How to fix a dent in a car door yourself. We remove small dents on the car ourselves

12.06.2019

During the operation of the car, scratches, chips and dents appear on the body. The reason for their appearance can be both negative factors environment and careless driving. Chips and scratches are painted over. Repair and pulling dents on the car is carried out using various methods and devices to eliminate metal jams.

Before you straighten a dent on a car with your own hands, you need to know what types of damage exist. Dents on a car come in a variety of shapes and degrees of damage. Small defects, as a rule, appear on the roof and hood of the car due to hail, and small stones. Medium and large metal creases are a direct result of careless driving. Such dents on the car body can have a complex shape.

If the paint at the site of a large crease was covered with cracks and began to fall off, then, in addition to eliminating the dent, it will be necessary to restore the paintwork. Otherwise, on the part of the body where the damage has occurred, pockets of corrosion are formed.

Ways to remove simple dents on a car

Repair small dents, performs without repainting the damaged area. The defect is corrected using PDR technologies(paintless dent repair), that is, without repainting the part to be restored. To perform the work used:

Magnets. Allow to align minor damage body. a small piece of lint-free cloth is placed under the fixture.
Glue applicator, the device is attached to the car body with glue. After the adhesive has dried, the specialist slightly pulls the applicator in his direction, thereby leveling the body crease.
Suction cups allow you to correct simple defects. The vacuum pulling method removes metal creases formed after small stones, hail and icicles fall into the machine.
A building hair dryer, with the help of a tool, eliminates defects that have a different shape. warm air they blow over the damage, after that, immediately douse it with cold air from a can.
Hooks. These tools are useful for pulling hidden details. They get boxes, and stampings from hidden areas of the body surface.
Fender. It has a cigar-shaped shape, and is designed to flatten outwardly arched metal.
Rubber mallet. WITH reverse side of the damaged area, a rubber backing is installed. With gentle strokes level the surface. The method of removing dents on a car is applicable for both small and deep defects.

Also to the list necessary tools refer to the Pops a Dent defect alignment kit. It includes nozzles, plastic bracket, glue. Repair is carried out as follows:

The center of the damaged area is carefully degreased.
Heat up the adhesive. To do this, the glue stick is inserted into the gun, and connected to the mains.
The heated composition is applied to a rubber nozzle, in a circular motion glue it to the center of the damage.
After 2-3 minutes, a bracket is attached to the overlay.
The lamb bracket is screwed onto the nozzle until the defect is eliminated.
5 minutes after completion of work, the device is removed from the body.

Usage special equipment Pops a Dent is useful for frequent dents on the car body. If the defects of this plan appear rarely, it will be more profitable to use other technologies for pulling damage.

How to fix a severe dent with your own hands

To eliminate the deepest dent, impact pads of various shapes and hammers are used. Spoons are used as a forged tool. They have a different shape and size, depending on the type of damage.

In the center of the damage, the metal is thinner than at the edges. Before straightening, it is necessary to pull the iron to the center of the defect. To do this, use a gas burner. Next, perform the alignment of the dents.

After rough alignment of the defect, it is covered with putty.

Repairing dents with a jack

Pull out the dent of the car body with your own hands, a jack will help. The device is used to eliminate deep damage on the wings of the car.

Before carrying out work, dismantle the front turn signal and headlight. From the side of the dent, the jack rests on the heel (a rubber bar is preliminarily placed under it), the lever of the device must rest against the opposite edge of the opening. The operation is stopped after straightening the defect, and the damaged area is covered with putty.

Removing dents on a car with a reverse hammer

Straightening dents with a reverse hammer is performed when the driver has difficulty accessing the damage site, or the repaired parts cannot be dismantled. This type of body dent repair usually requires subsequent painting of the repaired part. To straighten a dent, follow these steps:

Clean, dry and degrease the surface to be restored. Remove traces of corrosion.
One end of the reverse hammer is attached to the center of the damage. Perform the operation using a special suction cup or applicator.
Editing is carried out by gradually increasing blows of the weight on the hammer handle.
After the restoration of the outer side of the body is completed, the hammer is disconnected.

The applicator or suction cup is only effective in straightening the body if the damage is not serious. In the presence of deep and complex defects, the hammer is welded to the surface, or they cling to technological holes using special hooks.

