What to Do About Dust Spots After Painting?

First, use 3M 2000-grit sandpaper, typically in a 2-cut size, fold it in half and then separate it along the fold line. Use the soft side of the sanding block to evenly sand the dust spots on the paint (i.e., the imperfections in the paint) until there is no noticeable resistance on the paint surface. Then, apply 3M 05973 medium-coarse polishing compound. Next, use a polishing machine at a speed of 2000 to 3000 RPM to polish until the paint regains its gloss. Visit the brand service station of your vehicle to have the paint redone. If there are any noticeable imperfections, you can also request them to be addressed, as the service quality at the station is generally better.
When encountering dust spots after spray painting, I think this is a common annoyance many car owners face. Last time I had my car touched up, I noticed a few small spots that looked particularly unsightly. The usual cause is dust particles floating in the air during the painting process sticking to the paint surface. For post-treatment, you can gently sand the spot with fine sandpaper above 1500 grit to remove the raised area, clean it, and then cover it with a touch-up paint pen; or polish it to restore the gloss. The key to prevention is to thoroughly clean the environment before painting: wipe the car surface clean, close doors and windows to minimize dust entry; it's best to perform spray painting in a dust-free, wind-controlled indoor space. I recommend friends not to overlook this step, otherwise, repairs might require troublesome rework and unnecessary extra costs. Overall, car paint maintenance requires attention to detail to keep the body looking good and extend its lifespan.
Dust spots after DIY car painting are quite common. I believe the key lies in process control: thoroughly clean the work area and vehicle surface before painting, using dust removal cloths for wiping; avoid stirring up dust during the painting process. If spots have already appeared, wait for the paint to dry, then carefully sand them smooth with ultra-fine sandpaper (such as 2000-grit) using water, followed by a polishing machine or hand polishing cloth to restore the gloss; larger spots may require touch-up paint. In terms of tools, having a good spray gun can reduce issues. Preventive measures: choose overcast days or indoor painting for better results, and regular maintenance to avoid major repairs. This approach is generally effective, and maintaining the car's appearance is crucial.
