What Causes Small Bumps on Car Paint?
2 Answers
Small bumps on the paint of a newly purchased car are likely caused by dust particles that were not properly cleaned off the surface before painting, resulting in imperfections on the paint finish. Below is relevant information: When picking up the car, first check the odometer reading, which is usually under 100 kilometers. Also, inspect the radiator fins for debris, the integrity of the seat protection packaging, and whether the interior, including the driver and passenger areas and the dashboard, is clean. Additionally, pay attention to the gap between the car's manufacturing date and the pickup date. If the gap is too long, it might be a display or refurbished car. In such cases, check for the presence of tire tread hairs, which are usually clearly visible on new car tires.
I've been driving for over a decade and often encounter small raised bumps on the car paint. These mostly occur when dust or small particles fall onto wet paint during the spraying process, forming tiny bumps. Additionally, when driving on highways, stones or asphalt debris can splash up and hit the car body, drying into raised spots. I've also noticed that parking under trees can cause similar issues when tree sap drips onto the car, especially in hot summer weather when it solidifies easily. For prevention, it's advisable to park in clean environments or use car covers for protection. For newly purchased cars, poor painting quality might also lead to trapped air bubbles or impurities. Regular car washing and waxing can reduce such problems, and in severe cases, professional polishing at a specialized shop is recommended.
