How to remove small dents on a car. The Most Effective Do-It-Yourself Dent Removal Technique

Removing dents after hail- this is a completely solvable problem for every car owner whose car has been exposed to this atmospheric phenomenon. To do this, one of four methods of paintless body repair can be used. Each of them has its advantages and disadvantages, as well as the level of complexity of their implementation. In addition, they use different tools that should be available to the masters. Next, we will discuss these repair methods in detail.

Existing hail dent removal methods

The procedure for removing dents without painting is fundamentally different from body repair with the restoration of the LCP. Indeed, in the case of the latter, the car body undergoes partial disassembly, which requires a significant amount of time and effort. The process of removing dents takes place directly on the body without the need to dismantle its individual parts. Currently, experts use four main methods:

• lever;
• adhesive;
• vacuum;
• thermal.

All of them belong to the so-called PDR methods, that is, paintless dent removal methods (Paintless Dent Removal - English). Let's analyze each of them separately:

• Lever method- the most popular in the service station, since it involves the use of special levers. Repairs can sometimes be hampered by the fact that it is not possible to place the levers directly under the affected areas of the machine body. In addition, often, in order to get to the individual surfaces of the body, it is necessary to dismantle the elements of the interior trim or technological mechanisms.
• glue method carried out with the help of special tools that literally pull the indented surface back. To do this, special caps are glued to the damaged area, which are subsequently pulled up, and they, in turn, pull the surface of the body along with them.
• vacuum method. This method is similar to glue. Its only difference is that instead of glued caps, vacuum suction cups are used.
• thermal method removal of dents after hail without painting is based on a sharp heating of the damaged surface with its subsequent sharp cooling. As a result of this approach, the body is deformed and takes its original shape. Heat up usually building hair dryer, and cool compressed air.

Do not delay the repair after deformation of the surface of the case, since the metal tends to remember new form. Therefore, the more time passes, the more difficult it will be to correct the situation. In addition, there is a risk of deformation paintwork damage. If it is not restored, then there is a threat of corrosion.

Hooks for lever dent removal

This method is most common in service stations. It works best on large surfaces, away from stiffeners. To perform the procedure, special tools are used - long levers, one end of which acts pointwise on the dents from the inside.

If a dent has formed in a place where inside there is a stiffener, then there is an option when, with the help of a building hair dryer, the sealant on which the amplifier is fixed is heated, after which it is bent, giving access from the inside to the damaged surface. Further, the procedure is carried out in a similar way.

Often, after straightening dents, it is necessary to perform polishing paintwork. How to do this you can read in.

Currently, there are whole sets of levers for removing dents on sale. They can include from 10 to 40 (and sometimes more) different hooks and levers, with which you can remove most of the dents on the surface of the car body. However, in fairness, it should be noted that such kits will be of no use to a private car owner. After all, they cost a lot of money, and you will have to use them, to put it mildly, rarely. Therefore, they are more suitable for professional service stations.

However, if you still have such levers, then you can try to perform the repair procedure yourself. The process depends on the specific situation and the degree of damage, however, on average, the following algorithm is applied:

Before you perform the described procedures yourself, it will be useful for you to practice on some old body parts. The process is simple, but requires some skill.

Removing dents from hail using adhesive and vacuum methods

It should immediately be noted that these methods can only be used if when the integrity of the paintwork is not violated at the place of deformation. If there are chips or scratches, then you need to get rid of them. How to do this, you can read on our website. The fact is that the tools described below have a strong mechanical impact on the surface, which can lead to delamination of the paintwork.

To remove dents from hail with your own hands using the adhesive method, you need the following tools:

Dent removal kit

• minilifter (it is also called a reverse hammer);
• glue fungi (caps) of various diameters;
• glue;
• adhesive thermal gun;
• liquid to remove adhesive residue;
• hammer;
• teflon core with a blunt tip.

Professional minilifters designed to lift dents up to 2 cm in diameter are expensive. However, today on the market there are simpler and cheaper designs, which are a clamp with suction cups, which can functionally be used instead of minilifters. The price of such devices is much lower. An example of this is the Dent Remover kit.

