The car is an outdoor means of transportation, which has long been eroded by moisture, oxygen, carbon dioxide and other media in the atmosphere. Over time, the surface of the body will be oxidized and corroded. The paint on the surface of the car is its "coat", which can avoid the chemical reaction between the surface of the body and the surrounding medium, delay the phenomenon of car destruction, and prevent the car from rusting.
Car paint for the protection of the body frame has a very important role, the general paint is scratched, novice drivers will quickly send the car to the repair shop for repair, so as not to be scratched part of the erosion of water vapor, resulting in body rust, affecting driving safety. However, in life, there are also many car body surfaces that are scratched out of chaos, but the owner has not repaired, why is this?
Mr. Wang bought a Volkswagen Bora and has been driving it for three years. There were many scratches on the surface of his car, and some of the scratches were very obvious, but Mr. Wang did not send the car to be painted. When going to maintain the car, the clerk suggested that Mr. Wang paint the vehicle, but Mr. Wang refused on the spot.
Mr. Wang said that when he first bought the car, his skills were not skilled, and when he reversed into the warehouse, he bumped into the pillar next to him, and the door was scratched. He was also very distressed when he saw it, and on the 2nd day he sent the car to be painted. However, just two days after making up, the car was scraped again, and the body was scraped one after another, and I got used to it. He felt that as long as the primer was not revealed, this scratch did not matter.
The cost of repainting paint is not cheap, and the paint of the new car is about 300 to 500 yuan. Even if the scratch is small, but it just spans two sides, the other party will calculate the price of the two faces. And when repairing paint, it is also necessary to set the price according to the difficulty of repairing each side and the materials used, if the angle of the bump is too tricky, the cost of paint repair is more expensive.
After spending a few times of "unjust money", everyone has a long memory, and few people see scratches on the body and go to paint it. After listening to Mr. Wang's words, the maintenance worker also said that the current owner has become smarter, and everyone knows that these scratches will not affect the safety performance of the vehicle, nor will they affect their own car, so there are fewer people who come to the store to repair the paint.
Generally, the paint repair in the store is basically bumpy and more serious, not only scratched the top paint, but also the primer has been scraped off. The traditional car paint is generally divided into four layers, and the phosphating layer and the capacitor layer will be directly attached to the body, which has an anti-corrosion protection effect on the car paint. The medium primer layer adheres to the electrophoretic layer, which protects against ultraviolet rays, protects the electrophoretic layer, and strengthens the corrosion protection of the body.
Electrophoretic layer, primer layer is the most important car paint to protect the body, if the two of them are damaged, the body structure will be directly exposed to the air, for a long time without repair, the water vapor in the air will adhere to the body frame, and the iron in it will chemically react, and the body will begin to rust.
Body rust will not only affect the beauty of the vehicle, affect the value of the vehicle, but also produce safety hazards. If the body is corroded by 1%, its strength will drop by 5% to 10%, and when it encounters a traffic accident, the ability to resist risks will decrease.
Old drivers know that the role of car paint on the body is very important, small bumps they will not care, but in the end the paint is exposed, they will not continue to let it go, will send the car to the store in time to repair the paint. If only the topcoat is scratched, as long as the area is not large, there is no need to care too much.
