The better to process the bottom of the car

Water on the bottom of the car is not as bad asVarious aggressive mixtures with which the roads are poured for the sake of protection from ice. Such compositions quite strongly activate the processes of formation of rust. Corrosion can lead to the occurrence on the body of serious damages - up to through holes. The treatment of the bottom of vehicles is a necessary measure in order to protect the metal from the formation of rust. The car will serve for a long time and regularly, if timely carry out such processing.

The better to process the bottom of the car

Modern cars of foreign manufacturequite a long time will be able to do without special treatment. Domestic models should be processed immediately after purchase. Used cars need regular and high-grade anti-corrosion treatment of the bottom.

Types of protective agents against corrosion

Means for protection against corrosion of metal can be divided into two types:

  • passive;
  • active.

Passive form of protective means against rust implies that a protective layer will be formed on the surface of the car body. This protective film and will separate the body from the effects of moisture.

The composition of such tools are not includedcomponents that prevent the occurrence of corrosion. They just protect the body with a film that forms on the body of the car. The thickness of this film is not very large. As a rule, 2-3 mm, not more. The application of a thicker layer of the substance is unreasonable. Such tools are almost always made on the basis of resins, mastics, bitumen or elastomers.

Active means for body protection not onlyform a protective film, but still fight against all manifestations of corrosion. Special agents convert the appearance of rust to a stable phosphate compound. Such agents include orthophosphoric acid, which is considered to be an ideal corrosion inhibitor.

As for the consistency of the funds, they canbe as fairly viscous (for example, different mastics), and be in a liquid form, and also have the property of being sprayed under pressure. Both viscous and liquid formulations perform their task approximately equally. But there are differences in the method of application.

Liquid sprayable formulations can easilypenetrate anywhere. After all, when spraying a light mist is formed from the small drops of the agent. Still complete with a spray is a long thin nozzle, which you can reach the most inaccessible places.

Viscous anticorrosive agents are difficult to cover closed cavities. Such compositions are usually applied manually using a wide brush.

Anticorrosion for the bottom of the car

For the treatment of the external sides of arches and bottoms, shale mastic is used. After its application, a bitumen film is formed. This provides almost complete waterproofing of the body.

Bottom and wheel arches with internal and externalthe sides can be treated with rubber bituminous mastic. In addition to protection against corrosion, rubber bituminous mastic protects against gravel impacts. Also the product withstands severe frosts.

Mastic based on bitumen and rubber protects the exterior and interior parts of the body, including unpainted surfaces - thresholds, arches, trunk, etc.

The most popular tool for combatingcorrosion - movil. It reliably protects all parts of the car body, including the joints and joints. Movil is well distributed over the surface, quickly forms a waxy layer, expelling moisture.

In addition to anticorrosions, threshold automotive preservatives can be used. They will not only protect the car's thresholds, but also protect doors, racks and other parts from aggressive anti-ice coatings.

Before using anticorrosive agentsyou need to properly prepare the surface of the body to apply anticorrosion. When applying the product, an obligatory condition is observance of the recommended temperature and time regime. If these parameters are met, the anti-corrosion treatment of the bottom of the car will be most effective.
