Car corrosion is an inevitable process that gradually destroys the metal parts of the body. This process can begin at any point in a car’s life cycle and cause significant problems for the owner. In this article, we will look at why corrosion occurs, which body parts are most susceptible to it, how to delay the corrosion process, and what corrosion control methods are available to car owners.
Causes of corrosion
Corrosion can be caused by a number of factors such as exposure to salt on roads in winter, moisture, acid rain, atmospheric pollution, etc. Corrosion develops when the metal comes into contact with the environment and the metal oxidizes.
Types of corrosion control
Two main methods are available for corrosion control: mechanical and chemical.
- Mechanical way
The mechanical method is the simplest and cheapest way to remove corrosion. It consists in grinding the damaged surface until it is completely cleaned of corrosion. But this method has some limitations, as rough sanding of the surface can cause scratches and other damage, which can damage the paint on the body.
- Chemical method
The chemical method of removing corrosion is a more technologically advanced and effective way to combat corrosion. It consists in the use of chemicals that dissolve corrosion without damaging the metal surface. This method also helps protect the surface from further corrosion.
Removing Corrosion From Car Body
If there is already corrosion on the car body, then it must be removed to avoid further destruction of the metal. To do this, you can use both mechanical and chemical methods.
The mechanical method of removing corrosion is the process of grinding the surface until the corrosion is completely removed. For this, special tools are used, such as grinders, sandpaper of different grits, glass fibers, etc. This method is very effective but can damage the paint and finish on the car body.
Chemical corrosion removal is the process of using chemical solutions to remove corrosion. This method is safer for the car’s surface and does not damage the paint and finish. Chemical solutions contain harsh chemicals such as phosphoric acid, oxalic acid, sulfuric acid, and others.
Why Corrosion Is Dangerous
Corrosion can lead to serious problems with the car. It can damage the car body and parts such as doors, hood, roof, fenders, etc. In addition, corrosion can lead to deterioration in the aesthetic characteristics of the car, as it leads to rust on the body.
Which Body Parts Are Most Corrosive?
Some car body parts are more prone to corrosion than others. For example, wheel arches, sills, bumpers, underbody and other places that are closer to the ground and are more exposed to road salts and dirt.
How to Remove Corrosion From a Car
If there is already corrosion on the car body, then it can be removed using the mechanical or chemical methods described above. After removing the corrosion, it is necessary to paint the surface of the body to protect the metal from further corrosion.
How To Delay Corrosion Process
There are several ways that can help delay the corrosion process and protect your car from possible problems. Here are some of them:
- Regular washing and cleaning of the car, especially after driving on salty roads or in winter, when salts and chemical solutions are used to clear snow and ice from roads.
- Coating the car body with a protective coating or wax that protects the metal from external factors.
- Checking the car for hidden corrosion and removing it at the first sign.
- Regular vehicle maintenance, including changing oil, filters and other fluids, to prevent corrosion of internal parts.
- The use of anti-corrosion agents when replacing parts or repairing a car.
Popular Rust Removers
There are many rust removal products on the market. Here are some of them:
- Acidic solutions based on phosphoric acid or sulfuric acid.
- Special pastes and liquids for removing corrosion.
- Sandpaper of different grits and other tools for mechanical removal of corrosion.
- An electrolytic method that uses electric current to remove corrosion.
However, before using any corrosion remover, you must ensure that it is safe and effective for the specific type of corrosion and vehicle surface.
In conclusion, we can say that the fight against corrosion of the car is an important task to maintain its condition and extend its life. Regular maintenance and protection of the car body will help prevent potential corrosion problems. If corrosion is already on the body, then it must be removed and repaired as soon as possible.
