How to Solve Severe Paint Peeling on Car Doors?

Solutions for severe paint peeling on car doors: Repaint the affected area, ensuring to select paint that matches the original color and opt for high-quality brands. Paint maintenance is crucial and plays a key role. After the initial wax removal, the new car's body is exposed to the air, making it susceptible to damage from windblown sand, acid rain, and harmful substances like carbon black from vehicle emissions, which can lead to paint oxidation. Common paint maintenance services currently include waxing, glaze sealing, coating, and crystal coating, each with its own characteristics. For new car paint, glaze sealing or coating is unnecessary, and immediate waxing is also inadvisable because new car paint comes with a protective wax layer. Performing these maintenance tasks right after purchase can damage the original protective layer, wasting money and potentially not achieving better results than the original protection. Therefore, it's sufficient to start waxing the car after it has been used for some time.

My car door had severe paint peeling, with large chunks falling off, which looked terrible. I tried fixing it myself with a touch-up pen, but the color didn't match, and the result was poor. Later, I took it to an auto repair shop, where the technician explained that prolonged exposure to sunlight and rain erosion were the causes. They sanded off the rust and repainted the area, which fixed the issue. It cost around 500 yuan, and now it looks as good as new. I've learned to park in garages or shaded areas whenever possible to avoid direct sunlight and contact with chemicals. Regular waxing can prevent rust and extend the paint's lifespan. These small habits can save money and hassle, so they're worth trying.

As someone who has repaired many cars, door paint peeling is usually caused by scratches, corrosion, or poor original paint quality. The repair process must be done step by step: first, clean the door and sand it smooth to remove rust; then apply filler to level the dents, sand evenly, spray primer, apply matching topcoat, and finally coat with protective paint. Small issues can be fixed with DIY spot repairs, but for large-scale peeling, it's recommended to have the entire door professionally repainted. The entire process takes 2-4 hours, with costs varying by car model and region. For regular maintenance, it's advisable to avoid acidic car wash detergents, park in safe places to prevent scratches, address issues early to prevent rust spread, and ensure driving safety.

Regarding the issue of door paint peeling, I focus on eco-friendly solutions. When repairing, opt for water-based or VOC-free environmentally friendly paint to reduce pollution. Minor touch-ups can be done by yourself, but professional services are more reliable. Prevention is even more crucial: use biodegradable car wash soap and choose natural wax products to avoid damaging the paint. In the long run, protecting the car door well reduces resource waste from replacements; dealing with rust later is troublesome and costly, so it's better to act early. Remember, simple cleaning and sunshade measures can also help a lot. Being environmentally friendly starts with daily habits.

I enjoy DIY repairs for car door paint chips. Purchase a touch-up paint kit, clean the door, then sand it smooth with sandpaper. Apply filler putty and let it dry for 30 minutes before sanding it smooth again. Next, spray on primer, let it dry, then apply color paint in two thin coats with a 15-minute interval between them. Finally, add a clear coat for protection. The cost is just a few dozen yuan, but it requires patience and attention to detail. The improvement in appearance is noticeable after completion. For regular maintenance, avoid parking under trees to prevent bird droppings from corroding the paint, and use a soft cloth to gently wash the car. These small habits can prevent paint chips and save both money and hassle.
