What if there is a small hole in the door? Repair and treatment skills of car door pits
If you find a small pit on the door, you should pay attention to it and repair it in time. What about the potholes on the door? Bian Xiao, let me share how to deal with the dent in the car door.

What if the problem is not just a small scratch, but has been knocked out of the pit, or there is already a big scratch? You can't solve it with a touch-up pen at this time. What is needed is sheet metal and paint. Sheet metal is a comprehensive process of cold working sheet metal and repairing the deformed part of automobile metal shell. If the door is knocked out of the pit, it can be repaired with metal sheets.

What are the main working skills of car door pit sheet metal maintenance?

(1) First, the compressed frame is stretched to the state required by the original data by using a special sheet metal platform.

(2) The next step is fighting. By using hammers with different textures, sizes and shapes and cooperating with various molds, the hitting strength and angle of the performer are controlled, and the bent, concave or convex parts are restored to the state required by the original data.

(4) The final work is polishing. Through the cooperation of various polishing materials and instruments, the repaired surface will be polished and leveled to prepare for the painting process.

Through sheet metal work, the potholes caused by the collision of the original doors can be repaired and restored, and the sunken and deformed doors can be restored to their original state without replacing a door.

Repairing the potholes in the door and the potholes on the outside of the car is the best solution. Of course, there is another project after sheet metal, which is painting. Because after the sheet metal work, the paint on the automotive sheet metal will be worn and peeled off due to the operation of tools. Therefore, after the sheet metal work is completed, the sunken automobile door panel should be painted to restore the beauty of the door.

Generally, car owners can't finish the sheet metal work by themselves, and they need to finish it through the garage.
