Car window tinting can last anywhere from 5 to 10 years, depending on the quality of the tint film, the type of tint applied, and how well it's maintained. High-quality films, such as ceramic tints, tend to last longer, while dyed films may start to fade or peel sooner. Factors like exposure to intense sunlight, temperature fluctuations, and improper cleaning can affect the longevity of your tint. Regular care, such as avoiding harsh cleaning chemicals and giving it time to cure after installation, can help maximize the lifespan of your tint.
