Can You Apply Another Layer of Film Over the Existing Car Film?

[LaLouis]

It is generally not recommended to apply another layer of film over the existing car film. Here are the relevant details: Reasons: If another layer is applied, the treatment effect of the film may be compromised. Additionally, applying new film directly over the old one without removing it makes it difficult to clean the dust on the old film thoroughly, which can lead to impurities. The moisture trapped between the layers may not evaporate properly, causing bubbles to form. Applying double layers of film can also impair the driver's visibility, reducing safety. Film lifespan: If the film is of good quality, it can typically last 5 to 10 years after application. However, if the film is of poor quality, it may only last 1 to 2 years. Nevertheless, it is advisable for car owners to use high-quality film, as although it may be more expensive, it offers a longer lifespan and better protection.
