Car paint is like a layer of “skin” on the exterior of a car. When the “skin” is well maintained, it will look radiant. Although it will not affect the performance and safety of the car, once it is “shattered”, this kind of headache “skin disease” does require a lot of effort to “treat”. Here are five very targeted “treatments”. Treatment plan”:
I. Oxidation of car paint
Perennial exposure to sunlight is the main reason for shortening the life of car paint. Ultraviolet rays in sunlight can eventually cause oxidation of car coatings. If there are still water droplets hanging on the car body when it is exposed to the sun, the rate of oxidation will be much faster.
Response: How to deal with car paint oxidation? If it is slightly oxidized, it can be removed with wax. Once the oxidation is serious, it must be ground and polished.
Second, cracked paint
If your car is painted with metallic paint, you should pay attention to prevent the cracking of the paint. This is a very fine crack that will continuously penetrate the paint until it “breaks through” the entire paint layer. The initial stage of cracking is difficult to detect with the naked eye. It is more serious when it can be detected by the naked eye. When waxing and polishing, you will find that the body has streaks, which is due to the presence of car wax in the cracks. Due to the quality of the spray paint, the resin in the car paint will also crack due to “shrinkage”. This “skin disease” can only be cured by repainting.
Countermeasures: Frequent waxing is a good way to reduce the occurrence of cracks. When the cracks are still in the “budding” stage, wax can throw away the cracks that are invisible to the naked eye.
Third, car paint fading
Fume and pollutants in the atmosphere are the main causes of car paint fading and discoloration, especially in industrial areas and in big cities. Fading and discoloration generally occur on the front cover, roof and trunk lid of the car body. This kind of fading is different from oxidation: when oxidized, the whole body becomes black and white, and when it fades, the paint appears uneven color difference. The fading of metallic paint is caused by the corrosion of aluminum foil in metallic paint by acid and alkali in dust and rain. Color paint is a change in color due to the chemical reaction between the pigment in the paint and the above-mentioned pollutants, and sometimes corrosion marks appear.
Response: To prevent car paint from fading, frequent waxing is of course essential. In addition, frequent car washing can also reduce fading disease. Slight fading disease can be treated by waxing and polishing. Moderate fading can be treated by grinding, and must be repainted in severe cases.
Fourth, car paint water marks
Almost all kinds of car paints may have water marks, or water marks. The water mark pattern is ring-shaped, which is the trace left by the evaporation of water droplets. The chemicals in the water marks will continue to chemically react with the car paint when the car body heats up under sunlight, thereby aggravating the “illness”. Cars that have been oxidized, cars that are often washed, and cars that have cracks are more likely to contract water marks.
Corresponding measures: When the water marks are mild, waxing and polishing can be removed, and when they are serious, grinding or painting is required.
V. Paint corrosion marks
What is the difference between corrosion marks and water marks? The water mark phenomenon occurs in a circle of the water droplet, which is annular, while the erosion mark is a piece of the entire water droplet, not a circle. Bird and insect relics, leaves, and tar pitch can all cause etch marks, which can chemically react with the paint and begin to penetrate. They penetrate much faster than water marks.
Countermeasures: Generally, paint can only be removed by spraying paint, and only very slight ones can be solved by grinding and polishing. A high-grade wax finish is often used to help prevent etch marks from appearing.
