Pulling out dents on the body is a simple technology that does not require painting. We remove small dents on the car ourselves

This simplest technology contains absolutely no hard-to-find parts or tools that would need to be bought or ordered. We need only two things that can be found without problems in any garage. It's a waste valve and a hot glue gun. And then you can do without a gun, melt the glue in another way.

How to remove a dent in a car?

So, let's begin. We look at the dent. We need to find the middle of this dent. Once this is done, we take an unnecessary valve (if you don’t have one, ask a neighbor) and degrease with alcohol or gasoline.

Then apply hot glue to the valve cap. If you only have glue without a gun, then heat the valve with a gas burner and smear the glue.
Glue the valve in the middle of the dent. Hold for a few seconds with your hand, wait until the glue grabs. We release and wait another 3-5 minutes until it cools completely and hardens.

Further, so that the valve axis does not slip out of the hands, we take it with a rag or in mittens. And with effort we pull in the opposite direction from the dent. Rather, we even pull. Since the dent has internal tension, it itself tends to straighten up, but the strength of the tension is not enough, and in this way we help them to return to their normal state and relieve this tension that has arisen.

How to remove hot glue?

In general, the dent straightened out. Now it remains to remove the valve, if it has not flown off itself and the adhesive gasket.

If the paint on the place of the dent is factory, take acetone, spray on the place of gluing and carefully remove everything. If the place has already been painted, take better alcohol.
Here is such an easy way to quickly straighten a dent on a car with your own hands!

Continuous improvement of car bodies, in particular, the use of more thin metal, but with high strength indicators, as well as the use of modern paint and varnish coatings with sufficient flexibility, made it possible to significantly facilitate and reduce the cost of the surface restoration process. Nowadays, body dent removal without painting is increasingly being performed.

Of course, to restore the surface of the body when a deep dent has formed or has been damaged paintwork without subsequent painting work will not succeed. But it is quite possible to level the surface with shallow dents.

Advantages and disadvantages

The advantages of removing dents from the body without painting damaged item can be attributed:

• The speed of work (with a correct assessment of the nature of the damage and compliance with the technology, a dent on the body can be removed within an hour);
• Low cost of restoration (lack of painting work significantly reduces the cost of work);
• After leveling the surface, the traces of the dent are imperceptible (since painting work is not carried out, it is no different from others on the body);
• Using multiple methods gives high efficiency works;

But it should also be pointed out that not all dents can be restored without subsequent painting of the element. Dent removal cannot be applied if:

• The paintwork was nevertheless damaged as a result of the impact;
• The dent is very deep (as a result of a strong blow, the metal has changed its structure - it has stretched out a lot, and it will not be possible to easily level the surface);
• The body received a severe deformation;
• The geometry of the dent is very complex and has sharp creases;
• Dents are formed on the edges of the doors, hood, trunk (since the edges are usually well welded and use right tool impossible);
• The dents are formed on the roof pillars;
• The car has low quality paintwork.
• The car is quite old and modern materials were not used on it;

Although the use of this recovery method is rather limited, it is becoming more and more popular.

Paintless dent removal. Methods and tools

Straightening dents on the car body, as already noted, is carried out by several methods.

• The first method includes the impact on the dent with inside body. If you look from the inside - then on the bulge.

IN this method two types are used. If a dent is formed on a surface that is easy to get to from the inside - wings, trunk lid, then hammers with a rubber head are often used. Specialists usually have a whole set of these hammers, which makes it possible to apply each to a specific type of damage.

The second type of tools - all kinds of hooks, clubs, levers. They also smooth out the dent from the inside. This tool is used when leveling the surface, but in hard-to-reach places. Each car body has a large number of technological holes into which hooks and levers are launched, and then the dent is leveled by force on them.

• The second method of removing a dent without painting is the impact on it from the outside of the body, that is, from the side of the dent. For this, special extractors are used.

Vacuum extractor for straightening a dent

For small dents, vacuum hoods are used. They are suction cups of different shapes, for use on different dents.

