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

You can open the windows 5 days after applying car film. Opening the windows prematurely may cause the film to shift and create wrinkles at the edges. Additionally, you should avoid washing the car for 3 to 5 days after applying the film. Car film (Autofilm) refers to a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This layer is also known as solar film or heat-insulating film. The primary functions of car film are to block ultraviolet rays, reduce heat, prevent injuries from shattered glass, reduce glare, and protect personal privacy through the one-way transparency feature of the solar film.
I just got my car windows tinted and specifically consulted the technician. Actually, opening windows before the tint film is completely dry can easily cause shifting or bubbling, especially the front windshield film which is the most fragile. In spring and autumn, it's recommended to wait 3-4 days before rolling windows up/down, while in cold dry winters you should extend this to 5-6 days. Last time I got tints in hot weather, I couldn't resist opening windows the next day - the film edges lifted and I had to redo it, wasting money for nothing. The key is observing moisture evaporation between glass layers; if edges still look foggy or show water ripples, wait longer. Remember to avoid using defogger function in the first few days, as large temperature differences also affect adhesive curing speed.