Paintless dent repair technology

One of the PDR technologies is the use of "fungi". By gluing small suction cups with a hard center but soft edges, the dent can be quickly pulled out without painting. The master will show and tell with a visual demonstration

Hail Dent Removal adhesive method performed according to the following algorithm:

1. First, the body must be washed and the damaged area degreased. This can be done using various means - alcohol or white spirit ( do not use solvents for degreasing, as they may damage the paintwork).
2. Glue is applied to the piston of the required diameter, after which it is installed in the center of the recess on the body. Leave for about 10 minutes to allow the glue to dry.
3. After that, you need to take a minilifter or clamp and place the other edge of the piston in its groove. First you need to tighten the upper screw in order to exclude its free play.
4. Next, begin to clamp the handle of the device. In this case, a smooth leveling of the surface of the damaged section of the body occurs.
5. When the work is completed, the piston comes off and the adhesive residue is removed using the available liquid.

Removing dents with glue

As a rule, after performing the procedures described above, a bulge remains with a depression in the center. You also need to get rid of it - using a fluoroplastic or Teflon core with a blunt tip by gently tapping on the edges of the bulge. After that, the bulge will disappear, instead a dent of a smaller diameter will appear. To remove it, you need to follow the steps described in paragraphs 1-5 of the previous list, however, using smaller diameter piston. In some cases, the procedure will need to be performed three or more times in a row to complete elimination defects on the body of the machine.

Professional kits have a large number of caps of various diameters, thanks to which the masters get rid of any dents. Most cheap kits are limited to two or three pistons, which do not make it possible to get rid of dents of small diameter.

Job vacuum method similar in in general terms with the method described above. The sequence of work will be as follows:

Using a suction cup to remove dents from a car body

1. Wash the surface of the car body and remove all debris and small particles from the places where the dent is located.
2. Attach the suction cup to the dent to be repaired.
3. Lock the suction cup in place (some models have special devices, allowing you to move the suction cup on the surface of the body).
4. Pump out all the air between the suction cup and the body, thus ensuring high level vacuum.
5. After fixing the suction cup in place, you need to pull on it. Depending on the specific model, you can pull directly on the body of the suction cup, or you can rotate a special threaded handle.
6. The suction cup will move and pull the surface of the machine body along with it.

The vacuum hail dent removal method is the most gentle in relation to the paint and varnish coating of the car. Therefore, if the paintwork of your car is not best quality or it has been applied for a long time, then the vacuum method will suit you better than others.

Thermal method of removing dents after hail

The alignment process in this case involves heating the damaged area of ​​the body to a high temperature, followed by cooling, for which they use special means. It is worth mentioning right away that exposure to high temperatures adversely affects paintwork body. Therefore, after returning its geometry, it is often necessary to repaint the treated area.

A powerful building hair dryer is often used to heat the metal. And for cooling - the flow of cold air from the compressor.

At self-fulfillment procedures, be aware of personal precautions, as well as compliance with fire safety regulations.

The thermal repair method is ineffective for very large and small, but deep damage. With it, you can get rid of only medium-sized dents that have a small depth. Besides, using this method may not always lead to the desired results.. The fact is that it all depends on the thickness and grade of the metal from which the car body is made. If it is thick enough, then even heating it to a significant temperature will not achieve a satisfactory result. Therefore, the thermal method of removing dents from hail is rarely used.

Results

The first thing that the owner of a car that has been damaged by hail should remember is that it is necessary carry out repairs as soon as possible. The metal has a “memory”, due to which, after a long time, the deformation will take on a permanent basis, and it will be difficult to return to its original form.

The most convenient ways to remove dents with your own hands - this is glue and vacuum. However, for their implementation, it is necessary to purchase the tools and materials described above. In addition, inexpensive dent removal kits have 2-3 pistons, which is sometimes not enough to repair damage with a small diameter. A most effective method- lever. However, we do not recommend that you do it yourself without proper skill, it is better to seek help from a service station.

