Deans on the car are known, perhaps, every motorist. It would seem that here is serious, because you can simply drive the car to the service station and entrust all specialists. But it is necessary to take into account the fact that the car will have to leave for several days and pay no little money. Therefore, it makes sense to learn how to eliminate such defects on their own.
Clean the dent with your own hands Types of dents
To begin with, decide on the dent. It is customary to distinguish such damage to the following types:
- deep - dents depth from 10 mm, sometimes more. As a rule, such damage does not have a clear oval form. In this case, it is impossible to eliminate the dent on its own;
- shallow - metal deflection is no more than 5 millimeters, the paintwork is not damaged. Such defects can be eliminated independently.
Body diagnostics
Before proceeding with the repair itself, you need to carefully examine the body of the car. Do it better with good light - so all the damage will be
Please note that if not one dent will be detected on the surface of the car, start repairing work with the most small damage, gradually moving to the largest.
Also before starting pulling, you should make sure in good condition of the paintwork. If the paint is badly damaged, the rattling without painting will not work. In this case, the defect will have to delete the traditional method of car rating.
Removing dents without painting Methods of Richtovka
Remove mechanical damage on the car body in several ways:
- by set of levers;
- magnet;
- applicators;
- heated with subsequent cooling.
Each of these methods has both its advantages and disadvantages.
Please note that you cannot fulfill such work yourself if:
- scale of deformation big;
- the car is very old;
- damage are in the area of \u200b\u200bthe threshold;
- light damaged by LCS.
In such cases, refer to competent specialists.
Bumper repair do it yourself Richtovka by magnet
With this method, remove a dent with the car easier. Please note that before starting repairs, you need to put a soft material for a magnet. It is necessary so that in the level of alignment the surface of the car did not scratch.
Magnet should be directed from the edge of dents to the center. At the same time, you need to pull the magnet on yourself. If dents on the car are shallow, then you can easily repair without painting.
Richtovka car with a magnet Method with levers
The method of straightening the surface of the car without painting with levers is used more often. But it should be noted that this process is much more complicated. Therefore, before denying your car, it is better to practice on other surfaces.
First you need to purchase a set of special levers. On average, it has about 40 pieces. It looks like this:
Richtovka car levers To start repair, you need to provide free access to the place of damage. To do this, all third-party elements (trim, mirrors, headlights, handles) must be carefully dismantled.
The elimination of dents is made only on the inside of the vehicle. To do this, it is necessary to choose a hook of optimal length and gently adjust to the place of deepening, gradually align the metal.
This technology without painting can be applied in the event that the classical richt is already applied. The use of the method with hooks is contraindicated if the surface of the car has previously placed. In this case, this layer simply falls off.
Alignment by apple
The applicator method is used if it is impossible to perform straightening from the inside.
Before starting the repair, the surface of the machine must be carefully deguted. Next to the surface of glue (along the edges of dent), round or square applicators are attached. The central part of the damage is aligned with a mini-lifter or brackets with a central screw. It is necessary to do it very carefully, as you can easily "drag" dent.
It should be noted that this method of pulling does not require large material costs and special skills. Make it yourself easily.
Pulling with an applicator There are several ways to reflect dents based on the use of various tools. In this case, these work is carried out according to one principle consisting in the fact that the body on the damaged area is physically impact. The following article discusses the basic methods of car body alignment.
Mechanical alignment from the inside
Using this technology allows you to align defects without painting. In this case, vacuum hoods and levers are used. Alignment of dents on the car body in this way based on pressure drop. Works consist in the fact that a suitable lever, that is, giving up before the defect, is placed in the car body opening and pressed on it until the damaged area returns to its original state. The return of the material to its original state is usually accompanied by a click.
Pressure should be reached carefully to prevent the metal bending in the opposite direction. If this happened, the site can be aligned with fluoroplastic bump.
If the dent is located close to the body opening, then it can be pressure from the inside without using the lever. However, not always the car body is damaged near the technological holes, and it happens to a defect to get to the inside. In the absence of such an opportunity, damage alignment is carried out by one of the following methods.
Defense Magnet
It should be noted that this technology is suitable for straightening only small damage. In the process of operation, the magnet is moved along the surface of the damaged area from the edges to the center of the dent, pulling it on itself. To avoid damage to the paint coating under the magnet, it is necessary to put a soft rod.
External glue technology alignment
This method is also called vacuum, and the essence of this technology consists in stretching dents with a piston, fixed on a damaged part of the body using glue. However, it is possible to use and non-professional devices represented by suction cups. The applicator is fixed using glue on a damaged body place. Upon completion of its drying, the central point of dents is pulled by a mini-lifter. The sucker is used by the same principle.
This method can correct the defect, but not eliminate it completely. In addition, it is not recommended to use such technology to align the parts with cracks, since it is possible to detach the metal.
In general, the adhesive method of straightening dents is considered one of the most simple and rapid.
Correction of defect thermal influence
The method under consideration involves the use of a constructional hair dryer and a sprayed aircraft. Also need protective equipment in the form of glasses and gloves, since work is carried out at a temperature of from 300 to 650 ° C.
This technology is based on the pursuit of metal to return to the initial state. At first, the damaged section of the car body is heated by a construction hairdryer, and then cooled by a can be cooled (the temperature of the air emitted is -78 ° C). Such a temperature difference leads to the return of the metal into its original state.
