How to Deal with Small Dots After Car Painting?
3 Answers
While driving, the car body is easily scratched by flying stones or roadside branches, causing damage to the paint surface. In such cases, it is necessary to visit an auto beauty station for repair. During the touch-up painting process, due to uneven spraying and dust on the car body, some tiny particles may appear around the painted area, which can affect the overall appearance of the car. If small particles appear after the car is repainted, it still has a certain impact on the vehicle's appearance. After touch-up painting and polishing, the paint layer becomes thinner, so it is essential to have the staff apply another coat of paint. If the small particles are caused by dust settling after the painting is completed, these particles can be removed through polishing, and the finish will match the original gloss. However, if the particles are due to inadequate paint filtration during the painting process, polishing alone will not be sufficient to remove them. In such cases, the staff must re-sand and repaint the affected area.
It's really frustrating when you notice small particles in the freshly painted car finish. I've specifically researched this issue and concluded that it's mostly due to an insufficiently clean painting environment, where dust settles on the car body and hardens. Don't rush to repaint it immediately. First, gently sand the surface with 2000-grit sandpaper, making sure to go in one direction and not in circles. Once the paint becomes matte, wash it thoroughly at a car wash, then use a polishing machine with coarse wax, applying it evenly in two passes. This kind of minor job can easily be done by yourself, saving you the hassle of taking it to a repair shop. The key is to avoid opening windows for three days before painting to minimize dust, which naturally leads to better results. After treating my old car this way, it now feels as smooth as a mirror—it's actually not as difficult as you might think.
Last time my car had tiny speckles all over after being painted at the repair shop, which really upset me. The shop said it was caused by impurities in the paint or inadequate filtration in the paint booth. I insisted they redo it. The technician first used fine sandpaper to locally sand down the bumps, then applied a thin layer of clear coat, and finally polished it to restore the original appearance. The key to this issue is that the painting environment must be sealed and dust-free, and the technician's technique must be steady. It's recommended to check the paint under light after it dries completely. For small areas, you can buy some car wax and sand it down to fix it. If a redo is necessary, remember to watch the workers clean the spray gun, otherwise you might face the same issue again.