Fixing dents without painting is quite difficult if there is no practical experience. The article reveals the main points of this technology.

When can dents be repaired without painting?

The paint coating, in the case of using this technology, must meet certain requirements. The whole process involves multiple manipulations associated with changing the shape of the metal structure. The applied paint must be flexible and durable at the same time. includes in its composition compounds, which are based on polymers, which made it possible to increase the strength properties of the coating. As a result, PDR technology more than relevant.

The paint on cars manufactured in the early 2000s cracks when the shape of the metal changes. In this regard, straightening the damage, without applying a new layer of paint is indispensable. PDR technology is not used if the paintwork is damaged, or restoration work has already been carried out at the place of deformation.

Only those dents that have a more or less integral structure, that is, a smooth shape, without kinks, are subject to restoration. Problems during repair are delivered not by the size of the dent, but by its depth. For example, a shallow dent on the hood, but large in diameter, straightens out more easily than in the opposite case.

Despite the effectiveness of the system, it is not possible to restore the integrity of the surface with a very deep dent. IN similar cases the metal is exposed to excessive stress, as a result of which its shape is greatly changed, while, in most cases, the paint cracks, beyond the possibility of recovery.

Of particular importance in neutralizing the consequences of damage is the location of the dents and the presence of reinforcing ribs. If a dent appears in a section of the body where it is impossible interior work, then it is very difficult to remove the damage. Basically, these are very small areas.

It is impossible to correct the situation in case of body distortion. To do this, it is necessary to restore the integrity of the entire body.

Body dent repair tools

Market automotive products rather rich, on, various kinds of professional fixtures. However, the cost of such equipment is quite high. Consider tools and equipment that are publicly available, not high in price.

To heat the paintwork, it is enough to use a hair dryer, ordinary or building. This is required so that the paint is more ductile and does not crack. If it's summer weather outside, heat, you can do without it.

Vacuum adhesive equipment for dents

These devices are necessary if there is no access to the inside of the damaged area.

Vacuum drawing technology is relevant at the initial stage of restoring the integrity of the surface, when the dimensions of the deformation are large enough. Suction cups are used to do the job properly.

For gluing fungi to a damaged surface, a special gun filled with glue is used. All the necessary kit can be purchased at a hardware store.

To carry out manipulations to restore the concave surface, fungi are used. Their job is to stick to the surface and tear it off. As a supplement, you can use devices made, for example, from the legs of plastic chairs.

Using hooks

It is necessary to prepare hooks of different shapes and sizes. Hooks can be made from strong wire or strong fittings. The main thing is that the material is solid. Low hardness will not allow you to do the job properly, they will periodically bend. Increasing the length of the hook, you need to take care of its hardness. Hardened steel is perfect for this. These devices are used in case of accessibility of the inner part of the body section, through special openings.

Application of cores

Tools are used first repair work, and at the end. For the manufacture of cores, you can use plastic or wood. Their form must be different. Rounded, used on large dents. Minor damage is corrected with more blunt-shaped cores.

Restoring the integrity of the coating without painting

First of all, there is preparation. If there are special holes, then access to them is freer. This is necessary for inserting hooks. The damaged area must be wiped and heated with a hairdryer. Warm metal is more ductile, and paint cracking is almost impossible.

The dent is processed around the perimeter with a round core. The kink points are also processed to reduce stress.

At significant damage, it is required to neutralize the main concavities. If it is possible to get close to the damage from the inside, then the treatment is carried out by hand. Otherwise, hooks are used. If this option is not possible, then adhesive technologies are used. First, fungi or suckers are applied.

Having eliminated the main dent, local areas are processed with a core. After, it is necessary to use small fungi. The work process is quite simple. Having glued the fungus to the place of damage, allowing the glue to harden, it is necessary to rip it off. This is repeated more than once.

Hooks are required to complete the job. If access to the inside is not possible, then the hooks cannot be used. These deformations are quite difficult to remove. Their size can be reduced only with the help of a core and an adhesive method.

