Car paint maintenance Care in the rainy season is careful of three misunderstandings

It is understood that the current automotive paint care process has developed to the fourth generation. The well-known “waxing” and “polishing and waxing” belong to the first and second generation of paint care processes, while the new processes such as “glazing” and “coating” belong to the third and fourth generations. Various processes have their own advantages and disadvantages, and car owners need to choose according to the situation of the vehicle.

Waxing: Use car wax with a large amount of water

Waxing is the most commonly used paint care method at present by polishing the fine scratches on the paint surface to achieve the brightness of the paint surface. Its main function is to prevent the oxidation of automobile paint and maintain the gloss and texture of the paint surface. In terms of use, the current automotive waxes on the market are mainly divided into two categories: decontamination wax and protective wax. Generally speaking, dark-colored vehicles only need to wear protective wax, while for light-colored vehicles, car beauty experts recommend that the impurities be removed by removing the dirt wax first, and then applying protective wax to avoid paint defects.

Condition: If you feel that the body is not smooth when you touch it, or if you find that the color of the body is dull, it is time to wax the body.

How to wax: From the perspective of waxing process, it is divided into manual waxing and machine waxing. Generally speaking, the machine waxing is relatively uniform, and the effect is better; Although the uniformity of manual waxing is not enough, it can wax the edges, corners, edges and other places that cannot be covered by machines. Experts warn car owners that manual waxing should not be carried out in the open air under strong light and high temperature, otherwise the effect of waxing will be greatly reduced.

Advantages: Compared with the other three paint care methods, waxing is more convenient and simple, and the owner can complete the waxing of the whole vehicle by himself. In addition, the price of waxing is also relatively cheap, and a box of medium-priced car wax costs more than 100 pieces.

Disadvantages: Lack of durability is the most prominent disadvantage of waxing. Generally speaking, one waxing can only withstand about 15 washes, and car owners need to wax three or four times in a month. In addition, due to the characteristics of the product, the wax layer of the body is difficult to stack, and the thickness of the wax is limited.

Pro tip: As the seasons and weather change, car owners should also choose different car waxes. When the rainy season comes, you should choose a car wax with a large amount of water to avoid the accumulation of rainwater on the body and cause oxidation of the paint. In addition, when summer and autumn come, it is best to choose anti-ultraviolet and high-temperature car wax, which can also play an anti-oxidation role.

Polishing: After polishing, wax needs to be re-applied

Conditions: If waxing is the daily care of the car, polishing is a “big action”, which is aimed at the scratches that do not see the paint bottom, the matte color of the body (that is, the color of the body changes), and the paint surface has obvious concave and convex feelings.

How to polish: Generally speaking, polishing is divided into water sandpaper grinding, machine polishing, brightening, mirror restoration and other processes. In the polishing process, it is necessary to choose three kinds of coarse wax for polishing, such as fine, medium or heavy cutting, according to the severity of the damage to the paint surface of the car. After polishing, the owner is usually advised to wax (i.e. the aforementioned waxing) to better protect the paintwork.

Features: In fact, polishing is to polish off the surface of the contaminated or damaged paint layer, so the polished paint layer will become thinner, and the toughness will also become worse, it is not recommended to use.

Pro tip: Car owners should pay attention to the usual paint care and don’t wait until something goes wrong to carry out maintenance.

Sealing glaze: the deep damage to the paint surface is greater

Glazing is a solid protective layer that presses the glaze (polymer) into the inside of the paint through a special vibrating and polishing machine to form a network. The paint surface is like human skin, full of capillary-like pores, and the water in the car paint can be volatilized through the small holes under strong light or high temperature, making the paint age. After the glaze sealing, the polymer can penetrate into these pores, thereby preventing the volatilization of Tiannashui.

Condition: Before coating, it must be ensured that the body paint is smooth and clean.

Advantages: The glaze can isolate the paint surface from the air, and has the functions of ultraviolet insulation, anti-oxidation, high temperature and acid rain. Moreover, the warranty time of the glaze is longer, and it can be maintained for 8-12 months after doing it once.

Disadvantages: Due to the erosion of the glaze, the car after the glaze sealing treatment can not be changed to waxing or other ways for painting, and can only continue to be glazed sealing. For example, there is a cosmetic product that can make a 25-year-old look like an 18-year-old, but when she doesn’t use it one day, she looks like a 30-year-old. In addition, if the lacquer surface is re-painted after glazing, there will be a phenomenon of “roll-rolling” (paint stripping).

Coating: Good effect and expensive price

Condition: Before coating, it must be ensured that the body paint is smooth and clean.

How to coat: The battery coating is an electrophoresis technology that adsorbs the inorganic film on the surface of the car through the electrophoresis technology of mutual adsorption of positive and negative electrons, so as to form a comprehensive protective layer that is resistant to acid, alkali, wear, ultraviolet and corrosion.

Advantages: Coating is currently the best paint care process. The effect of coating has the same effect as waxing, and multiple layers can be stacked to increase the hardness and durability of the paint surface, and one film can normally last for a month. The material of the membrane itself is an inorganic substance and has no damage to the car paint.

Disadvantages: Due to the use of imported materials, the technology is complex, so the cost is quite expensive, and it takes about thousands of yuan to coat the whole car at one time. In addition, the brightness of the coating is not as good as that of the sealing glaze.
