The shop for the windows tints says that they have two types of films. The one that has metallic composites on it and the other one that is made of ceramic. He said that the ceramic type, is the one you should choose if you have radars or any other type of electronic device in your vehicle. He said, because the metallic type tends to mess and distort the signals. Is that a true statement?, because the price for the ceramic is like 3 times the price of the metallic film. Any help or ideas are very welcome and appreciated.