In some cases, if the body has a large damage, this operation is carried out at several points. For a round dent, their choice is carried out along the radius, and for oval - by narrow side. If there is a defective area of \u200b\u200bhard elements, the alignment starts with them. If the thermal effect does not allow to completely get rid of the damage, this method is combined with the tapping of the Cyan. At the same time, to protect the paint coating of the body in the place of the defect covered with soft rubberized material.
Percussion
This method of Richtovka involves the use of rubber inquaries of various sizes and hooks. It is most likely to catch up a damaged area on the back of the defect. At the same time, with an external apply wooden bar, so that the metal beats can be prevented in the opposite direction.
If there is no access to dent from the inside, then hooks or screws are used. These fixtures are inserted into the pre-drilled holes in the center of the defect and pull out. Upon completion of the opening, the holes are applied or brewed, then rubbed and stained.
In the absence of skills, it is advisable to test this method on any unnecessary detail.
Upon completion of the performance, the restored part or its fragment is polished. This method is usually used if the body has large dents.
POPS-A-DENT
This name is a specialized tool kit designed to align dents. It includes nozzles, plastic globe glue, and repair is carried out like this:
- The center dents are preventing preventing.
- Then heated glue. To do this, the glue rod is inserted into the gun and connect it to the electrical network.
- The glue is applied to the rubber nozzle and glue it with circular motions clockwise into the damage center.
- After 2-3 minutes, the bracket is installed on it.
- Next, with the help of the lamb, it is screwed to the nozzle until the defect is straightened.
- Upon completion of the work, the device is not removed from the car body for 5 minutes.
The body metal of foreign cars and domestic cars in thickness rarely exceeds 0, 6 - 0.8 mm, so it is easily deformed, forming dents of various shapes. For a long time, the main way to remove dents was a manual richt that requires dismantling the body detail of the car. Modern techniques allow repairing a number of dents without dismantling and painting body elements.
How do dents appear on the bodies?
The dent on the passenger car may appear on a variety of reasons. The thickness and softness of sheet steel, aluminum used for the production of body parts is insufficient for resistance to impacts or pressure. Body metal hood, roofs, trunk lids, car wings and doors deformed:
- if you quickly rely on the car with your elbow or knee;
- from road debris, stones;
- when falling from the roofs of solid snow comes, icicles;
- from blows of roadside branches;
- when hitting the door of the next car;
- as a result of unsuccessful parking (at rear departments on building blocks, poles, walls, road fences);
- from hooligan actions (shocks by car hand, foot);
- with any road accidents.
Without considering severe body damage in an accident, which are accompanied by metal gusts, a significant part of the dentin is characterized by the preservation of the paint layer. Therefore, it is possible to repair them without painting, partially disappointing the body equipment.
Local repair techniques
Local repairs are customary to be called work with a separate body part, which are carried out with a partial painting body element or without painting. Local repair is cheaper and faster than hand straightening, does not require body disassembly. For non-removable body parts (roofs, rear wings), local repairs are preferable, since it does not require complex work - disassembly of the cabin, trimming of the element, welding, assembly operations.
Basic PDR technology
The PDR abbreviation is used to reduce the long name of the technique. The literal translation of the term "Paintless Dent Removal" sounds like "Consumer removal of dents". The method for the first time applied the master of the body shop "Mercedes" Oscar Flyg, discovered that from the inside, the metal can be straightened with a long lever of spring steel. The lever will start in the technological holes of the body part through the technological holes or under the removed cabin trim, the trunk.
From the middle of the last century, dozens of forms of levers and hooks have been developed, but the essence of the method remained the same. For deep dents, except the lever, the hoods are applied by vacuum. When the maintenance of aluminum parts, the induction devices warming up aluminum currents of high frequency are used simultaneously with the main procedure.

Glue, vacuum hood
In case of adhesive hood on a dent, the thermoclaim glit "fungi", the pistons for which the metal is pulled out by the reverse hammer. The vacuum method uses suction cups of various sizes, from under which the air is pumped up with a pump or compressor. The pressure difference between the outer and the inside of the dent pushes the metal outward. After supplying air through the valve, the suction cup is removed, without damaging LCP.
Adhesive and vacuum hoods are well refined shallow dents of the right shape. When editing extensive dents, the technique is combined with a basic lever hood.
What dents can not "pull out":
- if there are gusts of metal;
- dents on firewalls, kanta, the edges of the body part;
- dents on thick-walled or inaccessible details;
- cheats authemali;
- shapatle places (putty peeling together with paint).
For such damage, a spotter extract is used (requires a local painting of the renovated place) or manual straightening with disassembling body element.
Is it possible to finally straighten a dent?
A lover of garage repairs can independently straighten a dent, but it will require training and certain financial expenses.
Need:
- Purchase expensive equipment set for PDR.
- Repeatedly practice to purchase skills on spoiled doors or wings.
Handicraft methods that can be found in the Internet materials can bring more harm than good. Repairs with a construction dryer, plumbing canto, homemade or cheap suckers do not bring results. The inept use of such techniques causes the authemal detachment. In addition to a small dent, bloating appears on the body.
Quality removal of dents without painting Perhaps only in an equipped auto repair shop, experienced specialists should carry out work.
