How to Deal with Wrinkling in Paint Spraying?
2 Answers
Introduction to handling wrinkling in paint spraying: When wrinkling occurs during paint spraying, you can add more paint to increase the coating thickness, then allow it to air dry before sanding and polishing with sandpaper. Wrinkling in car paint spraying may be due to improperly mixed paint or issues with the original paint layer or the applied primer. Below are some precautions regarding paint spraying: 1. Choose a reputable auto repair shop: When performing body shaping and paint spraying for your car, select an auto repair shop with a good reputation and skilled technicians. 2. Negotiate the price in advance: If you are not repairing the car at a 4S shop, make sure to discuss the price in advance when going elsewhere for body shaping and paint spraying to avoid various disputes after the repair is completed. 3. Ensure proper body shaping: Car body shaping is crucial; if not done properly, the car's surface may appear uneven, significantly affecting its appearance.
I often encounter the problem of paint wrinkling, which is usually caused by the paint not drying thoroughly, being applied too thickly, or the temperature being too high. To deal with it, I first need to let it dry completely, then carefully sand the wrinkled areas with coarse sandpaper, smoothing out the wrinkles but being careful not to damage the underlying car body. After sanding, blow off the dust, clean the surface, and then sand it smooth with fine sandpaper to ensure there are no uneven areas. Next, apply a thin layer of primer again, wait for it to dry completely, and then apply the color paint, spraying each layer thinly to allow for even drying. I've tried this several times and found that working in a well-ventilated and shaded area yields better results, avoiding direct sunlight that can cause the paint to dry too quickly and wrinkle. If the wrinkling is severe, it may require multiple rounds of sanding and repainting.
