What are the many small black dots on a car?

Small black dots serve purposes such as sunshading, protecting the front windshield, and beautifying the edges of car glass. Below is an introduction to the functions of these small black dots on cars: 1. Protecting visibility: They help reduce glare from sunlight, allowing drivers to maintain clear vision while driving. 2. Protecting the windshield: When sunlight directly hits the windshield, it causes thermal expansion and contraction. The small black dots help protect the windshield by reducing the intensity of direct sunlight exposure. 3. Decorating the car: The small black dots also serve an aesthetic function, making the edges of the car glass look more appealing and less monotonous.
Those small black dots on cars are often rust spots or environmental pollutants sticking to the surface, especially after prolonged outdoor parking where wind, rain, or industrial dust can accumulate. Last time, I found a cluster of small black dots on my car roof, and upon closer inspection, they turned out to be dried tree sap or bird droppings. If left untreated, they can gradually corrode the car paint and affect the overall appearance. I solved the issue by gently wiping them off with a clay cleaning bar, while also applying regular waxing to prevent recurrence. Developing a good habit of checking the car body weekly helps avoid major problems, saving both money and hassle.
The small black spots on the car body are mostly caused by air pollution particles or tar deposits. They become particularly noticeable when the car is parked for a long time in the city or near industrial areas. I used to think they were tiny insects, but later realized they were the result of accumulated dust and chemicals. If not removed promptly, they can damage the paint layer. It is recommended to use a neutral car wash solution with a soft cloth to clean them as soon as possible. When parking, try to choose shaded areas or places with carports to minimize direct exposure to environmental pollution. Long-term neglect may lead to discoloration of the paint or the spread of rust.
