It is necessary to apply film on the inside of the windshield. The functions of the film include: 1. Heat insulation, especially in summer, reducing the rise in temperature inside the car and alleviating the load on the air conditioning; 2. Privacy, after applying the film, it becomes one-way visible, making it difficult to see inside the car from the outside. If a thief attempts to steal, their view will be unclear; 3. In case of an accident, the film helps prevent glass shattering. During an accident, it aids in securing the fragments of broken glass, holding the glass in place to prevent accidental injuries. The purpose of the car film is to prevent broken glass from flying and causing accidents. Precautions for car film application: 1. After applying the film, avoid rolling down the windows for three days and do not wash the car during this period; 2. For vehicles with sunroofs, avoid opening the sunroof while driving, especially at high speeds, within three days.
