First, how to repair the scratches yourself?
1. Repair of minor injuries: If any injuries are found on the car body, check the extent of the injuries first. If it is only a shallow scratch on the surface paint, clean up the place to be cleaned without dust, and wax it when it is dry. According to the situation, it can also be treated with mixture. The wiping method is linear wiping. After the scar disappears, wipe it with a finer mixture and then wax it.
2. Repair of scratches and paint removal: For deep scars, the key point is to observe whether the metal surface is bare. If the metal surface is invisible, it won't rust. Wipe the paint surface clean without dust before spraying. When it's dry, you can concentrate on applying decorative paint. Spray it up bit by bit with a pen tip, or evenly at intervals of about 30 cm, and then wait until the paint is completely dry.
3. Repair of deep wounds: Deep but slender wounds can be well repaired with colored putty. Sandpaper the wound. Don't enlarge the wound casually. It is important to clean up the dirt. Putty should be carefully daubed to make it completely enter the interior. Finally, the mixture is coated and waxed, and the work is finished.
4. Repair of dents: The treatment of dents is one of the most troublesome tasks in car body maintenance, and it is very important to lay a good foundation. This step is not done well, no matter how good the painting is, the effect is also poor. When painting, don't forget to cover the surroundings with newspaper, so that the paint won't spread around. I suggest simply spraying paint and then sticking a reflective sticker (provided that the sticker can completely cover the scratched surface). If you feel bad, let the repair shop let professionals handle it. The usual procedure is: shaping-plastering-leveling-painting-and then spraying bright paint.
Second, it is the most scientific and reasonable way to deal with the car collision in various situations. What we want is to save trouble, labor and money, right?
1. What should I do if someone scratches your car and runs away or accidentally scratches it while driving? If someone scratches your car and runs away, you should call the insurance company and say that you backed it up. If there is no risk of car scratches, I will talk about how to repair it myself later. What needs to be added is that if there is car body scratch insurance, all scratches should be reported to the insurance company before the auto insurance expires and saved together in one step.
2. What if there are scratches on the expressway? Under the condition of ensuring safety (don't brake suddenly to protect the scene, which is uneconomical and dangerous), park the car in the emergency parking area at the first time, place a triangle at the distance of 150 meters, and then negotiate with the other party for compensation. Call the police if the negotiation is improper. The police will judge who wiped who according to the contact position of the car. If he doesn't stop, don't stop, speed up chasing him, call the police when he sees the license plate, and say that the other party has hit and run. When the police stopped him at the exit, he said nothing.
