How many days after applying the film can you open the windows?

You can open the windows three days after applying the film. The functions of the film are: 1. Blocking ultraviolet rays; 2. Preventing vehicle scratches; 3. Reducing the temperature inside the car; 4. Anti-glare; 5. Maintaining glass clarity. Types of car films: 1. Ordinary film; 2. Explosion-proof film; 3. Sunscreen and heat insulation film. The structure of the film: wear-resistant layer, PET safety base layer, metal heat insulation layer, UV absorption layer. The steps for applying the film are: 1. Install interior protection for the vehicle; 2. Cut the car film according to the window size; 3. Clean the front windshield; 4. Use a heat gun to shape the film; 5. After the film is heated, perform fine trimming on the film.
The tinting technician told me not to touch the car windows for at least 72 hours, which is the same principle as applying a phone screen protector. There's a layer of moisture between the newly applied film and the glass, and opening the windows can cause the edges of the film to curl or shift. I waited until the sixth day to open the windows for my SUV, and in rainy weather, it's better to extend that by another two days. Extra caution is needed for the rear windshield—the tint shop mentioned that opening windows near the heating wires can easily cause bubbles. Actually, the best approach is to use the air conditioning's defogging function instead of opening the windows. Keep some wet wipes in the passenger seat to wipe off sweat and tough it out for a few days. Remember not to let kids randomly press the window buttons—last time, I had to spend an extra 300 bucks for a redo.