If the dent is significant, but it is possible to eliminate it without painting, then glue-based applicators are used. In fact, these are the same suction cups, but they stick to the dent. The use of glue provides the proper force to separate the applicator from the metal. The applicator fixed on the dent is pulled out with the metal in the place of the dent by the same microlift. Applicators, like suction cups, have different shapes for use on dents of different nature.

An important factor is that equipment, both for leveling the surface from the inside and from the outside, can be freely bought, but you need to be able to use it correctly.

Stages of work on straightening dents

So, what should be considered if there are dents on the body that need to be repaired, and there is the required tool:

• If it is possible to use hammers, the blows to the dent are not strong, you can use wooden stops wrapped with rags on the other side from the place of impact. These stops will reduce shock loads.
• When using a set of hooks, sticks, it is important to choose the right tool, as well as to choose the right place for the tool to impact on the dent. When using these tools, you can first practice on a suitable piece of sheet metal. It is important to understand how to choose the right place of impact and the force of pressure or impact.

1. Using the second method is somewhat simpler, since the state of impact on the dent can be assessed visually. The force of impact, which is created by the microlift, increases gradually, so it is easier to control the process than, for example, when leveling with hammers.
2. With this straightening method, it is important to decide whether the use of a vacuum hood will be enough and whether its pressing force against the metal is enough to level the surface, or is it still better to use an adhesive-based applicator.

In general, these dent removal methods are very effective under certain conditions. But their use requires certain knowledge and skills, as well as the required tool. The main condition for leveling the surface of the body without subsequent painting is the correct assessment of the damage and the correct choice of the method of repairing the damage.

Paintless Dent Repair (PDR) This technology allows you to perform paintless dent removal using special tools:

Dent Puller

The first condition for a successful business is a set of PDR equipment. It includes:

1. Hooks with different shape, dimensions and length. With the help of them, the metal is returned to its original shape by introducing them into the technological holes on the body, and applying certain efforts from its inside.
2. Adhesive equipment. Glue sticks, glue fungus of various sizes (suction cups for pulling out dents), glue remover.
3. Various accessories. A set of cores, plastic plugs, puffs, wedges, stops, pendants and LED lamp.

However, it should be understood that the result directly depends on the quality of the tools.

Do-it-yourself paintless dent repair with PDR

The second condition is skills. A beginner is unlikely to be able to cope with the task without experience. The theory can be obtained from the instructions and video material presented below, and practiced on an old, unnecessary body.

Instructions on how to straighten a dent on a car using PDR technology:

1. Clear work surface.
2. Relieve metal stress at bends using a hammer and cores.
3. Repair the dent with a vacuum or glue.
4. Straighten the remaining dents from the inside of the body with the help of hooks, defining them from different angles of light.

The whole process is shown in the video:
How realistic is it to level dents without painting in garage conditions, without experience? Let's show with an example how it turned out to straighten a small dent on the wing Hyundai Elantra. It took: a technical hair dryer, a rubber mallet, polish, a plastic drift and an old hockey puck.

Procedure:

1. Remove the fender liner so that you have access to the dent from the inside.
2. Heat the area of ​​the dent on the wing with a hair dryer to 50 ° C so that the paintwork does not burst.
3. Relieve metal stress at bends by lightly tapping the dent through a plastic drift.
4. Repair the dent by applying pressure inner part palm wings. If the dent is without ribs, then it should simply "spring" back into place.
5. Straighten out the remaining unevenness of the fender by periodically warming the fender with a hair dryer and tapping around the dent.

Conclusion

PDR technology has been around since the late 1960s, but it has only recently gained widespread use. With the help of this technology, both minor and complex defects on the car body are eliminated. However, not all dents are feasible for PDR, such as door sills, edges of trunk, hood, door elements, roof pillars and other sharp creases. As practice shows, straighten a simple dent you can do it yourself, using an improvised tool (to be sure, you can practice on unnecessary parts from a landfill). However, complex damage to the body can be repaired only by professionals.

