Doors dented by collision, repair or replacement?
If the door is sunken, judge whether to repair or replace it according to the situation. If the collision is serious, it is recommended to replace it. If you change it, you must change it to the original factory, otherwise many places are not suitable. 1, repair is easy to rust and the surface putty powder will scrape very thick. In this case, the sheet metal repair is basically scraped with putty. 2, artificial knock uneven, can only use putty leveling. That will be thicker, it will crack easily when it encounters temperature difference, and the door will open and close frequently, and it will crack easily when there is vibration. 3. What is new is that when it rains, the door often gets water, and the whole door will be electrolyzed by the setting machine, which will rot if it can't stand long-term corrosion.