This method of repairing damage is quite complicated and requires a lot of experience. One theoretical knowledge not enough. If there is a desire to learn, then you can train for a long time and hard on an ordinary metal sheet, bending it in advance.

Even with the most careful attitude to your iron horse dents and other defects may appear on the body. Many motorists in their entire driving experience at least once, but faced the need to eliminate a dent on a door, hood or fender.

An apple that fell from a tree, a ball of children accidentally got into the car, unsuccessfully opened door, a neighbor in the yard in the parking lot hit the car - only a small part of the causes of defects on the car body. In this case, the question arises: how to remove the dent on the car yourself.

Few are aware that getting rid of such damage is possible in a few minutes. Modern technologies have reached the point that dent repair is possible without puttying, priming and painting. Elimination without painting makes it possible to significantly save, because. for body repairs at the service station they will take a rather large amount. So let's get started.

Varieties of dents

First of all, you need to deal with the defect itself. The following varieties are distinguished:

1. Deep. The depth of the defect is up to 10 mm, but sometimes more. In this case, the damage, as a rule, will not have an oval shape. It will be difficult to remove the dent yourself. It is better to turn to the masters.
2. Shallow. The depth of these dents is not more than 5 mm. If the paintwork is not damaged, then with diligence it is possible to remove the defect on your own.

How to remove shallow damage on car doors, fenders, hood or on the roof and other elements of the car body, we will consider below in the article.

Where to begin?

Before starting the repair, it is necessary to carefully inspect the damage. It is best to start straightening dents, starting with smaller ones, moving on to larger ones.

For successful straightening, the paintwork must be in good condition. If the paint is damaged, it will not be possible to repair without painting. Then the usual straightening method is applied or the part is completely replaced.

Easily removes damage on large and smooth surfaces - roof, hood, fenders, doors. Much harder to eliminate on curved surfaces.

For this procedure, you will need your own tools and equipment. In some cases, it will be possible to get by with improvised means, in others a professional tool is needed. Consider 5 basic ways to remove dents without painting:

1. magnet;
2. Special levers;
3. With the help of a hair dryer;
4. applicator;
5. percussion.

Let's consider each in more detail.

Magnetic removal

Small damage to the car body, which are small depressions without a kink, can be pulled out using a conventional magnet. The algorithm is quite simple. Place a soft cloth between the magnet and the car body to protect the surface from scratches. Having attached a magnet to the edge of the damage, begin to pull it towards you, while moving towards the center of the dent. This method is quite effective.

With levers

This method is used frequently. However, it is worth considering that this procedure performed much more difficult.

A set of levers is bought at the store. Repair is carried out from the inside of the car. Handles, mirrors, trim, which do not give access to damage, are removed.

The lever of the required length is selected, with light and smooth movements we press on damaged place, producing a gradual straightening of the metal.

In no case should levers be used if traditional straightening has been done before. A layer of putty that has appeared on the site of damage will not allow you to straighten the dent on the wing or door.

If the place of the defect was previously puttied, then in this case it will simply fall off.

With a hair dryer

For this you will need:

1. Compressed air or dry ice;
2. Foil;
3. Latex gloves.

This method consists in the fact that under the influence of a temperature difference, the dent is straightened. Due to the change in temperature, the metal first expands and then contracts.

First you need to heat the dent with a hair dryer. It is necessary to ensure that the surface does not overheat, keep the hair dryer at a distance of about 15 cm from the surface.

If dry ice is used, then we isolate the metal section with a defect with foil. This allows you to keep warm for a while. The presence of the foil will not allow the ice to adversely affect the paintwork of the car.

Wear gloves to protect your hands and apply dry ice. To do this, attach a bag of dry ice and move it over the foil until a pop occurs. This usually happens in less than a minute.

If compressed air is used, the jet is directed to the dent. The paint can must be kept upside down. You need to spray it until the metal returns to its original shape.

If the dent did not straighten out to the end, but only became smaller, the procedure must be repeated. However, this should not be done earlier than every other day. This is due to temperature fluctuations to which the damaged area is subject.

