[汽车修理知识]Three Needs and Three Don’s for Car Maintenance

Three important points:
1. The body should be inspected regularly.
The most annoying thing about the exterior of the car body is rust, which is mainly caused by the direct contact of the sheet metal metal with the outside world. In addition to the common causes such as collisions, scratches, left alone, and rusting over time, there is also a situation that when driving, the bumps caused by the bounce of the tires of the front car will cause the paint surface to appear one by one. Small flaking spots produce small rust spots. Such small traces are often ignored by people, and the body of the car should be inspected regularly.Engine coverAnd the surrounding areas of the car body, once found, immediately deal with it.
2.carThe paint surface of the early stage should be maintained.
After buying a new car, you should put a layer of mirror glaze on the body. The mirror glaze is mainly composed of high molecular polymer, which acts directly on the surface of the car paint.When glazing, clean the body first, and then usepolisherThe mirror glaze is squeezed into the interior of the paint through vibration to form a strong protective film like a net, which greatly improves the hardness of the paint. At the same time, the characteristics of high temperature and ultraviolet resistance better protect the car paint. If the car is washed and waxed regularly, the mirror glaze effect can be maintained for a year.
3. Put a tube of ordinary toothpaste on the car.
Once you find a small new scratch, just apply a little. After it rains or washes the car, don't forget to apply it again. It can simply act as an insulation and there will be no problem in the short term. This is just a simple way to deal with it. In the end, you have to go to the beauty shop to completely remove it. If you want to save trouble and money, you can wait until there are more similar damages on the car body before intensive repairs.
Three don't:
1. Do not wipe the body with a duster.
Many drivers habitually use a duster to wipe the front windshield glass and dust on the paint surface of the car. This is actually self-deception.There is a large amount of dust in the duster. The owner uses the same duster to wipe the car every day, just like rubbing the car paint with a file, and personally making fine scratches on the car paint; the hair wheel of the inferior car washing machine uses nylon wire and other hard High-quality materials, the wool wheel rotates at high speed when washing the car, which has a strong cutting force on the paint surface; ordinaryCar waxSome abrasive particles are added to the car paint. When the decorator is waxing the car, it will be polished and polished in a circle. The essence of polishing the car paint is the process of polishing the car paint by these invisible particles. Water wax is soft and volatile. It cannot penetrate into the car paint by manual friction. It can only enhance the brightness of the car paint and has no repair function to the gloss of the car paint.
2. Do not cover vehicles parked outdoors.
Once it encounters windy and rainy weather, the wind and rain hit the outside of the car jacket, and the inner layer of the car jacket will repeatedly beat the car paint, making countless small scratches on the car body. These scratches are all over the car. It can't be completely removed by washing or waxing, and it will cause the paint surface to become black after a long time.
3. Do not keep water inside the door.
The places where water is prone to accumulate on the body, such as the inner and outer edges of the wheel arc, the bottom of the door and the luggage compartment, and the corners, etc., are also prone to corrosion after a long time. If the drain on the lower edge of the car door is blocked or not smooth, the water that penetrates during rain or car washing will stay inside the car door for a long time. After a period of time, it will start to rust from the inside to the outside. When it is found, it will be difficult to deal with .
