Why is the paint surface not smooth like matte?

If the car paint is not smooth and has a matte surface, it may be due to an oxidation layer on the car body. Polishing and glaze sealing can be performed. Relevant information is introduced as follows: If an oxidation layer appears on the car paint, polishing is required, and the effect will be better after polishing followed by glaze sealing. However, if it is a new car, polishing is not recommended, and coating is better than glaze sealing. Polishing is a method to remove scratches and rough areas on the car paint surface using polishing wax and a polishing machine. Polishing can grind off the aging paint film, allowing a new paint film to form and restore the paint's brilliance. Waxing or glaze sealing after polishing can achieve more ideal results.
The paint on my car has also become rough like sandpaper, which feels very uncomfortable. This is caused by prolonged exposure to sunlight and rain, leading to aging and oxidation of the paint surface, especially when parked outdoors. Dust and air pollutants accumulate on it, forming a rough layer. Using hard brushes or inferior cleaning agents during car washing can also cause fine scratches, exacerbating the problem. From personal experience, parking under trees in summer and not cleaning bird droppings promptly left spots that made the surface even rougher. For prevention, I recommend cleaning the car body with a soft cloth at least once a month and choosing a neutral car wash solution; waxing every quarter to protect the paint surface; and selecting a garage or shaded area for parking to reduce external damage. If the situation is severe, you can seek professional polishing to repair the surface layer, avoiding DIY scratches. Remember, the health of the paint surface not only affects aesthetics but also prevents rust and extends the car's lifespan.
I found that the main causes of a matte paint surface are prolonged exposure to the environment, leading to aging or pollutant buildup. For example, parking near industrial areas allows dust particles in the air to embed into the paint layer, making it feel rough; UV rays from sunlight cause the clear coat to become brittle; improper car washing, such as using old sponges or abrasive cleaners, can scratch the surface. As someone in the automotive industry, I emphasize checking for fine scratches or paint imperfections, as these can worsen the matte appearance. Solutions include professional polishing to remove the contaminated layer or using mild cleaners for regular maintenance. For prevention, avoid rinsing immediately after rain or snow to prevent water spot residue, and develop a habit of regular waxing. The key is addressing minor issues promptly before they escalate. This way, the car can maintain its original glossy finish, saving on repair costs.
