Removal of rust from the body of the car: stages of work, means and recommendations

Every car owner faces corrosion, many of them are concerned about removing rust from the car's body. There are several ways to combat this problem. They all have different efficiencies. Naturally, it is best to contact a specialized service. However, if this is not possible, then a war with rust can be waged on its own. So, let's look at how to eliminate corrosion in many ways.

Rust: types, causes

This is called one of the types of corrosion. To be more precise, it is already a product of the chemical process. In fact, it is iron oxide, which appears as a result of the destruction of the metal structure. Corrosion can be wet and dry. The latter does not arise at all without any moisture. Steel and iron can just fade. If the affected area is also exposed to moisture, then wet corrosion starts. It will even more intensively hit the body parts. That is why the removal of rust from the body of the car must be done as quickly as possible. There are several situations in which car owners are acting wrong, which leads to sad consequences.

Temperature differences

Everyone faced a situation where, after a trip in the evening, a cold car that was standing on the street was driven into a heated garage or box. And it's good if there is a good ventilation system in the room where the car will be stored. If it does not, then condensate will form on the surface of the body. This will increase the humidity, which is the cause of intense corrosion.

Snow on the bottom of the car

This is one of the situations when mistakes or ignorance lead to unpleasant consequences. So, if in the winter the driver does not clean the bottom of the machine from the snow layer, then corrosion will not take long. With frequent winter driving you need to constantly remove snow and clean the bottom. Otherwise, the motorist is waiting for the removal of rust from the body of the car.

Regular washing in summer

During this period it is important to wash the car frequently so that the mud does not have its destructive effect. After the rain, you must carefully dry the body, but some close the car after washing immediately to the garage. It is not right.

The most common corrosion damage

So, rust can be different, and depending on where the affected area is located, it is divided into specific species. Below we will consider each of them.

Cosmetic

It occurs where different lining from other non-metallic materials is installed. Often foci of rust appear under the headlights, lanterns, radiator grilles, under moldings. If chemical processes are removed immediately, using a means to remove rust from the body of the car, then there is no danger. But if you run it, then the corrosion will move to the next level.

Podplenochny

This type of corrosion is formed not on the surfaces of metal parts, but under the paint and varnish coating. This rust looks like small foci. The main disadvantage of such corrosion is that it is not always possible to see obvious foci.

Occasionally, there is a swelling of the paint. Another serious disadvantage is that such rust does not just grow and then diverges across the entire area of the element, but also deeply affects the metal. Often in neglected cases, even a qualitative rust removal from the car body can be a futile process.

Anyway, in the course of time, a through hole will appear. Only welding works will help here.

Cross-section corrosion

This is the last of the stages. It is because of her that huge holes appear in the body. But faster through is only point rust. These are small small dots. They grow not on the surface, but deep.

Tool for removing foci

Now, when almost everything is known about corrosion, it is necessary to find out what are the ways to remove rust from the car body. But first you need to talk about the tools that come in handy in the works. Working with metal requires certain tools and consumables. In this case, it may be justified to purchase professional means of autochemistry. You will also need a grinder. Still need to purchase a sandblaster. If this is not possible, then you will have to settle for metal brushes and sandpaper. Of the consumable chemicals, you need any liquid for degreasing, a liquid for removing rust from the body of the car, car putty, anticorrosive soils.

Methods of warfare with rust

In order to combat corrosion, it is necessary to find its foci of origin. She can hide in quite unexpected and, most importantly, difficult places. Experts recommend thoroughly wash and dry the machine, and only after that look for foci. On how far the body is launched, it is necessary to build on the selection of a suitable method.

Sandblasting

Removal of rust from the body of the car is very effective due to the fact that even small and small pores are captured in the process. In this case, the integrity of the metal around the source is not violated. If you use a machine that has the function of reverse circulation, then you will not have to collect sand. But not always such an apparatus can be rented. The purchase of equipment due to its high cost can be unjustified. In general, sandblasting perfectly fulfills and cleans the most hard-to-reach places on the body and bottom.

Grinding

A special apparatus is necessary for this method. The process is pretty fast. The metal will be stripped literally to shine. But there is a drawback - together with corrosion, a layer of normal metal that is depleted as a result of corrosion processes will be removed.

Grinding by hand

The essence of this method is the same as in the case of a typewriter. The difference here is that everything has to be done on its own. The work will use a metal brush, sandpaper of various granularity. The only advantage that this rust removal from the car body has is the price. All that is needed can be purchased at any hardware store inexpensively. Also, by hand grinding, it is possible to clean out places in which the machine simply does not fall. As practice shows, the cost of all works is from 1 to 3 thousand rubles.

Chemical method

Rust foci must be treated with special aerosol agents. They also apply a zinc converter. Further, all these compositions are washed off with ordinary water, and clean places are dried and treated with anticorrosive agents. On sale there is a primer-converter. But the downside is that after applying the fluids you can not paint the affected area. The paint just will not hold. As a result of the interaction of the converter with rust, a special structure is formed that behaves like a primer.

Electrochemical removal of rust from the car body

This method involves redox reactions in damaged areas. The process takes place in the electrolytic solution under the influence of current. It sounds difficult, but it's only at first glance. In fact, this is the simplest method. There are already ready-made sets - if you carefully read the instructions, then everyone will be able to understand the process. Among the advantages of this method is the complete removal of foci of corrosion on the affected surface. Applying zinc, safety for the car's LKP, quick result, simplicity. The downside is that this technology is not effective for working with large areas and through corrosion. Here it is necessary to use additional means.

Corrosion control: basic stages

Consider how the removal of rust from the body of the car (stages of work) is performed. To perform a mechanical struggle, you will need to thoroughly wash the car. Then, using a grinder or sandpaper, the rusted element is cleaned to the metal. Then cleaned in this way the surface is thoroughly degreased, and then processed by a converter. And finally, the place is covered with enamels in case of minor damage or shpaklyuetsya and painted, if this is a major damage. To work electrochemically, you need to purchase a kit. It is designed for processing 1 sq.m.

Summary

As you can see, it's possible to fight rust, and it's quite effective. The main thing is to choose the right method.
