How to Repair a Hole in the Rear Fender?
3 Answers
This depends on the specific situation. If the hole is relatively large, it is recommended to go to a 4S shop for replacement. If it is not particularly severe, welding repair can be performed. Relevant introduction to car fenders: 1. Definition: Car fenders are designed based on the tire model used by the car. The car's wheels have a steering function to ensure space during rotation. The front and rear fenders used in cars are different, and for aerodynamic considerations, the rear fender commonly has an outward convex arc. 2. Function: The fender can reduce the wind resistance generated during the car's movement, which helps with the car's stability. The fender also plays a role in protecting the chassis.
I've repaired this kind of hole several times. It's recommended to first check the extent of the damage. If the hole is small, it can be patched, but if it's large, the entire fender needs to be replaced. The standard procedure is to go to a repair shop for an assessment: the technician will remove the fender and check if the internal structure is deformed. If it's metal, they will use a welding torch to repair the hole, fill it with putty, and then sand it smooth. After that, they'll spray paint to match the body color and reinstall it. The whole process requires professional tools and experience; if you try to do it yourself, you might mess it up. After painting, anti-corrosion treatment is also needed to prevent rust. If the hole is severe, don't try to save money—just replace the part directly to avoid affecting the vehicle's safety. After the repair, drive it a few times to check for any unusual noises or looseness.
The moment I saw the hole, I knew I had to take it to a professional shop. The rear quarter panel connects to the frame, and a large hole could mean structural damage—DIY repairs can be dangerous. A professional technician will use machines to assess the damage. For minor issues, they'll weld, fill with putty, and repaint; for serious damage, they'll replace the part. Paint matching must be precise, or the color mismatch will look awful. They should also check for hidden damage, like loose weld points, and fix those. Safety first—never attempt DIY repairs. I tried patching it myself once, and it ended up leaking and rusting. After repairs, get a wheel alignment to ensure balance. Choose a reputable shop and monitor the repair over time.
