Anticorrosion treatment of a car: what it is and how it is done

Corrosion is the first enemy of the car. All car owners sooner or later face this problem. Prevention is crucial, and anti-corrosion treatment of the car comes to the rescue. It consists in applying special protective compositions to metal surfaces. This can be done on your own or go to a car service.

Causes of corrosion on the car

On a new car after three years, defects can be observed. This is entirely the fault of manufacturers who use low-quality metal for the production of the body. The oxidation process can be slowed down by adding special additives to the alloy.

In some cases, it is regrettable to recognize that the composition of the metal includes components that accelerate the destructive process. Even the fact that the machine stands in a dry, ventilated room will not play a role.

Causes of the appearance of corrosion on the car body:

• Humid climate and frequent precipitation.
• Fluctuations in air temperature.
• Poor road surface.
• Salt and chemical reagents.
• Tuning elements.

Composition of anti-corrosion agents

Protect the metal is possible with the use of various materials. Most often such coatings are used against corrosion:

• Liquid plastic.
• PVC.
• Bitumen mastic.
• Compositions containing paraffin and wax.

As for plastic, it performs the function of additional protection, since its layer does not have high wear resistance. PVC lasts much longer and preserves the integrity of the surface. It is favored by manufacturing plants. Bitumen mastic lasts a long time, protects and preserves the metal. Paraffin dries instantly and forms a strong elastic film. It retains its properties for a long time. It is important that the anti-corrosion coating does not violate the vibroacoustic properties of the body and is applied easily, including in the garage.

Whether it is necessary to treat a new car from corrosion

Often owners of new cars do not think about the prevention of corrosion in principle. Indeed, the primary treatment against destruction is performed by the manufacturer, but usually this is not enough, so the consultation of a specialist will not be superfluous.

How often to treat the car from corrosion

If the car is more than three years old, you need to find a reliable car service, agree on the choice of material, agree on the cost. The procedure is resorted to every year or, if the condition of the body allows, once every two years. It is necessary to regularly take care of drain holes, where condensation accumulates. Such design elements are in the rear arches, doors, sills. If it is not possible to monitor this independently, you can contact a service center.

Rules of anti-corrosion treatment

Before proceeding to the procedure, all attachments are removed. The car is thoroughly washed and special attention is paid to the bottom. Areas covered with a layer of oil are degreased. For bitumen and rubber mastic, the base is primed beforehand.

Then drying follows, as a wet base cannot be treated. Anticorrosive compositions are produced in the form of aerosols and liquids. In the latter case, you will need a brush, trowel and roller. A compressor will speed up the work.

Processing is carried out in a warm room. The temperature should be above 15 degrees. Layer after layer is applied 3-4 times, and the next one is put after the previous one dries.

After treatment it is necessary to let the car stand for at least a day. If there is a need to travel, it will be necessary to travel at low speed and on roads where there is no risk of damage to the body by gravel and sand.
