Repair dents by yourself. Facing small dents, it is more expensive to find a specialized technician. Because of the different skills and proficiency, you only need to repair the dent yourself. The following dents are self-repairing.
Self-pit repair 1 pit repair is an automobile pit repair technology without destroying the original paint. It is said that there are two forms of treatment:
One is manual processing. It is said that after disassembly, the pit was pried out with a special hook, then knocked back with a rubber hammer and leveled with light. This treatment has basically no damage to the paint surface, but the edges and ribs cannot be treated, and more masters are unwilling to show them to the owners during construction;
One is the processing of the machine. It is said that the concave part was sucked out by the machine and then knocked back with a rubber hammer. The tendon part can basically be repaired and operated in front of the owner.
If the depression cannot be repaired, the problem can only be solved by sheet metal painting.
If you do it yourself, it will be very simple. Find a mop and make a simple tool.
Removing the door trim panel is very simple. I don't know how to remove it. You can search your model online. Then take off the horn, stick it in this hole and pry open the dent in the car door. Touch the position by hand first, and it is best to circle it with a marker. Don't pry it in the wrong position.
Then just use a touch-up pen to trace it. Don't draw too much at a time, draw as many times as a thrush, and you will hardly see it when you are far away.
This method is suitable for doors, front and rear fenders and other places where sticks can be inserted behind. If the stick can't reach the opposite side of the pit, it needs to be pulled out from the outside. At this time, you need to use hot melt adhesive. Stick the beverage bottle on the pit with hot melt adhesive, and then pull it out by force.
The above methods are used by people who are "too poor to open the pot". It would be much easier if we could spend a little more than ten dollars. There are special tools for repairing dents on the Internet.
Open the hot melt glue gun for about 5 minutes, and the hot glue will flow out. Then, choose a sucker with an appropriate size, apply hot glue on it, and immediately stick the sucker in the concave part, usually in the middle of the concave part. Hurry up, or the glue will solidify when it gets cold.
Then install the pulled support frame, screw on the hexagon nut and tighten it bit by bit. A watched pot never boils. You must be slow and steady.
Finally, when you twist it, the effect will gradually appear and the sunken part will be gradually pulled out. Then you will hear a bang, and the sunken part will suddenly pop up.
After the pit bounced back, there were still bumps around it. The above operation can be repeated with a small suction cup until it is basically flat. Blow it with a hair dryer after pulling. When the glue gets hot, the sucker can be easily pulled out of the car.
Look at the final effect, although there are some small pits, but it is not obvious. The effect is that scraping putty and painting can't be compared. After all, it doesn't cost much From my own point of view, I can't even pull up such a pit. A car is just a means of transportation. This pit has no effect on the function of the car. Why do you care?
The above tools can only be used in areas with small depressions. For deeper depressions, another hammer is needed. This kind of tool is often seen in repair shops and can be bought online for only tens of yuan. The small sucker is also fixed in the concave position with hot melt adhesive, and then the impact hammer is used to hook the tail of the sucker and pull it out, which is more powerful and suitable for repairing the big pit.
For the front and rear bumper pits, because they are plastic and have certain toughness, you can use a hair dryer to blow hot air, which will naturally rebound. Or like when I was a child, table tennis was flat and would swell up if I put it in hot water. You can also pour a pot of boiling water on the bumper.

The small dent 1 cm of the car can be repaired by lever principle, and if there is touch-up paint, it can be repaired by paint remover.
Touch-up pen is a tool for repairing car scratches. You can choose the corresponding model according to the color of car paint. When the car has tiny scratches or paint falls off, it can be made up with a touch-up pen in time. Some models are special, so you can only use special touch-up pens. Touch-up pens are divided into topcoat and car paint. The topcoats are common paint, metallic paint and pearlescent paint. The brighter the paint color, the more expensive the complementary color pen, so the complementary color pen for white vehicles is the cheapest. Antioxidants and stabilizers are usually added in the manufacturing process of touch-up paint pens, so that touch-up paint pens have good stability and achieve the same effect as car paint.
When the car body is sunken due to extrusion or collision, it usually needs to be repaired by sheet metal, such as lacing, shaping, grinding, putty coating, grinding, particle glue spraying and painting. After a set of sheet metal repair process, the general quick repair chain store can basically solve it for two or three hundred yuan.

The sag repair tool is relatively simple to operate, basically it will be operated when you get it, and generally it will be accompanied by instructions.
Dent repair tools are similar in principle, and usually do not cause additional damage to car paint and body.
However, the dent repair tool is not omnipotent. It can only repair the undamaged dents on the car body surface (paint surface). Moreover, even the concave repair tool is useless for the concave on the car rib or the concave on the narrow uplift line (non-planar position), and the specific concave degree can be judged by yourself. If you can't handle it yourself, you can only go to 4S or the garage.
Self-trapping repair method for 3 slight depressions;
If the door is slightly dented, we can try to repair it ourselves. There are many car dent repair tool sets on the internet, and the price is not expensive. There is only a set of dozens of pieces, and the tools inside are basically complete, suction cups, hot melt glue gun.

How much does it cost to repair the depression?
In terms of price, automobile dent repair technology determines the price according to the difficulty and area of dent repair and the sharpness of dent. The sharper the dent, the more difficult it is to repair, and the price is more than several hundred yuan. For example, the price of an egg-shaped depression is generally around 150 yuan.
Another folk remedy is to heat the concave part with hot water. As long as it reaches a certain heat, the body material will become soft, and then it can be repaired by pushing it out from the internal test. Hot water heating is like a soldier's ball with a depression, and then it will slowly recover after adding hot water. However, this method is too rudimentary. If it is not a plastic body, the effect is not obvious.
To sum up, the repair of the car door depression has great limitations. If the depression is deep and still on the body line, it will be difficult to deal with, and the final effect is not good; If there are still cracks, you'd better brush the sheet metal again.
