If there are through holes formed by metal corrosion on the body of your car, and you do not want to pay 4000-5000 rubles and more for repair 1 details, you can try to repair it yourself.
Please note that the tips described in this article are not professional, and are suitable only with the amateur repair of your car.
It is not difficult to do it on its own, and the stages of repair parts are described in order with the photo overview:
1) Take the newspapers, and with the help of painting tape, and close the part of the part that is not planned to be repaired. This is done in order to protect the car body while stripping from rust.
2) With the help of a metal brush, sanding skins (grain 120), remove rust to parts, as well as clean the paint on the territory adjacent to the through hole by 1.5-2 cm.
3) Prepare a piece of sheet metal, and cut with scissors to metal to the desired size. If you manage to choose a piece of metal with a corrugated surface from 1 side it will be a big plus.
4) Secure, cut out a piece of metal, from the inside of the part. To do this, you can use in several ways:
If there is access to the inside of the part, you can brew using point welding.
If there is no access, you can use the mounting foam and special glue. For this, sewage inside the part of the hole and apply the appropriate glue on the embedded piece of metal.
(The last way is not quite correctbecause Mounting foam is able to cause corrosion parts from the inside, and glue to glue a piece of metal is incorrectly incorrectly, so we use this option in exceptional cases if the car is not sorry).
5) Prepare a car putty with a hardener, and distribute it in accordance with the manufacturer's recommendations. Putty after breeding with a hardener is suitable for work within 2-3 minutes.
6) Apply the first layer of putty on the repaired area. Let the putty dry dry.
7) Retire again with a hardener again, and apply a second layer of putty, to the repaired area. Let the putty dry dry.
8) Again, spread the putty with the hardener, and apply the finishing layer of putty on the repaired area. When applying the finish layer. Try not to leave divorces and stripes.
9) With the help of grinding paper (800 or 100 grain), moistened in water, is stabbing the repaired area. When identifying defects on a putty: scratches, snaps, etc., re-apply a layer of putty, on a repaired part and after drying, repeat grinding.
10) We again take the newspaper and painting tape, and protect the part of the car that is not repaired. Apply primer.
13) The item is renovated.
Perform body repairs yourself, and even in the conditions of the garage, a rather difficult task, however, like any other work on the repair of the car with your own hands, especially for a novice vehicle.

How to prepare the body to paint?
The preparation of the body surface plays a very important role in its further color, as no paint system can give good results on a poorly prepared surface.
Preparatory work consist in cleaning the surface of the body, removing attachments, removal of old paintwork (in case of need) and rust, as well as degreasing.
We remove the cross-cutting corrosion of the car body
When preparing for the color of automotive parts, we often encounter with sufficiently strong corrosion foci. I am asked many times on the forum and in personal letters, how to deal with a strong corrosion, which has already significantly driven metal sometimes even through. Indeed, with body repair, there are places on the elements of the car, like the bottom of the doors, wheel arches as well as others who are inherent only in a certain brand, and this is not uncommon, especially if the car has already traveled a lot of enough in our cheese climate.
PDR technology - repair dents without painting
According to statistics, about 30 percent of vehicles have visible injuries on the body, while the car paint coating is not broken. This may be like all sorts of small dents, and sufficiently serious damage to the body.
In this case, instead of a full body repair comes to the rescue PDR technology - repairing dents without painting. We read the details ...
The author of the presented twenty-minute video tries at once three ways to repair the body of the car with their own hands. For his experiment, he chose the left back wing of his own car, which still shall be replaced and pissed by a hammer on it in three different places. Celers turned out to be different and in diameter and in depth, as required.
And then, in front of the audience, the author is trying to correct these problems in three different ways, simultaneously explaining what and how he does, which tool uses and what power must be applied to get if not the optimal result, then at least close to perfection. Something turned out of him, but by some method he remained very pleased. However, his experience will be useful to all motorists who want to ask repairs to their steel horse on their own. Watch the video "body repair of the car do-it-yourself" in good quality 720 HD. All materials 2017 and 2018 are contained on YouTube.com and are available on our website without registration.
The cost of restorative repair of the car, even after a small accident or other damaging factors, is quite high. But after all, it seems that there is nothing particularly difficult in these works. If there is a desire, time and relevant resources, then repair the body of the car with your own hands is performed quite under power. We will describe the technology in stages.
Defektovka
First of all, it is necessary to determine the amount of work done, and for this car must be washed and thoroughly examine.
