How to deal with scratches in cars yourself?
Slight scratches
First aid products: fine wax, coarse wax.
The slightly scratched paint damage area is on the topcoat surface and can be completely repaired by waxing. Treat with a mixture. The wiping method is to wipe it straight, and then apply wax. You can first use coarse wax, then apply fine wax, and in the same direction from the inside to the outside, so that almost all the fine scratches will be removed. Of course, there is another way to save money by repairing it with toothpaste, gently apply it to the shallow scratches, and then apply it counterclockwise with a soft cotton cloth. After a few times, it not only reduces the scratches, but also prevents the air from eroding the car paint injuries.
Scratches without primer
First aid products: fine wax, patchwork pen.
Slightly larger scratches can be used to help with the emergency. Repairing pens are sold in general car supplies stores. If the owner reports his or her car model and official color name, he or she can buy a suitable color patch pen. The price is generally around 40-50 yuan. Before use, shake the paint inside the patchwork pen and apply primer like nail polish. You can add a certain diluent to the patchwork pen so that it can be sprayed smoothly. Spray carefully to repair the locations that need to be repaired. After the patchwork pen is dry, then apply the fine wax.
Scratches of primer have been seen
First aid products: mark removal and anti-rust agent, self-spraying.
For severe scratches, if you can see the color of the lower primer, it depends on the scars. Generally, the bumper, rearview mirror and some cars' wheel arches are engineered plastic and will not rust. Whether to repair the paint depends on the owner's own requirements. But if these severe scars appear on other parts of the car body, they need to be repainted, otherwise even if it is a small damage, the steel plate will begin to rust. By then, even if it is a repair, it will be difficult to prevent rust. Car owners can first wash and dry the car, apply rust remover on the scratches, and wait for 10 to 15 minutes to wipe the rust remover on the surface of the scratches to avoid rust.
Scratch and depression treatment
First aid product: dent repair technology.
If the scratches and dents left after the collision of the car's surface do not fall off or paint, the perfect repair effect will be achieved through the dent repair technology. A recess restoration takes about 20-40 minutes, which greatly reduces the cost (about 50% of traditional sheet metal, spray paint) and will never deform and fade. The tools required for the dent repair are not complicated. The crowbar is mainly used to push the dent into the steel plate from the inside out to the outside. This method must be delicate. A little bit of fine adjustment is the key. Then use a rubber hammer to knock it from the outside to the inside to repair the overall shape. Finally, use a pointed thing like a pencil tip and then finely adjust it to highlight the convex marks on the car body.
bumper scar treatment method
First aid product: special chemical synthetic agent.
If the bumper is just slightly scratched, although it is not a big deal, it is full of scars and it is ugly. You must find a way to repair it. Car owners can use special chemical synthetic agents to repair the bumper, which is very simple to operate and can be repaired by anyone. The owner first cuts off the burrs on the bumper, preferably with a knife to smooth the whole body and apply putty on the potholes to smooth it. Prepare putty close to the color of the bumper. The putty is synthesized with the main ash agent and hardener and mix well. Apply the putty with a spatula. The trick is to embed the scar part. After 2-3 hours of the putty being solid, polish it with water sandpaper and spray paint after a week.
