What is Overspray?
2 Answers
Overspray refers to paint that splashes onto adjacent components during the painting process, which can serve as direct evidence to determine whether a car has undergone paint repair. The paint surface of a car body is highly susceptible to damage, and if the paint surface is damaged, it requires painting repair. The paint surface of a car body is relatively complex, consisting of four layers from the inside out: the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. The consequences of not treating overspray are quite severe; if left for a long time and allowed to dry, it becomes very difficult to remove. The presence of overspray also significantly affects driving visibility. It is advisable to visit a professional auto repair shop or a 4S store for polishing treatment.
When I first bought my car, I encountered the issue of overspray. It refers to tiny paint particles that splatter during the automotive painting process, forming small spots. For example, when painting is done in a repair shop, these paint particles can drift onto other parts of the car body, leaving star-like imperfections. I remember the first time I washed my car, I noticed small particles on the fender and initially thought it was dust that couldn’t be wiped off. Later, I learned it was overspray that had solidified and adhered to the surface. To remove it, you need professional clay bars or polishing wax, gently rubbing to clean it off, but be careful not to damage the original factory paint. I advise friends to regularly check around window edges and wheel hubs when washing their cars, as these areas are most prone to overspray. During painting operations, try to stay away from the vehicle or choose a windless environment to significantly reduce the occurrence of overspray. If discovered, address it promptly to avoid oxidation and erosion of the paint layer.