Ignoring this fact can lead to damage to the paintwork.

How to remove a dent with an applicator

This method used when it is not possible to get to the damage from the inside. The surface of the dent must be washed and degreased.

Applicators are glued in the center of the dent. A special hot melt adhesive is used, which hardens in a couple of minutes. With the help of a special mini-lifter, the metal is pulled out. After straightening, the adhesive can be easily removed without leaving any traces on the paintwork.

Pull out carefully so as not to overtighten the dent.

Percussion

If you are using this removal method for the first time, we advise you to try it on some unnecessary part.

To do this, you will need a rubber mallet. The procedure consists in tapping metal with reverse side. If this is a hard-to-reach place, special hooks are used.

Conclusion

All ways and methods of removing dents are effective for self repair, however, they do not guarantee that the paint on the damaged area will not burst during operation.

Following our instructions, even a novice motorist can perform minor body repairs. The most important thing is to perform dent pulling on your own only when you are sure of a positive result. Otherwise, it is safer to contact specialists.

Small dents on the car can appear as a result of a minor accident. However, they spoil a lot appearance car, and the cost of repairing the body costs a pretty penny. But small dents on the car can be removed by yourself, following the instructions given in this article.

Method one

If the dent turned out to be subtle (such defects usually occur on the doors and hood of a car), then you can remove it easily and quickly, armed with a hairdryer and a can of compressed air. First of all, it is necessary to heat the damaged area of ​​\u200b\u200bthe body with a hairdryer. Then aim a can of compressed air at the defect. Before starting work, be sure to clean work surface. Remove the inner lining and soundproofing, and also raise the glass to the stop.

If the dent turned out to be more serious, then you will have to disassemble the door trim or even remove the car door. To do this, you will need a rubber and regular hammers, a wooden block measuring 10x20 cm, as well as a clean rag. Start straightening the dent by lightly tapping it from the inside. If the dent cannot be repaired, then wrap the bar in a rag and repeat the procedure until the surface is completely leveled.

After that, it will be necessary to polish the repaired surface of the body.
To eliminate a deep dent, it is necessary to act on the bar directed to the center of the defect, alternately with a rubber and an ordinary hammer. After completing the procedure, it is necessary to check the level of concavity of the metal. Then plaster and putty the repaired surface of the car body, prime it and polish it.

Method two

Before proceeding with the removal of a dent, determine its type. This method is applicable only to those dents that do not have sharp edges and do not affect the body stiffeners. To repair a small dent in a car fender, you will need a football or basketball with a camera and a bicycle pump.

Examine the door from the inside to find a dent. Position the deflated ball between the dent and the frame. Gradually begin to pump up the ball. The principle of operation of this method is based on the fact that when filled with air, the ball will gently straighten the dent. After removing the defect, release the air from the ball to remove it.

Straightening

In order to eliminate a small dent on the wing or car body, you can use the third method. To do this, you will need a rack or hydraulic jack, extensions of various lengths such as pieces of a thick-walled pipe or two corners welded into a square (depending on the type of jack), as well as a leveling hammer, powerful support and several solid wooden blocks.

Now you can proceed directly to the elimination of the dent. It is necessary to prepare the damaged surface for repair, and to do this, remove the wheel from the corresponding wing of the car. Then you need to put a strong support under the jack socket. One of the bars must be placed under the wing on the stiffener, and the second - in the rear of the wing.

After that, put a suitable extension on the jack and insert this structure between the bars. Start working as when lifting a car, that is, stretch the dent from the inside, bursting the wing. Then, holding the jack in the same position, flatten the dent by tapping lightly on the inside of the wing with a hammer while applying support from the outside of the wing.

If, nevertheless, a slight swelling remains under the stiffening rib, then to eliminate it, it is necessary to wrap a wooden block with a rag, attach it to the defect and, lightly hitting it with a hammer, eliminate the defect. The secret of the ideal dent removal is that if the stiffener is in the straightening zone, then it is necessary to start the repair from it.

