It mainly depends on the repair method. If the method is correct, there will be no color difference. Here are the reasons why repainting at a 4S shop does not result in color difference: Remove rust: Completely remove rust, dirt, and grease from the paint surface. You can first use very fine water sandpaper dipped in water to gently sand off rust spots, then thoroughly clean to ensure the rust does not spread. Repainting: Use tape around the scratches to prevent the touch-up paint pen from coloring undamaged areas. For better results, you can also use polishing paste to smooth out the scratches and paint surface, enhancing the adhesion of the paint. Use the brush tip that comes with the touch-up paint pen to carefully fill in the scratches on the car body in a dot-like manner. If the surface is still not smooth enough, you can use fine polishing wax to level it out after the paint has dried for about a week.

When it comes to whether there will be color differences in paint repairs at 4S shops, having worked in the automotive industry for over a decade, I find this issue quite nuanced. First, any paint repair may have slight color variations, especially if the car paint has aged or the color is unique, such as red or blue, which require more precise matching. The advantage of 4S shops lies in their advanced equipment—color-matching scanners can read the original paint code and use factory-grade paint, keeping color differences to a minimum. However, prolonged exposure to sunlight and weathering can cause older paint to yellow, making new paint appear more vibrant. I recommend choosing reputable 4S shops, as their technicians are highly experienced. After painting, they test the finish under strong light from multiple angles to minimize discrepancies. Additionally, regular paint maintenance, like waxing to prevent oxidation, can significantly enhance the car’s appearance. Don’t wait for major scratches to get repairs; addressing minor damage early yields better results.

Last time my car got scratched, I went straight to the 4S shop for a paint touch-up. It took some time but the result was quite satisfying. The staff first used a computer to match the color, comparing it with the old paint swatches on the car body. The painting process was meticulous, and in the end, the color difference was almost unnoticeable. I think the advantage of 4S shops lies in the details—for example, they have specialized indoor and outdoor light inspection areas to ensure the paint matches under both sunlight and cloudy conditions. After painting, they also offer a few days of warranty, with free rework if there are any issues. If your car has a dark color or is over three to five years old, the new paint might be slightly brighter, but it still blends well overall. Remember to check reviews when choosing a shop and communicate your expectations in advance. After the touch-up, don’t rush to wash the car—wait a week for the paint to set properly. This experience has made me trust professional services even more.

To minimize paint touch-up color discrepancies, choosing a 4S store is the right decision. Their color-matching equipment is precise, the paint comes from the same source as the original, and the spray gun ensures even coverage. The process also includes multiple layers of quality control. Pay attention to the car's condition: newer cars have less color difference, while older cars may show slight discrepancies due to faded paint, but it's not noticeable. Communicate your requirements clearly and opt for certified technicians. After the touch-up, check the reflection from multiple angles to confirm. Maintain your car's paint health by avoiding frequent scratches and acid rain erosion to ensure long-lasting results. Don't skimp on costs by going to small shops; professionalism brings peace of mind.
