Should the side window film of a car be applied on the inside or outside?

Automotive side window film should be applied on the inside. Here are the relevant details: 1. Applying the side window film on the interior side protects it from exposure to wind and rain, enhancing its anti-aging properties and thereby extending the film's lifespan. Additionally, the film is less susceptible to external disturbances during use, reducing the likelihood of scratches or damage, and preventing the edges from peeling. 2. The advantages of automotive window film include: (1) Heat and sun protection: The film effectively blocks a significant amount of heat generated by infrared rays. (2) UV protection. (3) Safety and explosion resistance, creating a private space. (4) Reducing air conditioning energy consumption, improving aesthetics, and preventing glare.
I've been driving for over a decade and have applied window film many times, always choosing to install it on the inside of the glass. At first, I was curious why it wasn't applied on the outside, but later I found that films on the exterior quickly develop scratches and bubbles, especially during car washes or rainy days, making them prone to damage. Applying the film on the inside ensures it lasts longer and stays durable, avoiding contamination from dust and bugs. During installation, technicians clean the interior glass surface indoors, spray water, and then smoothly apply the film with a squeegee to ensure no bubbles. This also effectively blocks heat and UV rays, keeping the car cooler in summer and protecting seats from cracking. It enhances privacy as well, making it harder for outsiders to see inside. Now, I do this for every car I own, and the overall results are very satisfying.
