimizing accidents caused by glare factors. The installation method of the car film is: 1. Adding interior protection to the vehicle; 2. Cutting the car sun film according to the size of the window; 3. Wiping and cleaning the front and rear windshield glass; 4. Using a heat gun to shape the film; 5. Fine-cutting the film after the heat shaping is completed.
I always wondered why the technician worked on the outside first when applying car window film. It's actually for easier cutting and shaping. The exterior surface of the window is flat and free of obstructions, making it simpler to use a knife to create precise shapes that match the glass contours. This prevents messing around inside, so water and debris stay outside and don't drip onto the car's interior or electrical components. After that, the inside of the window is cleaned before the film is officially applied, resulting in a smoother finish with no bubbles. Experience tells me that paying attention to such small details can save a lot of hassle, making the film more durable and heat-resistant, especially when driving in summer to block UV rays more comfortably.
