What to do if you don't have a heat gun for motorcycle film application?

You can also apply the film without a hot air gun, you can use a household hair dryer instead.
In fact, the role of the hot air gun in car film application is to bake the film and shape it.
Because the surface of the car body will have a certain curvature after the film is applied, we also need to bake the car film and shape it before applying the film.
