Car paint has little effect on the overall performance of the car, but it is dominant in the aesthetics of it. Paint finish killers are everywhere, such as iron powder in car emissions and the air, natural oxidation and other factors. Then how should the car owner maintain the paint based on its condition?
- Paint surface oxidation
Under the ultraviolet rays of the sun, the paint film continuously evaporates oil into the air to protect itself. Over time, the oil in the paint will be overly dispersed. The brightness and depth of the paint surface are greatly reduced, making the paint surface gradually white, forming an oxide layer and shortening the life of the car paint. The appearance of black, whitish and dull paint can be observed by naked eyes. Severe oxidation can be treated by grinding and polishing.
- Traffic “membrane”
When the car is running, a strong electrostatic layer is generated due to friction. Static electricity has a strong ability to adsorb dust, oil and chemical dust, so it will form a hard traffic film over time. It is easy to cause oxidation and corrosion of the paint surface, which can be treated by grinding and polishing.
If the paint surface is not treated with some necessary care, the metallic paint may produce a very fine crack, which will continuously penetrate the car paint until it “breaks through” the entire color paint layer. This phenomenon is called “cracking”. Sometimes due to the quality of heavy spray paint, cracks may also occur. If there is car wax in the crack, you will find that the car body has streak-like cracks. Frequent waxing can reduce cracking.
The fumes and pollutants in the atmosphere are the main reasons for the fading and discoloration of car paint. But fading is different from oxidation. When fading occurs, the car paint has uneven color difference. Moderate and mild fading can be treated by grinding and polishing. In severe cases, paint must be repainted.
- Corrosion marks
Erosion marks are surface abrasion. Insects, bird droppings, tree sap, tar and asphalt may all cause corrosion marks. Only very slight ones can be solved by grinding and polishing.
- Shallow scratches
Due to friction during use and improper daily care, slight scratches appear on the paint surface of the car over time but the primer may not be exposed. Such scratches are obvious in the sun. Generally, it can be removed by professional polishing methods.
- Water mark lines
The water mark is ring-shaped. It is the traces left by the water droplets evaporating. Oxidized cars and cars that are often washed with detergent are more likely to get water marks. When the water mark is mild, it can be cured by waxing and polishing. But when it is severe, grinding or painting is required.
