Repainting is not necessary for a scratched fender. If the fender only has paint damage without any dents, simply applying putty and repainting will suffice. However, there is one situation where a full repaint is recommended: when the vehicle has a special color. This is because partial repainting of special colors can easily result in color discrepancies, affecting the vehicle's appearance. Notes on car scratches: 1. New cars: It's best to repair scratches on new cars as soon as possible, otherwise it may affect the car's aesthetics. 2. Polisher: For minor scratches, use a polisher but avoid excessive grinding, as it can damage the painted surface. 3. 4S shops: For more severe damage, it's advisable to go to a 4S shop for repair.

I have to say, it's best to touch up the paint if the fender is scratched. Since it's near the wheels, it's prone to getting wet from water and rain. If the scratch is deep enough to expose the metal, it won't take long for rust to form. Once rust spreads, it can corrode the entire body structure, and repairing that can be very costly. I once ignored a small scratch, and half a year later, the fender rusted through, forcing me to replace the whole thing, costing me several thousand extra. If the scratch is shallow and only the surface paint is affected, you can use a touch-up pen to fix it yourself. But if it's deep enough to feel rough to the touch, you'll need to take it to an auto repair shop for sanding, filling, and repainting, which might cost a few hundred to a thousand yuan. Don't underestimate this area—it may not be very noticeable, but the hidden risks are significant. Make it a habit to check during car washes and address any issues promptly to save a lot of trouble later.

If the fender is scratched, you don't necessarily have to repaint it—it depends on how severe the scratch is and how deep your pockets are. For minor scratches like a line that hasn't exposed the primer, you can actually ignore it since it doesn't affect driving safety. Repainting would just be a waste of money; a touch-up pen and applying it yourself can save you hundreds. However, if the scratch is deep enough to expose bare metal, you should repair it immediately. Otherwise, rust will set in, making repairs more expensive and potentially damaging other parts. When I drove an old car, I was lazy—I ignored small scratches since it was just a used car anyway. But for a new car, consider fixing it to maintain its appearance and resale value. Do the math: minor touch-ups cost just a few dozen bucks, while major repairs can run into thousands. You'll need to weigh your car's condition and your budget.

The fender is above the wheel, and scratches are quite noticeable, especially on dark-colored cars, where scratches leave obvious marks that look unpleasant. For minor scratches, using a touch-up paint kit is a low-cost DIY solution. For deeper scratches, it's advisable to get them professionally repainted—not just for aesthetics but also to protect the car from rust. As a car enthusiast, I believe maintaining the exterior is important; leaving scratches unrepaired makes the car look aged over time. However, there's no need for drastic measures—if it's just minor paint damage that doesn't affect driving safety, you can wait. After repainting, the fender becomes smoother, making car washes easier and preventing dust buildup that could lead to corrosion. In short, prioritize aesthetics based on the severity and urgency of the damage.

A small scratch on the fender is nothing to worry about. As long as the metal isn't exposed or dented, it's still safe to drive, and there's no rush to repaint. I've been driving for over a decade and minor scratches and dings don't bother me—the fender's location isn't a big deal. Of course, if it's a deep scratch exposing metal, then it needs repair to prevent rust from spreading and affecting the frame's lifespan. Just remember to dry water stains after washing to reduce rust risk; small scratches can be buffed with toothpaste or a coating—cheap and easy. Keep in mind the fender isn't a critical part, so no need for excessive repairs unless it bothers you aesthetically.

Previously, a large section of my car's fender was scratched, exposing the primer, which required immediate repainting to prevent rapid rusting. The fender area tends to accumulate water, and deep scratches can lead to rust when it rains, making corrosion spread difficult to manage. For minor scratches, you can try using a touch-up pen or coating, but the results are usually mediocre. Professional shops do a better job, costing a few hundred dollars to fix. If left unrepaired, the appearance deteriorates over time, reducing the car's resale value. The rule of thumb is: check if the metal is damaged—if yes, repair it; if not, you can delay. Regular includes inspecting the fender periodically to prevent issues proactively.