Straightening

The process that allows you to remove a dent on a car and repair a local area of \u200b\u200bthe body is called straightening. Work, with a certain experience and time, is carried out with their own hands according to the following algorithm:

Wash and dry work surface.
Degrease the damage.
Carry out body repairs.

Straightening of small damages can be carried out without subsequent staining of the damaged area. With the help of reverse hammers, hooks, a building hair dryer, suction cups and applicators, rubber hammers, the defect is eliminated.

If you need to fix a deep dent on a car, accompanied by creases, peeling paintwork and metal rupture, then use the following tool:

Hammer and anvils various forms and sizes.
Spoons.
Jack.
File.
Welding machine.
grinding device.

The anvils are applied to the outside of the dent, and from the center, with gentle strokes, a rough leveling of the surface is carried out. Spoons act as a substrate for a percussion instrument, but they are used to eliminate defects that have appeared in hard-to-reach places. After alignment, inspect the repaired area. If there are breaks in the metal, they are welded together. Remove excess bulges with a file. Next, you need to putty the body to level the working surface. The treated area is sanded, primed, painted and polished.

Correct putty

Before you putty the car body with your own hands, you need to prepare. This will help to avoid visible defects after painting the car:

Sand and remove excess metal bulges.
Degrease and clean the treated surface. In some cases, the operation is performed several times.
Repair the corrected area of damage by applying putty evenly in several layers.
After it dries, the surface is polished. It is important to ensure that the puttied layer is on the same level with the rest of the surface of the car body.
Apply primer in two layers.
Paint the surface with a spray gun. Lacquer is applied and the surface is polished.

Replacement of a part or part of it

If there are more serious damage, repairing dents will not help restore the integrity of the part. In this case, the body element, or its most severely damaged part, is replaced with a new one. When replacing, it is necessary to find a part identical to the one being replaced. If a specific area is being replaced, then the patch is cut out of the same metal. Then it is welded to the restored part.

Minor damage to the body, chips, scratches and dents on the car can be repaired without repainting. Previously undamaged parts of the hull are subject to restoration. If the paint cracks, breaks and kinks appear, it will not work to repair without painting.

A dent in a door is not uncommon. Either the spiteful critics will kick you out of anger, or you won’t see it yourself, or the other driver will “drift”. Unpleasant, of course, but there is no big trouble in this.

It's not about serious accidents when it is no longer up to dents, but about everyday mild cases in which inattentive drivers themselves are to blame or damage is the result of external mechanical impact. As for scratches, there should not be any difficulties at all. With serious defects, of course, it is better to go to a specialist who has both experience and a special tool. It is unlikely that a large dent can be completely straightened out on its own, with daylight flaws will be visible. But with minor damage, you can easily deal with it on your own. If you can get a repair manual for your car, a lot will become clear. Many are described in detail and step by step. repair processes. Such a book, by the way, can also come in handy during a trip, when non-standard situations happen, and there is no car service nearby.

First way

First you need to get the right tool. You will need a wooden block measuring 200x100 mm, a hammer and a rubber mallet. We take off the cover. Dismantling the glass will also not be superfluous. Apply a block in the area of the dent with inside doors, and with blows of a hammer, try to straighten the dent, which must be finally removed with a rubber hammer (mallet). The main thing here is not to overdo it, otherwise the metal may bend in the other direction. Having achieved a flat surface, the damage site should be primed, sanded, then polished and painted with a spray gun or spray can. After a couple of days, when the paint is completely dry, you can put the skin in place.

Second way

Sometimes a dent can be straightened without the help of a tool. It is enough to press on it with the palm of your hand from the inside. To do this, you will also have to dismantle the casing. Some craftsmen fix the defect with car camera, pushing it between the outer sheet and the structural elements of the door. The chamber is then pumped up. There comes a point when the pressure in the chamber becomes sufficient for the dent to snap into place. It remains only to tweak it a little. Further actions are the same as in the previous method: from priming to painting.

Third way

Can be armed modern technologies that are simple and efficient. For this method, you will need a can of liquid carbon dioxide and building hair dryer. Heat the surface of the dent with a hair dryer. When the metal warms up well, they take a can and begin to spray carbon dioxide on the damaged area. The metal, cooling, shrinks, the dent straightens. Light strokes will remain, and the job is done. Next - priming, sanding, painting.