Geometry
First you need to make sure the integrity of the spatial geometry of the body.
Control is performed by measuring distances between checkpoints. If there is no information in direct points, then you can focus on the visible strength structure. The distances between the elements of the mounting suspension, the power unit must be symmetrical.
If the geometry suffered, then the restoration of the car body is possible, but it is extremely difficult. The fact is that for this purpose you need special equipment, almost a whole stand that allows you to pull the body in an arbitrary direction. This equipment is not like.
Of course, you can try to use healthy tools, such as various stretch marks and jacks, but it is rather difficult to restore the car body with such a means.
Because if there is no possibility to use the appropriate stand, then take it, no sense - repair in the service will be cheaper.
Corrosion
It should be carefully taken to the stains of rust. Through corrosion should also not "pass by." If there is only a rusty stain on the paint, then this does not mean that the base has not rotted - under the paint metal may not be. All these places need to be checked (the simplest way - tapping, the sound will become clear).
Small dents
Often, the repair of the body of the car is started only due to the presence of many small damage. Although the control of other items does not cancel.
On the other hand, if the deformations are small, without pulling out the metal and breaks, and even where there is no ribbon ride, they can be corrected without resorting to the subsequent painting. This is achieved by restoring the original form by mechanical way with the preservation of the paint layer, but it is complex and long-term operation.
When the welding or replacement of the part is required, then without painting no longer do. But you can act more simple methods, and the result will also make it possible to do without spatle. Although if it is not fundamentally, it is possible to simplify the procedure, but closer to painting.
Repairs
If the repair of the car body requires the restoration of geometry, then the above reasons to make it independently pretty difficult to make it. The process, if briefly, consists of pulling in three dimensional space a predetermined point of the body. For this, it is necessary not only to "calculate" this point geometrically, but also to predict the behavior of the body when extracting, and then experience is required.
Therefore, we consider a simpler and more frequently required type of repair.
Replacing body elements and welding
First we replace the elements of the body kit, which is easier and cheaper to replace, rather than restore. It can be doors, hood, wings, trunk lid, etc.
Next, eliminate the effects of corrosion. Through defects are cut completely to "live metal", where the fresh material is then welded. Where corrosion did not reach such a swing - simply clean the surface to metal.
Small demerican straightening
Body repair of the body of the car, almost never costs without work to eliminate deformations in the form of dents. And, most often, it is dents, because The case of the machine is convex itself, and the external effects of excessive force create deformations precisely in the form of dents inward.
Very small defects (shallow dents, on a flat surface) fix the easiest. They are even called "clams", due to the characteristic behavior during recovery - it is enough to heat or mechanically affect on the reverse side, they are returned with characteristic cotton to its original state.
Repair already more serious damage requires full removal of paintwork. For this purpose, it is convenient to use a grinding machine with an appropriate nozzle. The main thing is not to overheat the metal (do not bring before the science), otherwise it changes the properties.
Another thing is when the metal from the perimeter stretched out the metal strongly (deep dent). Here it is necessary to "hold" him back so that he returned to the initial mind. Those. Impact, it is necessary since the perimeter, smoothly outlining the surface to the original form. For this purpose, a small anvil and rubber cosyan (or a wooden hammer) will be required. It is undesirable to use the iron hammer, because it produces strains of tin.
The anvil is applied to the outer edge of dents, and from the inside, using the image, the metal is returned to its "legitimate" place.
Restoration of strong deformations
When the metal is pulled too much, the previous method will straighten it quite difficult. But it will also be necessary to remove the paintwork. In addition, the body's body repair of this type will require the presence of an industrial hair dryer and / or dot welding machine with various graphite electrodes.
The process itself is similar to the previous one - it is necessary to strain a dent from the perimeter, approaching the center. It is only not a mile and anvil, but the point heating of the metal, and then the mechanical impact. In the process of heating, it becomes more plastic and supple. The degree of heating is selected by an experienced way.
If the industrial hairdryer is used, then there are no difficulties here. However, when point welding applies - attention is necessary, otherwise you can burn metal through. The form of the electrode depends on the shape of the dent itself - round is convenient to correct the round electrode, and the long - wide.
Other methods
To restore the form, you need to get to the part on the other side, but it can be either impossible or too hard. In this case, you can try to straighten the dent completely outside.
