Abstract：With the continuous deepening of global economic development， the number of motor vehicles has also been increasing. Since the reform and opening up， Chinas automobile industry has developed very fast. In 2018， Chinas motor vehicle ownership was almost 327 million. The volume is very large， followed by the follow-up of automobile after-sales service， especially with the increase in traffic accident rates in recent years， the automobile maintenance business volume has continued to increase， of which automobile body sheet metal repair is an important component of the maintenance business volume. As many car owners now pay more and more attention to various aspects of the cars performance， especially the safety of the car body， the use of traditional sheet metal repair methods is less and less favored by car owners， which promotes the continuous innovation of new car body sheet metal repair methods. This article mainly describes the non-marking repair method in the new method of car body repair. By comparing the advantages and disadvantages of the non-marking repair method and the traditional repair method， the importance of the non-marking repair in the car after-sales maintenance is explained.

當汽车发生碰撞的时候，汽车车身基本上都会发生变形损伤，而这种损伤的程度有轻有重。有的情况可能是车身零部件破碎，有的情况可能是变形且油漆受到破坏，但有些只是变形而已，并没有伤到油漆，对于破碎和伤到油漆的这种损伤，我们修复只能采取更换和重新喷油漆，而对于车身油漆没有受到损伤的情形，我们在进行维修时就可以采用新型的维修方法—车身无痕修复法。
