What to do if the lower door sill is scratched and dented?

It is recommended to go to a 4S shop for repair, and if you have insurance, you can also apply for insurance compensation. Here is more information about door dents: 1. Repair category: As long as the paint surface is not falling off or peeling, and the dent is not very deep, it can be repaired with professional tools to restore the body to its original state as much as possible. If the dent is very deep, go to a 4S shop for inspection, sheet metal work, and repainting. 2. Door maintenance: Regularly check and maintain the door seals, and keep the door hinges lubricated to reduce wear and tear and make it easy to open and close the door.
Oh, I've also experienced the issue of the door sill getting dented. Last time I scraped against the curb, the sill got dented in a spot, which was really upsetting to look at. First, I drove the car to a car wash to thoroughly clean the dented area, as leaving dirt and sand can easily lead to rust. Small dents can be pulled out yourself using rubber suction cups sold online, but forcing it might damage the frame, so I ended up going to a repair shop. The technician said the key to repairing the sill is rust prevention. After using metalworking tools to pop out the dent, they first sand off the old paint, then spray three layers of rust-proof primer to cover the metal layer, and finally restore it with color-matched paint. It's been over a year now, and there's no sign of rust at all. I suggest you don't delay, especially with summer rains coming, it's better to deal with it quickly.
My friend's car had the same issue. The mechanic said the door sill beam can't be directly replaced like a bumper—metal structure deformation requires professional repair. First, assess the deformation level: shallow dents can be fixed with body pull tools in five minutes, while deep dents may require cutting and welding new steel sections. The key is rust prevention! After sanding, apply epoxy anti-rust paint immediately to seal out air—exposed metal can rust through in two rainy days. Post-repair, get a wheel alignment, as sill beam deformation affects door sag angle, causing long-term issues with hinges from improper closing. I recommend choosing a shop offering lifetime rust-proof warranty—worth the extra 300-400 yuan.
