Paint protective film propaganda slogan

Not necessarily. Nowadays, many brands promote the warranty 10 years, but in fact, they don't do much. Some car paint protective films have a service life of only 2 to 3 years, and they are also advertised as 10 year warranty. In fact, the service life of some imported big-name paint protective films can really be 10 years. As you said, Shadow Lion has a five-year warranty, which should actually be considered a conservative estimate. Generally, vehicles are basically eliminated in three to five years, and no one will really drive 10 years. Therefore, the quality of the film itself is related to the quality of the warranty, and can not be judged only by the manufacturer's propaganda.
