How to remove trapped hairs from under film.
Method 1: Assuming you’ve caught it before drying, use a marker to circle the hair so you don’t lose track of it. Start peeling from the nearest corner and thoroughly spray the window with your solution. Use your finger to remove hair, and then spray the area again. Reapply the film and then use your card to force out the water. Look at the circle that you drew and make sure the hair is gone.