Fourth way

This method differs from the previous ones in that you do not need to disassemble the door. The only condition for repair is access to the outer surface of the door, and, as you know, there is always access. To pull out the dent, various equipment is used, for example, an applicator, which is glued to the damaged area, and a mini-lifter, with which, after the glue has dried, the dent is gently pulled out. The same work can be done if you first acquire a suction cup or a magnet, which is applied through a cloth (rag). If the blow to the door was a direct one, and there are no scratches, the paint, in most cases, is not damaged. It remains only to pull the dent and continue to ride on.

If at mechanical action there was not only a dent on the door, but also its frame was deformed, it is unlikely that you will be able to cope with this problem on your own. Only a specialist will be able to determine the extent of the problem and how to fix it. If the door is not repairable, you will have to buy a new one, install and rearrange the entire old stuffing. But it is better not to bring it to this, carefully monitor the situation on the road, do not rush and do not fuss. Then save your nerves and time.

The most frequent accidents are minor accidents, while as a result of a weak impact on various body parts The car has minor damage in the form of dents and scratches. This article discusses how to remove a dent on a car door with your own hands.

General Features

If during an accident there was a direct impact without slipping, which resulted in a dent without a scratch, this greatly simplifies the restoration technology, since in this case it is not necessary to paint the damaged part or its fragment. It is possible to straighten a defect on a car door without painting different ways. Therefore, in order to remove these defects, different tools and materials are used. To better understand how to fix a dent on any part of a car, you should find a video that discusses the repair technologies described below.

One of the features of working with the door is that when repairing it, it is relatively easy to provide access to the dent from the inside of the part. To do this, remove the door panel, then full access to the inner surface will open, and the defect can be corrected by tapping or pressing without using a lever. In addition, if necessary, you can remove the dent on the removed door.

Straightening from within

This technology is one of those that allow you to even out dents without painting on body elements auto. It is based on differential pressure. Leverage is used as a tool. To correct the defect in this way, you need to insert the lever into technological hole body. When removing dents on the door, you can use a glass gap as such an opening: in this case, the lever must be long enough to reach the defect. The defect is removed by easy pressure on him.

Be careful and control the peaking so as not to bend the metal of the car door in the opposite direction. If this happens, such a defect can be corrected with a fluoroplastic chipper. Removal of a dent occurs with a click.

External alignment

It is possible to repair in this way all dented parts that are accessible from the outside, including doors. There are several options for removing defects using this technology. One of them is carried out using glue and special equipment, represented by an applicator and a mini-lifter. Repair begins with the fact that the applicator is glued to the damaged area. After the glue has completely dried, you need to pull out the central point of the dent with a mini-lifter, and at the end of the work, you need to remove the remaining glue from the car body.

Following the same principle of straightening dents from the outside of the part, you can pull out the defect with a piston or similar non-specialized devices, such as suction cups. As in the first case, the surface of the dent must be sealed with glue and a suction cup must be fixed on it. Repair of the defect is carried out by stretching after the adhesive has completely dried.

Another way to remove dents from the outside, also based on pulling them out, is to use a magnet. Repair consists in moving it over the area of the defect from its center to the edges with pulling on itself.

Place a cloth under the magnet to prevent damage to the paintwork. It should be borne in mind that only a small dent can be fixed with this method.

The following method of external straightening of dents differs in principle from those considered, it is based on a temperature difference. Such repairs are carried out using a hair dryer and a can of compressed air. Moreover, in order to close the dent in this way, you will need a powerful building hair dryer capable of creating a temperature of 300-650 ° C. Repair begins with heating the surface of the defect, then immediately blow it with a can of compressed air. A big difference temperatures (more than 350 °C) leads to straightening of the dent. Depending on the size of the defect, it may be necessary to carry out this operation at several points.

If after these works there are traces of a dent, they can be removed by tapping with a mallet. In this case, the damaged area should be covered with a soft rubberized material to avoid damage to the paintwork of the car.

Percussion

You can straighten and completely remove a medium-sized dent by tapping with a rubber mallet on the back. However, for this you need to have access to the place of damage. In the case of a door, you will have to remove the door panel to do this. Usually, repairs using this technology are carried out with mallets of various sizes, and hooks are used to close up areas that are not accessible from the inside. However, in this case, traces will remain from them, which distinguishes this method V the worst side from others discussed in this article. Read on for more information on how to straighten a dent.

