Should You Wash Your Car Before Applying Window Film?

[DaisyRose]

It is necessary to wash your car before applying window film. If the car body is not clean, bumps may appear after the film is applied, which not only affects the appearance of the car but also makes the raised areas more prone to damage. Car window film involves applying a thin layer of material to the front and rear windshields, side windows, and sunroof of the vehicle. This thin material is also known as solar film or heat-insulating film. The primary functions of solar film include blocking ultraviolet rays, reducing heat transmission, preventing injuries from shattered glass, minimizing glare, and, due to its one-way transparency, protecting personal privacy. Solar film can also reduce damage to interior items and passengers caused by UV exposure. By reflecting sunlight, it helps lower the interior temperature, reducing the need for air conditioning and thereby improving fuel efficiency.
