The dent in the door has been repaired. Do you want to tear it down? How to repair the depression without tearing down the door?

If the car is scratched, all the doors are recessed. In the case of going to the 4S shop to repair the car, the 4S shop proposed to replace all the doors. Many people are struggling whether to replace all the doors or make sheet metal, because he is struggling with the original doors, and the replaced doors are undoubtedly not as good as the original ones. Although such things can be done by sheet metal, sheet metal is manual, and the door is sunken, so it needs to be sucked out with articles. Under normal circumstances, the sheet metal master can replace it, but he is unwilling to do sheet metal, and the surface is uneven after finishing, so he should level it with putty and then paint it. After a long time, it may rust inside.

Therefore, I will tell you this phenomenon that many good friends may encounter. We can't generalize the problem of replacing or repairing sunken doors. First of all, analyze whether the car was hit seriously from a realistic point of view. If the door is dented only once, it does not involve the deformation, damage and bending of the metal structure, and it can be pulled out as long as it is sucked hard. Therefore, it is suggested that you make sheet metal directly and scrape it with molecular dark gray paint, so that you can keep the original car door.

If the door is badly hit, the door is cracked, the metal sheet metal is bent in the corner area, or some structural columns and parts are damaged, if this happens, Brother Miao suggests that it is best to replace them all, and never do any sheet metal maintenance again, and never entangle the problem that the original parts are not original parts. If you make a sheet metal, the inner anti-corrosion layer and corrosion resistance have long been destroyed, and the compressive strength of the metal has long changed. After the door is used for a period of time, because there will be water vapor inside the door, the door will corrode from the internal structure after long-term use. Even if a thick putty is scraped outside, it will not resist corrosion for a long time. Once the metal material inside rusts through putty, it will fall off one by one, or the paint will gradually leak out after a long time.

From a realistic point of view, it is necessary to analyze whether the car was hit seriously. If the door is dented only once, it does not involve the deformation, damage and bending of the metal structure, and it can be pulled out as long as it is sucked hard. Therefore, it is suggested that you make sheet metal directly and scrape it with molecular dark gray paint, so that you can keep the original car door. Now the cost of simple sheet metal spraying is not high. If the cost of changing the car door will be high, insurance will be taken immediately, which may also lead to an increase in the premium in the second year. The second reason is appreciation, which will endanger secondary sales. The same car without changing the door is more popular than changing the door. After all, it is the main room, and at this stage, many repair shops use auxiliary doors, and the quality is different. Even the original door is expensive.