Pops a Dent

This name is given to the device, which is a plastic bracket with rubber tips and nozzles. Also included with these devices are a glue stick and a gun.

Repair begins with degreasing the dent area, then you need to apply glue to the rubber nozzle. To do this, insert the glue stick into the gun and connect it to the network for heating. After that, the glue is squeezed out of the gun nose onto the working surface of the rubber nozzle and glued in a circular motion to the center of the defect. Excess glue protrudes through the holes on the nozzle, and its drying time is 2-3 minutes. Next, a bracket is installed on the nozzle through the hole and screwed with a lamb onto the nozzle, and the dent is pulled out. Upon completion of the straightening, the nozzle is left on the auto parts for 5 minutes.

That is, the removal of dents after hitting a car door using this technology, as well as some of those discussed above, is based on their extension. In principle, it is similar to straightening with an applicator with a mini-lifter, however, in this case use more sophisticated equipment.

Unfortunately, all elements of the external structure vehicle are not very durable, and therefore the question of how to fix a dent on a car door is quite relevant.

Most motorists prefer to take their car in for repair and trust the restoration of external coatings to specialists. However, all the work on straightening can be done at home. This will require special equipment, the skill of working with it, as well as a suitable room.

Exhaust dent on Mazda car door

Repairing damage to a car door with your own hands is attractive because you do not have to wait several days for it to be repaired in a workshop, and also because you will spend a much smaller amount on such repairs. Most drivers, faced with the problem of a dent on the front or tailgate car, they want to fix them so that after that painting is not required. This desire is absolutely justified, because painting will take additional time, materials and means, and it is unlikely that it will be possible to choose the color that the car was painted in before.

However, it is worth considering the fact that straightening the door without subsequent painting is possible only in cases where the dent does not have strong chips and the paintwork remains intact.

Suction cup - a tool for extracting dents on the body

Do-it-yourself door repair by heat treatment is one of the most popular, and it is not surprising, because all the units necessary for it are inexpensive and can be purchased without any problems. So, all you need for repairs is a powerful hair dryer and a can of compressed air. When choosing a hair dryer, it should be borne in mind that it will have to have enough power to heat the problem area of the door to the required temperature. Therefore, it is best to give preference to industrial thermal guns.

Thermal option for removing stains on cars

So, in order to properly repair a dent on a car door with your own hands using the heat treatment method, you must proceed according to the following scheme:

The essence of this method is that under the influence of a sharp change in temperature, the damaged metal will begin to smooth out by itself. However, it is far from certain that the dent will disappear after the first cooling. If this does not happen, the door will need to be heated and cooled again.

The procedure must be repeated until complete elimination damage (the number of repetitions, as a rule, depends on the size and complexity of the defect, as well as on the correctness of the work).

Removing dents on the door with suction cups

Set for straightening with suction cups

Sometimes to make repairs car door without painting with your own hands, vacuum suction cups are used. They are quite effective and completely safe for the paintwork of the part, but they may not always be used. The suction cup can pull out a shallow, even rounded dent, provided that it is not chipped. In this case, ideally, the shape and size of the suction cup and the dent should approximately match. You can fix a flaw on a car door without painting with the help of the following algorithm:

It is quite common to repair a dent on doors without painting using several vacuum suction cups. It is relevant when the damage has an irregular shape.

If your car door has minor puncture damage and you do not want to remove the door or its interior trim, you can remove them using hooks and levers. A set of these tools can be purchased at any specialized store. As a rule, a standard kit includes two to three dozen such tools. With their help, you can remove small defects without painting with your own hands at almost any point in the skin of the vehicle body.

Using hooks and levers to remove dents

This must be done according to the following scheme:

Designate all dents to be fixed and start working with the simplest and most affordable.
Pick up right tool(This should be given maximum attention, because otherwise you will not be able to remove the dent for a very long time).
Insert the hook into the most convenient technical hole in the door and “feel” for a dent with it.
Gradually increasing the force, push the dent in the desired direction and squeeze it out. In this case, you can attach some hard object to the outside of the dent so that in case of excessive force the metal is not bent in the opposite direction.
After the repair of one do-it-yourself dent without painting is completed, you can begin to eliminate the next one.

If you do not have enough experience with this kind of tools, then before removing a dent on a car door, you can practice on already unused and unnecessary parts.
