Is it necessary to repaint the entire door for touch-up?
2 Answers
If the damage is not obvious, it's unnecessary to repaint the entire door. However, if the damage is severe, it should be done. Generally, when scratches occur, they often damage the car's primer. In such cases, the metal layer of the car body is directly exposed to the air. If the paint is not repaired promptly, rust will quickly form. If you discover small scratches and cannot determine their depth, there's no need to repaint the entire area. Below is a detailed introduction to touch-up methods: 1. If the paint surface is not damaged: Use toothpaste and a cloth to wipe it. If the scratch can be wiped off, that's sufficient. If not, you can go to a repair shop for polishing treatment using a polishing machine and polishing wax. 2. For shallow marks: Use a touch-up pen for paint repair. This method is highly practical. 3. If the primer is exposed: Go to a repair shop for repair and repainting. This will make the car's appearance look neater. Additionally, with current techniques, the color difference after repainting is usually minimal.
Door touch-up painting doesn't necessarily require a full repaint - it depends on the size and location of the scratch. If it's just a small dot or a shallow scuff, a local touch-up will suffice, being both affordable and quick. I've handled such minor issues on my own car before - just using a small paint pen to dab it. However, if the scratch is deep or covers a large area (like half the door), partial repair might result in noticeable color differences, making it look patchy. In such cases, a full respray would be the best choice to ensure uniform color consistency. Additionally, door color aging affects the outcome - older car colors may be harder to match, making a complete door repaint the more aesthetically pleasing option. To save money, try local touch-up first and consider full repaint only if unsatisfactory. Always choose a reputable repair shop - don't compromise your car's appearance for convenience. Regular waxing to protect the paint surface can also reduce the chance of scratches - this method is quite practical.
