The service life of a color change film is closely tied to the quality of the film you choose. With an average-grade film, you can normally expect 2 to 3 years. Choose a better film and take care of it properly, though, and the lifespan can stretch to around 7 or 8 years.
A color change film protects the bodywork. It shields the paint from corrosion and oxidation, adds a layer of protection and extends the life of the original finish. Registration matters too: a color change film has to be registered within ten days, so that the vehicle can be identified easily if it is involved in an accident.
Installation technique and film quality both have a major impact on how long the film lasts. Poor-quality film or sloppy installation can lead to bubbles or peeling, which shortens the service life considerably. So if you decide to wrap your car, go to a professional 4S dealership and choose a film of decent quality. That is the best way to protect your car.
2 years is not a hard limit. Depending on film quality, maintenance and installation skill, a color change film can last up to about 8 years. Weigh all of these factors before you commit, so you end up with the film that suits your car best and keeps it looking good for years.