First of all, you need to straighten the stiffener to a normal state, and then proceed to other damaged areas. After the repair is completed, it is impossible to immediately loosen the jack, on the contrary, it is necessary to tighten it a few turns so that the wing does not undergo deformation. After that, you can remove the jack.

When performing straightening, one more rule should be remembered: you need to start it from the edges of the dent, moving in a circular motion to the center. For correct execution straightening, it is necessary, first of all, to determine the boundaries of the dent. To do this, cross its surface with a straightening file.

When removing small dents, do not leave the car on a jack. It is best to replace it with reliable stands. Immediately before work, check the serviceability of all tools. Hammer handles should be even and smooth without cracks or bumps. Repair work should be carried out in mittens or cotton gloves.

After straightening the dent, the metal must be puttied. Before puttying, it is necessary to degrease the surface and allow it to dry properly. There should not be a drop of moisture on the surface. Putty should be carefully applied with a spatula in thin layers. Let it dry and then smooth with sandpaper. Before the next layer of putty, the surface sanded with sandpaper should be degreased again. Then repeat the procedure.

The final stage in the elimination of small dents is painting the repaired area of ​​the body. It should be painted with a spray gun or spray can. In this case, it is not necessary to paint the entire wing, but only the damaged surface. After that, cover the painted and dried surface with primer.

Before priming, degrease the painted surface and allow it to dry properly. Shake the primer can and blow out the surface, making sure that the primer does not spread. The primer should be sprayed over the entire surface, evenly covering it. Cover the surface with primer twice with an interval of 15-20 minutes to dry. Top coat the surface with varnish three times, and after a month cover the surface with car polish.

Dents on a car can piss off even a fairly patient driver. There can be a lot of reasons for the appearance of such “unpleasant” guests: there is heavy traffic, accidents, and inattentive, sloppy parking. And, how did we forget about atmospheric precipitation in the form of icicles or hail, from which not a single car is insured. In the end, sooner or later, the driver will face a very important and rather serious question about how to remove dents efficiently, imperceptibly and, most importantly, inexpensively.

As a rule, earlier it was possible to get rid of dents only thanks to straightening and repainting. Today, to the delight of every driver, new body restoration technologies are used, which help to do without expensive repairs.

1. Repair of small dents without painting

The method of completely repainting the entire element is now considered obsolete. This method also requires special financial costs and precious time. An excellent alternative to this method today is the so-called PDR method(paintless dental repair). It can be used if the paint layer of the body is not damaged. Translated from English, it means the repair of defects without painting.

Looking back, the paintless dent removal system was developed by Mercedes-Benz over 20 years ago. At that time, this technology was used to remove body defects that were formed as a result of careless handling at the time of assembly on a conveyor in workshops or during pre-sale preparations in car dealerships.

Great popularity and impetus to further development, namely the creation of new systems and tools, straightening without painting "healed" in the United States, from where it came to Ukraine several years ago. Today, the Americans are insisting with might and main that this technology is their direct creation. So, let's understand what this PDR technology is and what are its features.

It is important for every driver in the future to know that paintless dent removal, magnet dent removal, paintless dent removal, paintless straightening, glue dent removal, vacuum straightening - this is all PDR technology. Today, the technology of removing dents without painting (Paintless Dent Repair - PDR) can be safely called a real art or jewelry straightening. It allows you to simply "pull out" all the dents without using repainting the element.

If you watch the work of a master who uses an expensive tool to repair dents, you can say that it looks like a frame from fantasy movie, and in real life such repair is not possible. You just see dents disappear in front of your eyes almost anywhere in the car body, which so recently irritated the owner of the car and acted on him like a red rag for a bull.

After the repair is completed, you need to look very carefully at the place where there was a dent until recently, because it will be almost impossible to detect signs and even the place of a defect. As many experts like to say: this is not a “miracle”, but “ high quality work".

In general, green light for implementation new technology gave development and active use in the automotive industry paint and varnish coatings based on polymer compounds. Thanks to the latter, the body coating retained flexibility and strength even with fairly serious body deformations.

