Grinding and polishing materials: good experts in car maintenance
1. Shallow scratches Due to the friction in use and improper daily care, the paint surface of the car has been slightly scratched for a long time, and the primer is not exposed. This kind of scratch is obviously obvious in the sunlight. It can be removed by a professional polishing method.
2. The etch mark is a surface abrasion. Insects, bird droppings, sap, tar, and asphalt all have etch marks. Only a very small amount of abrasive polishing is available.
3, cracks If you do not make some necessary care for the paint surface, metal paint may produce a very fine crack, it will continue to infiltrate the paint until "breakdown" the entire paint layer, this phenomenon is called "turtle" crack". Sometimes cracks can occur due to problems with the quality of repainting. If there is car wax in the crack, you will find that the car body has a streak (scratch) crack. Regular waxing can reduce cracking.
5. Traffic "film"
The car generates a strong electrostatic layer due to friction during driving. Static electricity has a strong adsorption capacity for dust, oil and chemical dust, and it takes a long time to form a hard traffic film. It is easy to cause oxidative corrosion of the paint surface and can be polished and polished.
6, paint surface oxidation car under the sun's ultraviolet light, the paint film continuously evaporates oil into the air to protect itself. If the time is long, the oil on the lacquer will be dispersed. The brightness and depth of the paint surface are greatly reduced, so that the paint surface is gradually whitened to form an oxide layer, which shortens the life of the paint. It can be observed by the naked eye that the paint is black, white and dull. Severe oxidation can be treated by grinding and polishing.
Car buyers know that the parts and components of vehicles with different brands or different models are also good or bad, but if you don’t pay attention to maintenance, it’s futile to buy a good car, so car maintenance is very important, when driving the car. When the day, don't forget to give the car regular maintenance to achieve the repair effect. When encountering some difficult problems, don't blindly “do it yourself”, and go to the professional repair shop for maintenance, so as to avoid “good help”. (Source: Hantong Industrial)
