How to Repair a Car Fender

A car fender is a metal frame that covers or houses a wheel well. Its primary function is to keep rocks, mud, liquids, and other debris from being thrown into the air as the tires rotate during driving.

Fenders can be made of steel, aluminum, or fiberglass. Aluminum is more durable and can withstand high speeds better than steel.

Damaged Fenders

The fender is the most prone to damage on your car since it’s located close to the wheels. This means it’s exposed to the elements, including harsh UV rays and varying weather conditions. If left untreated, these factors can cause the paint to chip or even rust out. Rust outbreaks aren’t just unsightly; they can weaken the overall structure of your vehicle, especially if the fender is bent or dented.

While it’s possible to repair dents on your own, it’s best to leave this task to professionals. This process involves using body filler to build up a damaged area, buffing it, sanding it, and painting it to match the original color of the fender. This step-by-step process can be complicated and time-consuming, especially if you’re not familiar with the process.

Dents on car fenders are not only unsightly but can weaken the metal structure of the quarter panel. This can be dangerous if another accident occurs. Weakened metal may not be able to absorb the impact, and people in the vehicle may sustain serious injuries.

Depending on the size and location of the dents, they can often be fixed using PDR. However, more severe dents can require body filler and repainting to get them back into their original shape. This is a labor-intensive process and requires a lot of experience to make it work well.

Fenders are an essential part of any car as they protect the wheels and the passengers from debris like stones, mud, liquid and other things that get thrown into the air by the rotating tires while driving.

One way to repair dents on your car fenders is to pour boiling water over the dent and its immediate area.

However, this method can only be used so many times as thermoplastics can only withstand so much heat before they deform and discolor.


Fenders are an essential part of your vehicle and protect it from a wide range of damage caused by road debris and rainwater. They also make your car look more stylish and excellent.
