Although car paint has little impact on the overall performance of the car. But as the face of cars, car enthusiasts should still learn to protect them. In daily life, paint killers are ubiquitous, such as the natural oxidation of paint surfaces, automobile exhaust emissions, and the presence of iron powder in the air.

Car paint maintenance tips are all dry goods!

Common issues with paint surfaces:

Paint loss of gloss: natural oxidation causes loss of gloss, shallow scratches cause loss of gloss, and perspective effects cause loss of gloss.

Paint oxidation: When the car is exposed to ultraviolet radiation from the sun, the paint film continuously evaporates oil into the air to protect itself. Over time, it can cause excessive loss of oil on the paint surface. The brightness of the paint surface is greatly reduced, causing it to gradually turn white, forming an oxide layer, and shortening the lifespan of the car paint. The naked eye can observe the phenomenon of black, white, and dull paint on the car. Severe oxidation can be treated by grinding and polishing. My car generates a strong electrostatic layer due to friction during driving. Static electricity has a strong adsorption capacity for dust, oil, and chemical dust, forming a hard traffic film over time. Easy to cause oxidation and corrosion on the paint surface, which can be ground and polished.

Cracking: If necessary care is not taken on the paint surface during normal times, the metal paint may produce a very fine crack, which will continue to be applied until it "breaks through" the entire paint layer. This phenomenon is called "cracking". Sometimes due to quality issues with repainting, cracking can also occur. If there is wax in the crack, a striped (trailing) cracking phenomenon will be found on the vehicle body. Frequent waxing can reduce the occurrence of cracking.

Fading: Oil fumes and pollutants in the atmosphere are the main causes of paint fading and discoloration. Fading is different from oxidation. When fading occurs, the car paint exhibits uneven color differences. Moderate to mild fading can be treated by grinding and polishing, and in severe cases, repainting is necessary.

Erosion marks: Erosion marks are surface abrasion. Insects, bird droppings, tree sap, tar, and asphalt can all cause erosion marks. Only slight grinding can be used.

Shallow scratches: Due to friction during use and improper daily care, slight scratches appear on the paint surface of the car over time without exposing the primer. These scratches are particularly noticeable in sunlight. The commonly used polishing method can be removed.

Water mark pattern: The water mark pattern is circular in shape. It is the mark left by the evaporation of water droplets, and cars that are oxidized and commonly cleaned with detergent are more prone to getting water mark disease. When the water marks are slight, waxing and polishing can be done; In severe cases, grinding or painting is necessary.

Daily maintenance of car paint surface

Before, during, and after the use of the vehicle, it is necessary to promptly remove dust from the vehicle body and minimize the adsorption of static electricity on the dust.

2. Rinse promptly after rain. After rain, the rain stains on the car body will gradually shrink, causing the concentration of acidic substances in the rainwater to gradually decrease. If the rain stains are not rinsed with water as soon as possible, it will damage the topcoat over time.

3. When washing the car, it should be done after the engine has cooled down. Do not wash the vehicle in the scorching sun or high temperature to prevent the cleaning agent from drying and leaving traces. Normally, it is necessary to use specialized detergents and neutral running water to wash the vehicle yourself. Alkaline laundry detergent, soapy water, and detergent should not be used to prevent the grease from the paint surface from being washed away and accelerate the aging of the paint surface.

4. When cleaning the vehicle, a clean and soft cloth or sponge should be used to prevent the mixing of metal shavings and sand particles. Do not use a dry cloth, towel, or sponge to clean the vehicle to avoid leaving scratches. When wiping, it should be gently wiped from top to bottom in the direction of the water flow, and should not be circled or wiped horizontally.

5. For some special corrosive traces. To avoid damaging the paint surface, it is necessary to clean it with a dedicated cleaning agent and do not use a blade to scrape or gasoline at will.

Generally, minor scratches, such as scratches on the paint surface, whitening of the scratches, or even if the paint surface is scratched into a hairline shape, are not necessary for repainting. Light, can be treated with car wax; Heavy, just polish it.

For more severe cases, the color of the underlying primer can be seen. Generally speaking, the bumper, rearview mirror, and wheel arch are plastic parts that will not rust. If the problem is small, it doesn't matter if the paint is repaired or not. If it scrapes onto the steel plate of the car body, it needs to be repainted. Otherwise, even if it is a small damage, the steel plate will start to rust, and even the repainting effect will not be ideal at that time.
