Is Car Washing Necessary Before Applying Car Film?

[DeDominic]

Washing the car is necessary before applying film. Whether you're changing the color with a film or applying a "paint protection film," ensuring the car is clean and tidy will yield the best results. If you apply the film directly without washing the car, the large amount of fine dust particles on the car's surface can compromise both the appearance and effectiveness of the entire film. Car films primarily serve as a layer of heat insulation. Changing the car's color with film is cost-effective and doesn't alter the original paint. Nowadays, with high UV levels in summer, especially in southern regions, drivers are exposed to significant sun exposure. Therefore, most car owners still opt for car films. However, since there is no standard for post-application quality, the skill of the installer is the only way to gauge the quality of the application. The currently advocated dust-free film application isn't entirely dust-free. During the process, both the glass and car body are in a damp state, making them prone to attracting dust. When inspecting the film, as long as the dust isn't overly noticeable and doesn't obstruct the driver's view, a minimal amount of dust is acceptable.