By the way, do you know how

Dents on a car are known, perhaps, to every motorist. It would seem that this is serious, because you can simply drive the car to the service station and entrust everything to specialists. But you should also take into account the fact that you will have to leave the car for several days and pay a lot of money. Therefore, it makes sense to learn how to eliminate such defects on your own.

We remove the dent with our own hands

Types of dents

First you need to decide on the dent itself. It is customary to distinguish between such damage of the following types:

• deep - dents with a depth of 10 mm, sometimes more. As a rule, such damage does not have a clear oval shape. In this case, it is impossible to eliminate the dent on your own;
• shallow - the deflection of the metal is not more than 5 millimeters, the paintwork is not damaged. Such defects can be eliminated independently.

Body Diagnostics

Before proceeding with the repair of the car itself, you need to carefully inspect the body of the car. Do it better with good light- so all the damage will be

Please note that if more than one dent is found on the surface of the car, start repair work follows with the most minor damage, gradually moving to the largest.

Also, before pulling, make sure that good condition paintwork. If the paint is badly damaged, straightening without painting will not work. In this case, the defect will have to be removed in the traditional way of straightening the car.

Straightening methods

Put away mechanical damage on the body of a car in several ways:

• through a set of levers;
• magnet;
• applicators;
• heating followed by cooling.

Each of these methods has both its advantages and disadvantages.

Please note that it is impossible to perform such work on your own if:

• the scale of deformation is large;
• the car is very old;
• damage is in the threshold area;
• heavily damaged LKS.

In such cases, you should contact competent specialists.

Straightening with a magnet

Using this method, removing a dent from a car is the easiest. Please note that before starting the repair, you need to put a soft material under the magnet. This is necessary so that the surface of the car is not scratched during the leveling process.

The magnet must be directed from the edge of the dent to the center. At the same time, you need to pull the magnet towards you. If the dents on the car are shallow, then this way you can easily make repairs without painting.

Lever method

The method of straightening the surface of a car without painting with the help of levers is used more often. But it should be noted that this process is much more complicated. Therefore, before straightening your car, it is better to practice on other surfaces.

First you need to purchase a set of special levers. On average, there are about 40 pieces. It looks something like this:

Levers for straightening a car

To start the repair, you need to provide free access to the place of damage. To do this, all third-party elements (skin, mirrors, headlights, handles) must be carefully dismantled.

Dent removal is carried out only from the inside of the vehicle. To do this, you need to pick up a hook optimal length and gently press on the place of the recess, gradually leveling the metal.

This technology without painting can also be used if classic straightening has already been used. It is contraindicated to use the method with hooks if the surface of the car has previously been puttied. In this case, this layer will simply fall off.

Leveling with applicator

The applicator method is used if straightening from the inside is not possible.

Before starting repairs, the surface of the machine must be thoroughly degreased. Further, rounded or square applicators are attached to the surface with glue (along the edges of the dent). central part damage is leveled with a mini-lifter or a brace with central screw. This must be done very carefully, as you can easily "drag" the dent.

It should be noted that this pulling method does not require large material costs and special skills. It's easy to do it yourself.

Pulling with applicator

Heating-cooling

For this method of editing at home without painting, you need to have:

• building hair dryer;
• compressed air;
• personal protective equipment (gloves, respirator);
• polish.

The essence of such a repair of the vehicle surface without painting is that due to the temperature difference, the metal is straightened. Editing is carried out according to the following algorithm:

• the dent heats up with smooth movements along the radius;
• with help compressed air the dent cools down.

If the damage is of medium size, heating should be carried out in several places. At the end of the process, the treated area must be treated with a polish. Repairing a dent in this way is very simple and inexpensive.

Conclusion

Do-it-yourself body straightening does not require high costs and special skills. Using the above methods, even deep dents can be removed. The main thing is to make a correction with your own hands only if you are sure of a positive result. Otherwise, it is better to contact specialists.

