Car paint cannot be recycled too much polishing will destroy the car

My car has been in the car for 4 years, and there are no other problems, but the'face' looks a bit older. Currently, I have no plans to change the car, so I will give it a beauty first. "Mr. Liu is polishing his Jetta, intending to restore his car's brilliance through plastic surgery. Scrub on the car body carWhen driving, there will always be such and other problems on the paint of the car. There may be small defects on the surface of the paint film such as coarse particles, sandpaper marks, flow marks, whitening, orange peel, etc. In order to make up for these defects, some auto beauty shops will It is recommended to polish your car paint to improve the mirror effect of the paint film and achieve the requirements of brightness, smoothness and beauty. Such car paint care is called mirror care, commonly known as polishing. Nowadays, the car paint surface is mainly transparent paint, and its craftsmanship is more exquisite. The care procedure is similar to ordinary paint: the first is grinding, which is to remove the original defects of the car paint. It is mainly used to remove oxidation, hairline scratches, etc. Varying degrees of paint damage such as micro-scratches. According to different damage and the nature of the paint (clear paint or ordinary paint) to choose the type of abrasive. The polishing agent is mainly divided into light-colored polishing agent and dark-colored polishing agent. As the name implies, it is a dark-colored polishing agent for dark-colored cars, and a light-colored polishing agent for light-colored cars.Another function of polishing agent is to act as a strong force before waxingdetergentOr called "detergent". After you "wash your face" on your car, you need to apply a layer of reducing agent, also called "sealant". Its function is to restore the original face of the car paint. Polishing look at the steps Firstly, use a paint cleaner with strong detergency to clean the whole car to avoid particle dust from causing new scratches during grinding; secondly, for defects such as coarse particles, fine sandpaper marks and flow marks on the painted surface, use it before polishing Dip 600# to 1000# water sandpaper into a small rubber lining block, and lightly polish it until it is smooth, taking care not to wear through the paint layer; then use a machine grinder to add coarse grinding paste to the traces of the water sandpaper Coarse grinding, adding grinding paste for polishing and fine grinding; using machinerypolisherAdd the mirror treatment agent to throw away the marks left by the rough grinding paste to achieve the effect of mirror polishing of the paint film; after the grinding and polishing, wipe off the grinding and polishing paste, and immediately wipe all the polished parts with cotton yarn dipped in varnish wax , Then wipe off the excess wax with dry cotton yarn to make the lacquer bright like a mirror and dazzling. To check whether the paint treatment is successful, you can take a newspaper and place it on the surface of the paint. If you can read the newspaper from the reflection of the paint, it means that the transparent paint of this car has a deep shadow and the surface is smooth as a mirror. At the same time, you can also use a small method to test whether your car has achieved the perfect effect through the above-mentioned steps. You can rub the car body with the transparent paper on the outer packaging of the cigarette box. If it feels uneven, it means that the oxide layer is not Removed, the use of abrasives is simplified in the middle, but sandpaper is used instead of smoothing the scratches. Do not do more polishing However, after all, unlike human skin, which can be regenerated, car paint cannot be regenerated. After being polished once or twice, the car paint layer, which is not thick, will become thinner and weaker. Eventually lead to irreversible aging. Therefore, unless it is a last resort, polishing should not be done or done as little as possible, and after one polishing, careful maintenance is required.
