Newly installed film needs a settling period before you clean or lower the windows, and your installer will tell you how long to wait for the film and conditions on your car. After that, clean the glass with a soft cloth and a mild, ammonia-free cleaner, and avoid abrasive pads or scrapers on the filmed surface. Any haze or small pockets of moisture in the first days are normal and usually clear as the film cures. For more detail, see our care guide here.
Ask a local tinter whether they carry Kepler film or can get it. For more information, see quick quote.
