How many years can we use all kinds of invisible car clothing materials? Many car owners are very concerned about how long the invisible car suit can be used before it is installed. In fact, as a layer of polyurethane film, its service life is not only related to the material, but also related to the usual external environment and use environment. If we exclude the external environment and human factors, just from the material, how long can it be used?

先说TPU材质，实际上这种材质的使用年限就是5年，因为有涂层技术的防护，加上要求定期的保养，一些也可以做到7-8年，很多市场上喊着质保十年，其实就是一个概率的问题，很少有车可以开到8年以上。

Let's start with the TPU material. In fact, the service life of this material is five years. Because of the protection of coating technology and the requirement of regular maintenance, some brands can achieve 7-8 years. Many brands are calling for a 10-year warranty in the market, which is actually a matter of probability. Few cars can drive for more than 8 years.

再说说PVC材质，这种材质在1年半左右，针对低端车型，平时定期的养护，可以使用到2年半时间，一般PVC都没有质保

Besides, the PVC material is about one and a half years old. For low-end models, regular maintenance can last up to two and a half years. Generally, PVC has no warranty

说说PVC的升级材质，PU和TPH，这种升级的材质本质上还是PVC，只是把材质做软并且附上涂层，涂层对材质有一定的保护作用，所以这种材质一般可以使用2年半，定期保养可以做到3年半，所以对于这种材质的质保都是3年。

Talk about the upgraded material of PVC, PU and TPH. The upgraded material is PVC in essence. It's just to make the material soft and attach a coating. The coating has a certain protective effect on the material, so this material can be used for 2.5 years, and regular maintenance can be done for 3.5 years, so the warranty of the brand for this material is 3 years.

以上是我们所说的理想情况，隐形车衣平时风吹日晒，如果是PVC材质，便宜，其实养不养护无所谓，不过PU，TPH，TPU等材质不菲，定期的保养还是很有必要，材质动辄过万，保养可以延长隐形车衣使用寿命，其实也是一种省钱方式，但是保养时大家注意不要使用清洗剂和增亮剂，建议使用三合一技术的隐形车衣保养液，可以清洁，密封，增亮，尤其密封层才是隐形车衣需要的.

The above is the ideal situation. The invisible car clothes are usually windy and sunny. If they are made of PVC, the price is cheap. In fact, it doesn't matter whether they are maintained or not. However, PU, TPH, TPU and other materials are expensive. Regular maintenance is still necessary. The materials are often more than 10000. Maintenance can prolong the service life of the invisible car clothes. In fact, it is a way to save money, However, we should pay attention not to use cleaning agent and brightener during maintenance. It is recommended to use three in one technology of invisible car clothing maintenance fluid, which can clean, seal and brighten, especially the sealing layer is needed for invisible car clothing
