Any car ages over time, because metal tends to wear out. Of course, owners are trying to extend the life of their equipment. One of these methods is the anti-corrosion treatment of the bottom of the machine. You can make it in a car service or do it yourself.

Types of corrosion

Metal corrosion is an inevitable process. Over time, rust spots appear on the car body, which gradually turn into holes. Because of them, the strength of the structure is reduced, and distortions can occur. This situation is very dangerous and can cause an accident. To avoid this, anti-corrosion treatment of the bottom is applied.

There are several types of metal corrosion in a car:

• Gas (the muffler is destroyed, the chamfers of the valves in the combustion chamber, the exhaust pipe).
• Corrosion in the electrolyte (moisture accumulation areas).
• In non-electrolyte (destruction of oil and fuel systems).
• Contactcorrosion (places where different metals come into contact).
• Slotted (moisture accumulating in the gaps leads to the decay of the metal).
• Stress corrosion (destruction of high voltage surfaces).
• When rubbing.
• Atmospheric corrosion (destruction of metal under the influence of weather conditions during storage and operation of the car).
• Mechanical (damage to the bottom of the car from crushed stone and pebbles).

The most corroded parts of a car

Most often, the bottom and thresholds of the car suffer from corrosion. Driving off-road, on high grass leads to the erasure of the protective layer. Small stones hit the lower part of the body, creating damage on the metal, which eventually begins to rust. Therefore, it is so important to do repairs on time, which should include anti-corrosion treatment of the bottom of the car.

Pipelines, cross members and frames also suffer from metal decay. If you do not treat them with anti-corrosion agents, they will become unusable very quickly.

Rust eats into brake systems and spring brackets. It can cause holes in doors, fenders and bumpers.

In general, all metal parts need maintenance. Don't forget about it. If anti-corrosion treatment is not carried out, parts may wear out, and the only way out will be to replace them.

Anti-corrosion agents

Today, the market offers quite a lot of anti-corrosion agents. Among them, mastics for bottom processing, all kinds of varnishes and pastes, which contribute to the restoration of the body coating, are very popular. These materials effectively protect the metal from various types of negative influences.

Anti-corrosion treatment of the bottom of a car is often done by the owner himself. Below we will tell you how to properly carry out the work. The choice of anti-corrosion agent is also important. It is worth paying attention to the fact that it must have the following qualities:

• Environmentally friendly (products must be safe for the human body and the environment).
• Abrasion resistance.
• Frost resistant.
• Plasticity (transfer deformation of car parts while driving).

Means for external and internal processing

Anti-corrosion treatment of the bottom is one of the important processes, but do not forget that internal parts are also subject to decay. Let's talk about which products are best used for external processing, and which ones should be used to cover internal parts.

External parts include: bottom, wheel arches and sills. They are constantly in contact with stones and sand flying from under the wheels of the car. For their processing, it is recommended to use plastic products, such as bituminous resins and mastic, characterized by anti-noise qualities.

Internal metal parts of the body are treated with compounds that have wax or oilbasis. They have a liquid consistency and easily fill the smallest cracks, preventing them from growing.

Selecting a service for anti-corrosion

Anti-corrosion treatment of a car in a service is considered more effective. This is due to the fact that an ordinary motorist cannot detect all body defects and select the appropriate anti-corrosion agents correctly. In addition, car service specialists will save you from the need to spend your own time and effort.

Finding a suitable service station and finding out the price list is quite easy. For example, anti-corrosion treatment of the bottom in St. Petersburg is carried out in many services throughout the city, so you can easily choose the right one.

Arriving at a specialized service, you should clarify with the masters the main details of the work, namely:

• What anti-corrosion agents do they use.
• How to remove existing rust.
• How coatings are applied.

If the master speaks to you confidently and is fluent in the details, then you can trust the service and not be afraid for your car.

Steps of work

Regardless of whether you do anti-corrosion treatment yourself or contact a specialized service, the work consists of several stages:

• First of all, the car should be thoroughly washed with detergents. The car needs to be raised to clean not only the body, but also the bottom.
• Then you need to dry all the details well. You can speed up the process by blowing hot air.
• When the machine is dry, it should be inspected for defects. Detected cracks, scratches and chips must be processed.
• Only after that you can start processing with anti-corrosion agents.

In the service, these actions are performed by professionals. If you are going to do the processing yourself, you will need a lot of time, but the result is worth it.

Do-it-yourself anti-corrosion treatment of the bottom

First, the machine is installed on the lift. The wheels need to be removed as they do not need to be machined.

The bottom should be washed with a strong pressure of hot water. This must be done carefully to remove all dirt.

After that, you need to get rid of the rust. It is better to use sandpaper or a grinder for this.

When all the rust has been removed, the car should be dried by blowing warm air on it with a building hair dryer, otherwise the anti-corrosion treatment of the underbody will be ineffective.

Next, you need to carry out a thorough troubleshooting of the bottom, which consists in getting rid of cracks and holes with the help of anticorrosion.

After that, you can put the wheels on the car and lower it. Driving during the day is not recommended. Let it stand for the coating to set.

How to properly apply anti-corrosion coating

It depends on how correctly you treat the car with anti-corrosionservice life of the equipment. In order to avoid difficulties in the process of work, you should know in advance the features of applying various means.

Liquid products are best applied with an airless spray gun. It costs a lot. There are also special guns for anti-corrosion treatment. In hard-to-reach places, flexible nozzles are used.

Can be processed with a brush. You need to work with it carefully, without gaining a lot of money at a time. All parts should be thoroughly lubricated. In order not to stain the drive belts and the generator, it is recommended to cover them with a film.

Safety rules

Before handling the car, you should study the safety rules to avoid accidents.

• The vehicle should be handled in a well-ventilated area.
• It is necessary to observe fire safety rules when spraying drugs. Flammable substances should not be left exposed to sunlight.
• It is necessary to carry out work at an air temperature not higher than 30 ͦС. For example, anti-corrosion treatment of the bottom in Lipetsk, as in other cities, in hot weather should be carried out with extreme caution.
• If the product gets on unprotected areas of the skin, you need to wash them with soap. If the anticorrosive gets into the eyes, they are washed with running water for 15 minutes.
• Funds and tools must not be left unattended.

Now you know how anti-corrosion treatment of the bottom of the car is carried out by yourhands. Work should only be started if you have the skills to work with the machine and having free time. Otherwise, it is better to contact a car service.
