In winter, it is more important to protect the "skin" of cars

The car paint, like human skin, is very fragile. Many things on the car paint surface can scratch it. A series of problems such as cracks will appear if the car paint is not maintained, so we need some common sense of car maintenance.

1. Prevent metal from rusting

Corrosion is mainly caused by the combined action of moisture, oxygen and corrosive substances in the air. Therefore, the metal surface should be kept clean for vehicles that have been suspended for a long time. The garage where the vehicle is parked shall be ventilated frequently to keep the relative humidity of the air below 70%.

The dust, dirt and moisture on the vehicle shall be removed in time. Oil, grease or oil paper shall be applied to the parts and surfaces that are easy to rust. The pores on each assembly mechanism shall be sealed to prevent air, moisture and dust from entering the interior.

2. Prevent aging and deterioration of rubber products

Rubber products on automobiles, such as tires, transmission belts and dust covers, often age, expand or deform, resulting in poor performance and short service life.

For example, the aging of rubber products is mainly due to the fact that rubber belongs to unsaturated high molecular hydrocarbons, which is easy to absorb oxygen in the air and oxidize. At the same time, vulcanized rubber has certain air permeability, and oxygen is easy to enter the interior for oxidation. In particular, direct sunlight can promote the rapid aging of rubber. After being contaminated by gasoline and engine oil, rubber products will cause volume expansion, gum looseness and elasticity decline.

In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.
