With the improvement of people's living standards, our car life has gradually developed from simple car to car maintenance. Facing a precise instrument, the maintenance of its various parts can not be ignored. The impression of a car to others must be its appearance, so almost all car owners pay more attention to the maintenance of the paint. From every car wash to waxing, coating and crystal plating, car owners want to make their car look bright.

汽车美容市场的新产品可谓层出不穷，隐形车衣（又称漆面透明保护膜）的问世成为许多豪华车主的爱。相比打蜡、镀膜、镀晶其对漆面的保护在持久性与后续维护上都有显著提升。

New products emerge one after another in the car beauty market. The appearance of invisible car clothes (also known as transparent protective film on paint) has become the love of many luxury car owners. Compared with waxing, coating and crystal plating, the durability and subsequent maintenance of the coating are significantly improved.

同时隐形车衣引以为傲的划痕修复功能能够极 大节约车主的养车成本，节省保费。这也成为商家着重宣传的一大卖点。但事实真是如此吗？在揭晓答案之前我们有必要了解一下隐形车衣的种类。

At the same time, invisible car clothing proud of the scratch repair function can greatly save the cost of car owners, save insurance. This has also become a major selling point for businesses to focus on publicity. But is that really the case? Before we know the answer, we need to know the types of invisibility car suits.

隐形车衣的原理就是在整车漆面上包裹上一层“保鲜膜”，以此防止大气环境中的腐蚀物以及可能对漆面造成划伤的接触物对漆面造成损伤，所以隐形车衣的好坏全在这层膜的材质上。

The principle of the invisible car coat is to wrap a layer of "preservative film" on the paint surface of the whole car, so as to prevent the corrosive substances in the atmospheric environment and the contact substances that may scratch the paint surface from causing damage to the paint surface. Therefore, the quality of the invisible car coat depends on the material of the film.

随着科技的发展，隐形车衣的材质从PU逐渐演变为PVC材质，而近些年TPU与TPU+涂层材质的出现，让车衣实现了自动修复功能。

With the development of science and technology, the material of invisible car clothing has gradually evolved from Pu to PVC. In recent years, the appearance of TPU and TPU + coating materials has made the car clothing realize the automatic repair function.

由于其柔软的拉伸性，让车衣在被石子、树枝等造成轻微划伤时，能够迅速恢复原状。这也就实现了所谓的自动修复。

Because of its soft stretch, the car clothes can quickly return to their original state when they are slightly scratched by stones and branches. This is what we call automatic repair.

这需要特别注意的是，车衣自动修复的伤痕是有限定的，其实车衣能够实现自动修复全依托于车衣表面的两层涂层——0.5mil的聚氨酯透明膜层与6mil的聚氨酯膜。前者主要负责防污，而后者在前者的帮助下，凭借自身柔韧的特性来实现修复。而如果你的伤痕深度大于涂层厚度，那车漆还是会受损。

What needs special attention is that there is a limit to the automatic repair of the scars on the car clothing. In fact, the automatic repair of the car clothing depends on two layers of coating on the car clothing surface - 0.5mil polyurethane transparent film and 6mil polyurethane film. The former is mainly responsible for antifouling, while the latter, with the help of the former, realizes repair by virtue of its flexibility. And if you have a scar deeper than the coating, the paint will still be damaged.

所以回到我们开篇的那个问题，真能节约养车成本与保费？其实这不过是商家噱头。

So back to our opening question, can we really save the cost and premium of car maintenance? In fact, this is just a business gimmick.

势必不会因为这点小伤通过保险修车。但如果从镀晶、镀膜此类美容项目的与周期来看，隐形车衣还是很划算的。

I'm sure I won't get through the insurance to repair the car because of this minor injury. But if we look at the price and cycle of beauty items such as crystal plating and film plating, the invisible car suit is still very cost-effective.

对于车衣的选购其实门道还是挺多的，车衣本身的材质、施工手法都会影响车衣能否尽忠职守。

In fact, there are many ways to choose the car clothes. The material and construction methods of the car clothes will affect whether the car clothes can fulfill their duties.

所以在寻找卖车衣的商家时一定要信奉一分价钱一分货，切勿贪图小便宜，尽量选择各大车衣厂商的直营店。同时车衣本身也分现场剪裁与预先按原车尺寸剪裁两种，二者之间的关系就好像是到买现货的西装还是请人手工定做一样，贴合度肯定有所区别，当然前提条件是施工人员的手艺要过关。

Therefore, when looking for car clothing merchants, we must believe in one price one goods, do not covet small and cheap, try to choose the direct stores of major car clothing manufacturers. At the same time, the car clothing itself is divided into on-site cutting and pre cutting according to the size of the original car. The relationship between the two is like buying a suit in stock at the mall or having it made to order by hand. There must be a difference in the fit degree. Of course, the prerequisite is that the construction personnel must pass the standard.
