Reasons for Car Paint Not Being Smooth Like Matte Finish?

Car paint that is not smooth like a matte finish can be treated with polishing and glaze sealing. Here are the specific details: 1. The reason car paint is not smooth like a matte finish is due to the formation of an oxidation layer on the car body, which needs to be addressed promptly: Perform polishing on the vehicle, followed by glaze sealing. This not only resolves the issue of rough car paint but also generates a new paint film, restoring the car's shine. Polishing is a method that uses polishing wax and a polishing machine to remove surface scratches and rough areas on the car paint, effectively grinding away the aged paint film. 2. The car paint surface is contaminated with many harmful substances, leading to a rough texture, which requires cleaning: First, use water or car wash liquid to clean the dirt adhering to the car body. Then, use a clay bar soaked in warm water to gently wipe the car paint while spraying water. After using the clay bar, applying wax can protect the car paint and enhance its gloss, making it appear more vibrant.
I'm all too familiar with car paint becoming rough like matte. Having been into cars for years, I've identified several common causes: First, improper washing techniques, like using rough sponges or stiff brushes to scrub the car vigorously, which over time scratches and roughens the paint surface. Second, aging factors - prolonged exposure to wind and sun causes UV rays to oxidize and peel the paint layers, while airborne dust particles settle on the surface creating that matte texture. Third, pollution effects - parking roadside exposes the car to exhaust fumes or industrial particles that adhere to the surface, combined with acid rain erosion that dulls the paint. I believe the key is daily paint protection - never cut corners with careless washing, always use soft microfiber cloths with professional car shampoo. Regular waxing can also prevent this roughness - applying wax quarterly makes it much less likely to occur.
At my age, I've seen many car paint issues. The unsmooth, matte-like texture is mainly due to the passage of time. My old buddy once told me that after a few years of use, the paint surface naturally becomes coarse, especially when parked in an open space exposed to daily sunlight, wind, and rain, causing the paint layer to gradually peel off. Another major reason is careless washing—using ordinary mops to wipe the car can easily leave fine scratches, turning it matte. It could also be due to poor paint quality; if the factory paint on a new car isn't fully dry before polishing, the surface ends up rough. It's just like how human skin becomes rough with age—it needs gentle treatment. I recommend avoiding high-pressure water guns to prevent damaging the car paint.
