The invisible car suit is just like its name. The naked eye can hardly see the existence of the car suit. The appearance of the car itself will not change after it is pasted. It is just like an invisible guard, protecting the paint of your car all the time. Many car owners don't have much time to find that their clothes are yellowing after they put on the stickers. What's the reason for this?

隐形车衣之所以会变得发黄还是因为氧化造成的，不管是什么材质的车衣，都会面临变黄的情况，只是时间的长短，长的能保持十年左右的时候才会开始发黄，而有的甚一年左右就会变黄了，当然隐形车衣变黄的长短与它的材质和制造技术也脱不了关系。

The reason why the invisibility car clothing turns yellow is due to oxidation. No matter what material it is, it will turn yellow. It's only for a long time. It will only start to turn yellow when it lasts for about ten years, and some even turn yellow after one year. Of course, the length of the yellowing of the invisibility car clothing is closely related to its material and manufacturing technology.

PVC材质的寿命就普遍比TPU材质的要短，PVC这种材质的车衣材料偏硬，不容易拉伸，生产成本比较低廉，和塑料膜无异。一般市场上的都不会高于6000元，能起到的保护作用十分有限，而且后期所付出的代价可能远远高于这6000元。

The service life of PVC material is generally shorter than that of TPU material. The car clothing material of PVC material is hard, not easy to stretch, and the production cost is relatively low, which is the same as plastic film. Generally, the price in the market will not be higher than 6000 yuan, which can play a very limited protective role, and the price paid in the later period may be much higher than 6000 yuan.

就以目前来说在隐形车衣引入国内市场的时间并不是很长，选择的时候还是尽量选择一些大的产品，材质上面也是选择TPU加上纳米涂层的隐形车衣，这种类型的车衣在目前来说抗氧化的能力是强的，就算出现了更好产品之后这种类型的也不会差到哪里去，毕竟抗氧化的能力少能保持在十年左右。

For the moment, it's not a long time since the introduction of stealth car suits into the domestic market. When choosing, we should try our best to choose some products of big brands. The material above is also TPU plus nano coating stealth car suits. At present, this type of car suits has the strongest anti-oxidation ability. Even if there are better products, this type of car suits will not be worse, Bi said Actually, the antioxidant capacity can be maintained for at least ten years.
