How to fix a car crash and how to fix a car crash

Here's how to fix the car if it's dented:

The first method is to heat it with hot water and flatten the recessed part yourself. Boil a large bucket of hot water first, then heat the hot water with a spoon to the recess.

After the plastic is heated to a certain extent, push it out on the back of the concave surface by hand until the concave part is convex and recovers. If it is hard to the touch and still can't come out, it proves that the heating is not in place, and a large amount of hot water is needed to continue heating.

The second method: buy a dent repair kit online. Clean the recessed part first, then put a few things that resemble toilet suction cups in the grooves, insert a suction rod into these suction cups, and pull the suction rod firmly.

The principle of this method is that after the suction cup touches the metal plate of the groove, the inside is in a vacuum state, and a huge pressure difference between the inside and outside will occur. At this time, if you pull hard, the metal plate groove will be sucked out.

This method requires enough strength and the ability to find the power point to have a good effect.

If it is slightly dented, the material area has not changed, which can be slowly corrected with a spacer and a suitable sheet metal hammer. If it is deep and the material is stretched, the area that is larger than before the deformation can be roughly flattened with a sheet metal hammer and spacer, and then repaired with filler.

First clean the hollow part, then put the special glue into the glue gun, plug it in, and preheat it for about 7 minutes. Then, choose the appropriate spacer, taking care to use a large spacer for large depressions. The larger the spacer, the greater the traction.

Then use an applicator to evenly coat the sol on the gasket, quickly stick to the depression, and press gently until the special glue is fixed and loosened. Align the hole in the middle of the towing bridge with the fixing shim, place the nut on the gasket screw and tighten it, then turn the nut until it is pulled out until the depression is flat. Once the repair is complete, the tool is removed, then alcohol is sprayed on the remaining rubber from the body, and finally cleaned with a spatula.

However, not all dents can be repaired. As long as the paint does not fall off, the paint does not fall off, and the depth of the dent is not very deep, then the dent is relatively easy to deal with. If the depression is located near the wheel eyebrow, corner, or AB pillar, the difficulty of repair will be greatly increased.

Some of the metal covers on the body of the car were dented by the collision, and the only way to do it was to repair the sheet metal. Sheet metal repair needs to be handed over to professionals, and car owners cannot carry out sheet metal repair themselves.

Sheet metal repair is more troublesome, and it needs to be repainted after the sheet metal repair is carried out. Sheet metal repair requires some tools to pull out the depression, and after the repair is completed, the surface of the metal is not flat, so it cannot be painted directly.

After the sheet metal repair is completed, putty needs to be scraped before it is sanded. If the putty is too thick, then the putty will crack after a period of time, and if the putty cracks, it will affect the rust of the body. After the putty is sanded, it can be painted.

If you want to implement sheet metal repair, it is recommended to go to a professional sheet metal repair agency.

The effect of the repair of unprofessional sheet metal repair institutions is not good, and the materials used are very poor, and color difference may occur. It is normal to have some scratches during the use of the car, and if it is only a minor damage to the paint, then there is no need to repair it. (Photo by photo:.)

If the door is hit and dented, you can prepare hot water to repair it yourself, or drive it to the garage for non-marking repair or sheet metal repair.

1. The owner can prepare hot water, pour it on the recessed position of the door, and then use a hair dryer to bake the recessed position of the door, and the recessed position will automatically rebound.

2. You can also remove the inner door panel of the door, pour hot water on the recessed position, and then try to press outward on the inside of the door by hand, or use an object with a larger area to eject the recess position.

3. If the owner's hands-on ability is not strong, try to drive the vehicle to the car repair factory, and the staff will use professional tools to eject the depression position, and if necessary, it is necessary to use sheet metal repair to repair the depression position of the door.

4. Traceless repair: traceless repair can also be called micro sheet metal, as the name suggests, there is no need to destroy the original car paint, and the part of the paint depression is repaired, which is characterized by the fact that the process of repair is simple and short, and it is recommended to use this method when encountering a small area of depression, but you must choose a regular store technology to be guaranteed.

5. Sheet metal repair: apply putty in the sunken place and then grind it flat, and then re-paint it at the repaired part, this repair method wants to be more mature and is widely used in the market, but the process is more troublesome, and after a long time, it can be seen a little different from the original paint in the repair place, and it is more expensive.

Repair methods for the car to hit the dent: 1. If it is only a slight depression and the material area has not changed, it can be slowly corrected by using a horn and a suitable sheet metal hammer; 2. If it is deep and the material is stretched, the area is larger than the area before deformation, and the sheet metal hammer and horn can be roughly knocked flat first, and then repaired with filler.

I believe many people have heard of using hot water to repair car dents, this method is indeed credible and feasible, but this method has great limitations, if you encounter iron or aluminum car dents, this method will not work. For the repair of metal material deformation, boiling water is obviously not feasible, according to the degree of deformation to choose different repair methods, such as automobile sheet metal shaping machine, if the body paint has cracks, paint peeling, this method is not feasible.

We can also buy such a set of dent repair tools online, which is not expensive, and you can have it for dozens of dollars. First of all, clean the indented area, then load the special glue into the glue gun, plug in the power supply and preheat it for about 7 minutes. Then choose the appropriate gasket, pay attention to the large depression with a large gasket, the larger the gasket, the greater the traction force, and then use the glue gun to evenly coat the gasket with sol, quickly paste into the concave position, and gently press until the special glue is fixed and then let go.

Align the hole in the middle of the towing bridge with the gasket after attaching, put the nut into the gasket screw bar and tighten it, and then twist the nut until it is pulled to the recess and trimmed.
