What is the reason for the peeling of a layer of film on car headlights?

[VonJulianna]

It is likely because after picking up the car, the original factory headlight film was not removed. Although it sticks to the headlight cover, over time, it may start to peel. Removing car headlight film: You can use your fingernail or a hard card like a bank card to lift one corner of the headlight film. If that doesn't work, a wallpaper knife may be needed. The film can be slowly peeled off. If you want to speed up the process, you can use a heat gun to warm the film, as heating reduces the adhesive's stickiness. Car headlight color-changing film: Protection against gravel impact during high-speed driving: Small scratches from gravel usually don't heal naturally, and there are often many such scratches. Using a protective film can effectively prevent damage and keep the headlights looking new. Protection against minor scratches in daily life: It can prevent minor abrasions, water stains, and scratches from washing the car, etc. Personalized decorative effect: With multiple color options, it can decorate your car and add a finishing touch. Unlike spray paint, car headlight color-changing film can be peeled off anytime, leaving the headlights as good as new.
