Be careful of the aging and fading of automobile paint

Car lacquer has little impact on the overall performance of the automobile, but it dominates the aesthetics of the car. Lacquer killer is ubiquitous at ordinary times, exhausts automobile exhaust and iron powder in air, natural oxidation of paint surface and so on.

it is now in the rainy season. After the rain, owners usually wash their cars in time. Bird droppings, gum and so on are the biggest enemies of car paints. People in the industry remind car owners: in the rainy season, we should pay special attention to acid rain, bird droppings, gum and iron powder corrosion to vehicle paints.

1. Oxidation of lacquer surface

under the ultraviolet radiation of the sun, the paint film continuously evaporates into the air to protect itself. The length of time will cause excessive loss of oil in the paint. The brightness and depth of the paint surface are greatly reduced, making the paint slowly whitening, forming oxide layer and shortening the service life of the paint. The naked eye can be seen in the naked eye, white and glossy. Oxidation can be seriously treated by grinding and polishing.

Two, traffic “ membrane ”

the car has a strong electrostatic layer due to friction in running. Static electricity has strong adsorption capacity for dust, oil and chemical dust, and it forms a hard traffic membrane for a long time. It is easy to oxidize the paint surface, and it can be treated by lapping and polishing.


If it is not necessary to make some necessary care for the paint, the metal paint may produce a very small crack, it will continuously permeate the car paint until “ break through the ” the whole paint layer, this phenomenon is called “ crack ”. Sometimes cracks occur because of the quality of heavy spray paint. If there is vehicle wax in the crack, the crazing phenomenon will appear in the body. Often wax can be less cracked and produced.

Four, discoloration

oil fumes and pollutants in the atmosphere are the main causes of fading and discoloration of automotive paints. When fading and oxidation are different, the color of car paints is uneven when fading occurs. Moderate and mild fading can be treated by grinding and polishing.

Five, erosion mark

The erosion marks are surface abrasion. Insects, bird droppings, sap, tar and bitumen are all likely to cause erosion marks. Only very slight can be used for grinding and polishing.

Six, shallow scratch

because of the improper use of friction and improper daily care, the paint scratches slightly and the primer is not exposed for a long time. Sunshine The lower size is obvious. General use of professional polishing method can be removed.

Seven, water mark

The line of water marks is ring-shaped. It is the traces left behind by the evaporation of water droplets, which is easier to stain with oxidized cars and commonly used washing machines. When water marks are slight, wax polishing can be cured; severe grinding or painting is needed.

after knowing the harm of paint, we must find a feasible way to maintain it. At present, most methods of painting are waxing, sealing and coating. But what's the difference between these? Then let's get to know.
