First of all, it is easy to neglect whether there are pockets on the surface of automobile sheet metal by hand, but it is also very important. After leaving the factory, the white body comes to the painting workshop through electrophoresis and other processes. At this time, the surface may have a small irregular bulge. In order to prevent it from affecting the spraying effect, the staff will do careful inspection and remove the defects with special tools. Of course, it may be because some of the judges'carelessness can not be found in time, then you need to touch it by yourself.

It is said that the workers who make Lexus can feel the slight difference in the car body by hand. It is very difficult for us to reach the same level without professional training. But you should not worry too much. After all, a car that meets the factory standard is not easy to have the defects visible to consumers.

Secondly, we also need to observe the clearance and smoothness between the various panels.

Regarding the gap, the standards of each host factory are different, which is related to brand positioning. After all, it is not realistic for you to make the flying speed reach the level of E. The cost is in front of you, and the gap needs to be faced. If you have a pair of plug rulers on hand to measure, it is a more professional approach. However, it is simpler and more commonly used to touch the small thumb along the gap to feel whether it is even or not.

Let me add that some of the seams in the car body will be designed to be larger because of safety considerations. At this time, you don't have to worry about whether the quality of sheet metal is not up to standard. Some locations, such as engine hatch and fender, if the little thumb can be stuffed in, it will definitely indicate that there is a problem in the assembly level.

As for the flatness, the simple judgment method is also to feel the flatness by hand, at the junction of the front cover and the fender, and feel the flatness by hand. The left and right sides should be the same, and the left and right sides should not be asymmetrical. In addition to the front cover and fender mentioned earlier, you should also pay attention to small details such as tank cover, which often expose the carelessness of manufacturers.