So, let's summarize what are the main differences between dent removal technology and traditional, standard body repair. So, to begin with, it is important to say that when using the repair of irregularities without painting, any part gains its original appearance and the paintwork is not damaged.

Secondly, the repairman does not need to use putty, abrasive materials, primer and much more, which is usually put into operation when repairing damaged parts. Thirdly, a rather important advantage of modern technology is the fact that the factory coating is preserved on body parts, and if you want to sell your car in the future, you will only be in the black, because it is quite easy to recognize a painted part today.

Also, during this operation, you do not need to remove individual parts from the body and no further disassembly is required. And this, as they say, saves time and nerves, which are spent a lot with ordinary straightening. Also, this approach prevents the appearance of new squeaks in the car.

How does the process of removing dents in the walls of any technical center go? The entire repair involves the operation of special levers (hooks) of various configurations, due to which pressure is exerted on the inner surface of the metal. In order to choose the right dent repair strategy, the master must take into account all the parameters of each dent, as well as its specific features. Here, the location on the car body, the length, width, depth of the dent, the quality of the paintwork, as well as the thickness of the metal of the car body are taken into account.

After the master has taken into account all the specific features and parameters of the dent, he proceeds to the main work: with gradual smooth movements, the specialist gives the metal of the car body its original shape.

It is also important to take into account the fact that it is possible to do paintless dent removal only in cases where the paintwork is not damaged or there are no large parts on the car elements. deep scratches. It is also worth remembering that elements with poor quality Factory paintwork, which usually make up the body of old cars, or cars that have already "survived" traditional body repair, is not amenable to removing dents without painting the car.

It is necessary to remove a dent without painting very carefully and carefully so as not to damage the “native” paintwork. Therefore, experts recommend seeking help in such a problem in special repair centers.

In general, we can say that PDR technology has many advantages in its arsenal. Firstly, it does not require a large amount of money, and also does not take much time. As practice shows, straightening without painting takes 3-4 hours, and possibly even less, depending on the location of the dent area. If we talk about the quality of repair work, then it is not inferior to a complete repaint.

2. Features of dent repair

Now let's talk about some of the features of dent repair on body parts. So, if you suddenly fell under hail and, as a result, deformed areas appeared on your car, you need to pay attention to the fact that those are removed using a special lever various lengths and forms. Due to the variety of levers, you can choose exactly the one that is needed according to the individual length and bends of the technological hole in machine body for direct impact on the dent from the inside.

As a rule, direct access to the dent is not always possible. In this case, it is supposed to dismantle the skin and other body parts. Thanks to this operation, you can remove the deformed area.

These works are carried out so simply that they can be done independently, without the help of specialists. Moreover, if the deformed area on the bumper is easily accessible, you can not resort to the help of a specialized tool.

What you need to do is to very carefully work on the dent using reverse side rubber mallet. After the operation, you can get a fairly flat surface. In order to really please you with the result, you can purchase a special set with hammers of various sizes, each of which specializes in a certain type of dent.

3. How to pull out a dent without painting

Car owners very often ask rather interest Ask: what kind of dents can be "pulled out" without painting? In this case, experts advise to diagnose the damage, that is, to determine the nature of the dent. If the driver finds on his car a peeling paintwork at the site of a defect, or the presence of through holes in the body, he needs to partial renovation body.

If we talk about how to pull out a dent, it can be argued that there are several ways to do such an operation. The most popular way to "remove" dents is mechanical straightening. Thanks to him, you can easily carry out the elimination of defects in such places of the body, which are difficult to reach, and also where it is impossible to use special tool for paintless dent repair.

In the process of mechanical straightening, the master puts into use special levers and special vacuum hoods (basically, such auxiliary tools are used to get rid of small damage car body). Taking advantage of a strong pressure drop in this case, you can return the body to its original, former shape. How is leveling done with a lever? Pretty simple.

The master selects the lever that is the most ideal in size, then plunges it into a special technological hole on the body.
