Car window tinting is the process of applying a thin film to the windows of a vehicle to reduce the amount of sunlight that enters. This film can help block harmful ultraviolet (UV) rays, which can protect the interior of the car and reduce heat buildup. Tinted windows can also enhance privacy for passengers and belongings inside the vehicle. There are various types of tint films available, including dyed, metalized, and ceramic options. Each type offers different levels of heat rejection, UV protection, and visibility. Window tinting laws vary by state, so it's important for car owners to check local regulations before applying tint to ensure compliance.
