Why do you need car paint maintenance?
1. The main components of car paint are resin, petroleum grease, metal and many other elements. The chemical characteristics (strong activity) of these components determine that they are easy to be oxidized and deteriorated, which makes the paint surface easy to be oxidized. On the other hand, car paint contains a lot of water, which will slowly evaporate after sunlight, reducing the gloss and transparency of car paint.
2. External factors will accelerate the oxidation process of paint surface, such as (ultraviolet), dust (mainly iron powder), scraping of hard objects such as branches, bird droppings, insect droppings, acid rain, scale, gum, air-conditioned water, lampblack, flying paint, improper care and so on. The oxidation of car paint begins from the factory, which is closely related to the nursing methods and the use environment. In the mild oxidation state, it has little effect on the overall beauty of the car.
However, when it is moderately oxidized, not only will the color of the car paint be obviously darkened, but people will recognize it as an "old car" at a glance, and its value will be greatly reduced. When deeply oxidized, it will enter the weathering state. After weathering, the chemical structure of car paint will be destroyed, greatly reducing its flexibility and adhesion. When the car paint expands with heat and contracts with cold, it will crack and peel, and eventually it will completely lose its decorative and protective properties. There are many measures for car paint maintenance, such as car waxing, car glaze sealing and car painting. Car painting is the most popular measure for car paint maintenance. Through automobile painting, oxidation can be avoided, and multiple effects such as brightening, acid and alkali resistance, oxidation resistance and ultraviolet resistance can be achieved. Because the material of the film itself is inorganic, it has no damage to the car paint.
Maintenance method of automobile paint surface
First, paint surface cleaning
After the car paint is used, there are often substances such as oil stains, asphalt, bird droppings, dust, acid rain, etc., which adhere to the car paint for a long time. Coupled with the high temperature in summer, it is difficult to wash off these mixtures with water. Therefore, if you want to completely remove the stolen goods attached to the car paint, you need a professional remover, which will not damage the car paint, which is convenient and easy. Don't use cheap disassembly tools.
Not only can it not be cleaned, but it may also corrode the car paint. Second, polish
After thoroughly cleaning the car body, it needs polishing. The function of polishing is to maintain the damaged paint surface. How many times does a car need polishing? If it is a new car, just polish it once and then seal the glaze. For an old car, you can do it several times to make it as bright as new.
Third, sealing glaze.
Polishing is the most important part of the whole maintenance. Sealing glaze will form a transparent hard film on the paint surface, which can improve the scratch resistance, oxidation resistance and high temperature resistance of the car surface and prolong the service life of the car paint. Therefore, the sealing glaze can protect the surface of car paint well and the price is relatively expensive. The quality of sealing glaze also determines the durability of paint in the future.
Fourth, waxing
Usually, car owners confuse waxing with glaze sealing, and waxing can actually improve gloss.
Make the paint look more dazzling. Car wax itself is easy to decompose, with short life, no hardness, no friction resistance, and its hardness and scratch resistance are not comparable to those of sealing glaze. Misunderstanding of automobile paint maintenance
1, often washing cars in street shops.
Some car owners think that there is little difference between car washing in street shops and car washing in professional beauty shops. Actually, no,
Because cheap cleaners used in street shops are usually very alkaline, and the water used is not necessarily clean. Although it can also clean the car body, it will do great harm to the paint surface of the car. I am too lazy to wash the car in rainy days.
Now the air pollution in the city is very serious, and it often rains acid rain, which is very corrosive to the car body. Therefore, car owners should not think that they can be lazy without washing their cars in rainy days. In fact, on the contrary, they need to wash their cars frequently.
3, the new car does not carry out paint care.
The new car is really in the best condition, but the paint maintenance should start from the day when the new car leaves the 4S shop. The traditional Chinese medicine regimen of "three-point treatment and seven-point support" is also applicable to new cars. When you get a new car, the paint is the easiest thing to damage. Generally, there are small scratches, scars on the paint surface and white scars. That's a scraped paint surface. There is no need to touch up the paint. Light, use sand wax or wax more often. If it's heavy, just polish it.
