Here is relevant information about car window film application: 1. Time: After completing the car window film application, it takes about 3 days in summer and 7 days in winter. 2. Requirements: Do not roll the windows up and down arbitrarily during the required time. 3. Note: For cars with newly applied window film, the glass is usually tight, and the edges of the car film can easily curl and lift during the opening and closing of the windows, causing damage to the car film. Additional information is as follows: 1. Enhanced anti-shatter performance: When glass with film applied is accidentally impacted and shattered, the tightly bonded film will slow down the impact speed of glass fragments, providing an anti-shatter effect. The film also has anti-scratch properties. 2. Anti-glare: It can reduce the impact of strong light and glare on the driver's vision, enhancing driving safety. The degree of filtering depends on the film's light transmittance. Films with too high or too low light transmittance are not recommended. The selection criterion should be based on comfortable eye perception and unobstructed vision. 3. Heat insulation: The film has the ability to reflect and absorb visible light, effectively blocking a certain amount of heat and preventing excessive temperature inside the car. 4. Protection against harmful UV rays: UV radiation has a sterilizing effect but can also harm human skin. Without window film, prolonged sitting in the car can easily lead to UV damage and skin diseases. Sun protection films can effectively block UV rays and protect the skin from harm.
I remember getting dark tint film applied to my new car last summer, and the technician immediately warned me not to roll down the windows right away. Typically, it's recommended to wait 48 to 72 hours to allow the adhesive to fully cure. If you roll down the windows too soon, especially in rainy or dusty conditions, moisture can easily seep in, causing bubbles or peeling at the edges, which affects both appearance and UV protection. I once couldn't resist and rolled down the window the next day for some fresh air, only to end up with small bubbles on the right side, costing me extra for a redo. Generally, it's best to park the car in an indoor garage for the first couple of days after tinting to avoid direct sunlight accelerating film aging. Waiting patiently before normal use not only extends the film's lifespan but also saves on repair costs—definitely worth it.
