How to Repair a Deformed Car Door Frame?
2 Answers
If the car door frame is deformed, it can be repaired at an auto repair shop or a sheet metal shop using sheet metal technology. Automotive sheet metal is a repair technique that involves restoring deformed parts of the car's metal shell. For instance, if the car's outer shell is dented, sheet metal work can restore it to its original shape. Afterward, specialized paint is applied to make the repaired metal surface as smooth and shiny as the undamaged areas. The car door is composed of the door frame and the lower door panel, which is welded together from two stamped pieces inside and out, with a reinforcing beam welded inside. As long as the frame is not deformed, it can be repaired without affecting safety or sealing performance.
Last time I dealt with a dented car door frame myself. First assess the damage level - if it's a minor dent, you can use knocking tools to restore the flat surface. Use a hard rubber mallet to gently tap the dent, combined with a heat gun to soften plastic parts. Afterwards, you'll need to repaint to match the color and prevent rust. For severe deformation, you'll have to remove the door to realign the frame structure, but this process carries risks of improper operation causing self-injury, so I recommend beginners only attempt minor repairs in their home garage and leave major issues to professionals. The waterproof seal must be properly restored, otherwise rainwater leakage could damage internal components. Keep some sandpaper and spray paint handy, and always park carefully to minimize collision risks.
