Five common “skin diseases” of car paint and Countermeasures

Car paint is like a layer of "skin" on the exterior of the car. If the skin is well maintained, it will look bright and bright. Although it will not affect the performance and safety of the car, once "breaking the face", this headache "skin disease" really needs to take some thought to do "treatment", and then we will teach you five very targeted "treatment schemes":

1. Oxidation of car paint

The main reason for shortening the life of paint is the sunshine. Ultraviolet rays in the sun will eventually cause oxidation of the car coating. If the body is still hung with water droplets in the sun, the oxidation speed will be much faster.

Countermeasures: how to deal with the oxidation of car paint? If it is slightly oxidized, it can be removed by wax. Once the oxidation is serious, it must be ground and polished.

2. Car paint crack

If your car is metallic, be careful not to crack the paint. It is a very fine crack that will continue to penetrate the paint until the entire paint layer is "broken down". It is difficult to find the naked eye at the beginning of cracking. It's more serious when the naked eye can detect it. When waxing and polishing, you will find that there are stripes on the body, because there is wax in the cracks. Due to the quality of paint painting, the resin in the paint will also be cracked due to "shrinkage". This "skin disease" can only be cured by repainting.

Countermeasures: regular waxing is a good way to reduce cracking. When cracking is still in the "budding" period, wax can discard cracks invisible to the naked eye.

3. Paint fade

The smoke and pollutants in the atmosphere are the main reasons for the discoloration and discoloration of car paint, especially in industrial areas and big cities. Discoloration and discoloration are usually found in the front cover, roof and rear compartment cover of the body. This kind of fading is different from oxidation: when oxidation, the body is black and white, while when fading, the paint of the car appears uneven color difference. The fading of metallic paint is caused by the corrosion of aluminum foil in the metallic paint by dust, acid in rain and alkali. The color paint is caused by the chemical reaction between the pigment and the above pollutants, which leads to the color change, sometimes there will be corrosion marks.

Countermeasures: to prevent the fading of car paint, frequent waxing is certainly necessary. In addition, the field car washing can also reduce the fading disease, and slight fading diseases can be treated by waxing and polishing. Medium fading can be treated by grinding, and repainting must be done in case of serious.

4. Paint water mark

Almost all kinds of paint may have water marks, or water lines. The water mark is circular, which is the trace left after the water drops evaporate. The chemical substances in the water mark will continue to react with the paint when the car body is heated under the sun, which aggravates the "condition". The oxidized car, the car which is commonly used for washing spirit and the car with cracks are more likely to get water marks.

Countermeasures: when the water mark is slight, waxing and polishing can be removed, and grinding or painting is required in case of serious.

5. Paint etch mark

What is the difference between erosion mark and water mark? Water mark phenomenon occurs in a circle of water beads, which is circular, and erosion marks are a piece of the whole water bead, not a circle. Birds and insect remains, leaves, tar pitch can cause corrosion marks, which will react with paint and start to penetrate. They penetrate much faster than water marks.

Countermeasures: generally, only paint can be used to remove paint corrosion marks, only a very slight can be solved by grinding and polishing. The common high-grade wax polish paint can help prevent the appearance of corrosion marks.