All three methods are quite simple, they can be done by hand, as they do not require expensive equipment and special skills. Removal of dents without painting is carried out by vacuum, glue and PDR technology. To begin with, it is necessary to inspect the damage. Paintless dent repair cannot be carried out if:

• damaged paintwork;
• the deformation has a complex shape with deep, sharp fractures;
• the deformed area was already painted, and the painting was done poorly;
• the car has been in operation for more than 15 years and microcracks and traces of corrosion are visible on the paintwork.

In all other cases, you can straighten the dents with your own hands.

Pulling out dents is done using special set Pops a Dent.

It includes a special plastic rocker. It has wide legs with soft polymer sponge at the ends to prevent damage to the surface. Several nozzles of various sizes, it is their soles that are glued to the defect and straighten the dents. Hot-melt gun and a few sticks with silicone hot-melt adhesive.

• Using this device, removing a dent with your own hands is quite simple: We degrease the defect and wipe it dry. There should be no dust on the surface.
• We quickly apply the melted glue to a clean nozzle and press it against the deformed surface, as if twisting it left and right a quarter of a turn.

ATTENTION! The glue must necessarily come out through the technological holes in the sole of the nozzle, this will give the mount additional strength.

• Cooling time 2-3 minutes.
• We pass the stalk of the nozzle into the hole.
• We wind the lamb onto the thread and begin the slow straightening of the dent to the level of the surrounding metal of the body.
• Leave for 5-7 minutes in this position.
• We unscrew the lamb and remove the arc.
• We heat the plastic building hair dryer at the lowest temperature.
• We separate the nozzle by slightly scrolling it to the right, to the left.

However, if you drive carefully and dents are atypical damage for your car, buying the whole set is completely unnecessary. It is enough to purchase a glue gun, which can be useful on the farm. The arc can be easily made with your own hands from wood, and as a nozzle, use a regular screw with a wide hat. Pulling dents will happen a little differently:

• glue is applied directly to the defect;
• a bolt head is applied to the molten mass;
• wait a minute, one and a half, so that the plastic grabs slightly;
• a new layer is applied over the cap and the old glue so that the layers stick together.

The further process of removing dents on the car will occur in the same way as described earlier.

Vacuum

Removing dents without painting by the vacuum method is similar in process to the adhesive technology. However, it has one indisputable advantage over it. After the repair is completed, there is no need to remove the adhesive, risking damage to the paintwork or re-deforming the surface. Removing a medium-sized dent on a car is done using a vacuum suction cup. Various Models have different soles. The ideal option is considered to be the case when the sole of the suction cup is slightly missing from the border of the defect.

The preparatory process is limited only to cleaning the work surface. Vacuum is created in the installed suction cup using an electric or manual pump. Once a tight and secure fit is achieved, the hose is disconnected and the dent repair can begin. After the surface has taken original view, a special valve opens and the suction cup is easily removed from the car body.

PDR Technology

This process is the most difficult to do by hand. It will require a set of rather expensive, special tools - levers.
This paintless dent repair is used for extensive and complex damage. The process consists in exposing a dent on a car from the inside of the body surface. If necessary, the inner lining is removed and the parts that interfere with access are dismantled. The hooks used to remove dents from a car come in a variety of shapes and lengths. Their working parts, which directly affect the metal, are bent at different angles.

• Before straightening a dent, the work surface is cleaned.
• In places of bending, damage relieves the stress of the metal.
• The part is heated with a building hair dryer to 40-50°C.
• The edges of the bend are slightly tapped through a plastic gasket (punch).
• Alignment of dents is carried out by pressing on the metal surface from the inside.

The most appropriately shaped lever is inserted into technological hole, scrolling the handle, with a pressing movement act on the surface. Straightening dents with hooks requires certain skills and accuracy. In professional kits, there are special wedges made of polymers that are placed under the metal of the hook so as not to deform the elements of the car. See also video
