What are the techniques for applying car window film?

[Harris]

Here are the steps for applying car window film: 1. Measure the window dimensions and cut the film accordingly. The size must be appropriate. If you're not confident in measuring accurately, the film can be slightly larger, but never smaller. 2. Clean the car window glass thoroughly. Spray water on the glass, first use a hard squeegee to remove obvious dirt, then use a soft squeegee to remove water marks. Repeat this process three to four times until all water is completely removed. Finally, spray water on the completely cleaned window, close the window, and leave only the person applying the film inside the car. 3. Apply the film. Peel off the film, evenly spray water on the adhesive side, and set aside the removed plastic backing. Leave a 5-10mm gap at the top of the glass, then attach the sprayed film to the car window to secure it. If the film is slightly oversized, carefully trim the excess without scratching the glass, then use a soft squeegee to remove all water between the glass and the film.