For this, weld (more precisely grab) the welding electrode to the place of the metal surface, which must be pulled out at the moment. Next, using either a special snap, or the back hammers are pulled out the metal. After that, the electrode is packed, and the surface in the place of welding is grouped. This is a fairly simple and effective method of recovery of the form, if you are repairing the car body with your own hands, because only the welding machine is required from expensive equipment. Reverse hammer can be even made independently.
Another recovery method is a metal attack in a dent. In this embodiment, the deformation is not corrected, simply in the resulting "pit" is attacked by a special solder. With this method, the surface can be removed almost perfect, so that the specialized device for measuring the distance to metal (paint thickness) will not show traces of repair.
For the attack it will be necessary for solder, flux (with acid) and heater (powerful soldering iron). The surface is thoroughly cleaned, after which the mud is made (the small layer of solder is applied). Further, the whole required volume is gradually pressed, the main thing is that it was enough. At the end of the soldering, the surface must be rinsed thoroughly, because Flux is chemically active, which can lead to corrosion.
Of course, the surface is ideal not to do - the corresponding mechanical processing will be required. Next, the excess are mechanically stepping, until the correct form is obtained. After polishing, the perfect surface is already obtained by the results.
Repair and restoration of the car body with such a method in the garage conditions is very simple. At the same time, it is not even necessary to disassemble anything. True painting will still need. Small irregularities can be simply aligned with putty, you can and are large, but it is unreliable. However, this is the topic of another article.
The body of a modern car is a complex design that performs many important functions. Its repair is the opposite side of the medal of importance and functionality. It is complex and time consuming.
Conditional body repair You can divide into two stages. The first is, the elimination of dents, the replacement of non-repaired elements. Second -.
Special attention should be paid to the restoration of geometry and stiffness hidden from the bottom of the body. These items are responsible for the safety and running characteristics of the car. All suspension elements are attached to it.
When saving on materials and tools for the repair of the body, it is necessary to remember that such savings can affect the quality of the body repair and be a consequence of common errors. It is about not to allow such mistakes to be familiar with the main features.
Features of body repair
To know all the features that are taken into account when understanding what to talk to the master before passing the car to repair and what to pay attention to when receiving a repaired car, we offer
Welding elements by conventional electrodes
Connect the body elements by electronic welding is difficult, but real. In this case, the quality of such a compound is very low.
Violation of thermal regime
If you do not get cooling the metal during welding, then it is possible to displace the body that will have to apply. In this case, such defects can not always be fixed with putty.
Replacing parts in strict sequence
The first thing is to replace the doors, then the wings and thresholds are exhibited. Only so you can avoid the formation of gaps.
Painting not in color
This often happens if one body part is painted without a smooth transition to another. Even if the paint is selected accurately with the original, then the old paint on the body has changes in the shade, which is associated with burnout in the sun and other environmental factors.
Shrinkage
Appear with poor quality and insufficient drying. Usually manifest after repair when the car stands in the sun. Usually you have to re-polish the places of putty.
Shagreen
This is the relief of applied paint. After painting, it is usually shagged on the body, but it is cleaned with polishing. But it happens that the polishing does not remove. Usually, the defect occurs with improper paint, at high temperature in the chamber, viscous paint.
Dust in paint
Usually occurs if you paint the car is not in a special chamber. But at the flushing in a dirty chamber also takes place.
Craterics
Deetensions from silicone hit, which needed to cut the special knife.
Filled lacquer
It appears if you work the grinding at high speed or to grind the same place for too long, without giving cooling the lacquer.
Manifestation of rust
If the welding seams are poorly cleaned and brands, then rust may occur in these places, which manifests itself through a paint coating.
Performing body repair car In particular, welding works, it is necessary to use semi-automatic or argon welding for welding. With the help of such welding, metal with a thickness of up to 1 mm and eliminates the possibility of burning body elements.
Body damage is light, medium or heavy. Richtovka usually does not require special skills and when using professional tools and materials will be able to die. Only certain difficulties and need for skills may occur during non-rich work after medium and complex body damage.
With the need of repair with more than 70% of the body, it will be cheaper to buy a new car, do not do body repairAnd old to sell on parts.
Paint car needs fresh paint. Soil will help you to reveal irregularities and sharpen them with finishing putty. You can only paint after complete drying of putty and cheap.
For painting, use a special paintopult. Keep paint should in special camera conditions without direct sunlight. Polishing is allowed only after a complete drying of the LCP.
