How to remove the film on car lights after a long time?

[LeMackenzie]

The method to remove the film on car lights after a long time is: 1. First, you can use your fingernail or a hard card like a bank card to lift one corner of the film. If that doesn't work, you may need to use a wallpaper knife. 2. Then, you can slowly peel off the film. If you want to speed up the process, you can use a heat gun to assist in removing the film, as heating can significantly reduce the adhesive's stickiness. 3. After the film is removed, there might be some residual adhesive left on the surface. At this point, you can use alcohol, tar remover, or hot glue to remove it, followed by rinsing with tap water.
