2. How to repair the sunken aluminum door?
All-aluminum doors can be repaired, but the damage should not be too great. For example, aluminum itself is not hard enough and may crack, so it can only be replaced and cannot be repaired. Generally, the best way to repair is to go to a 4s shop, because the technology of the 4s shop is better, and the repairman outside the repair shop may not be able to repair it well, or the maintenance effect is not good, and it is easy to paint off or repair it from the surface.
Generally, only a slight collision can repair it. Aluminum can only be repaired by slapping the wound as slowly as possible, or you can apply vaseline to the joint with the toilet plunger and pull it out at the pressed position. Can only be used on door panels.
The advantage of aluminum for automobile is its good ductility, and it can be synthesized with many other materials, including high-quality materials such as aluminum alloy. The most important thing is to reduce the weight of the car and improve the handling performance.
