Qu'est-ce qu'un traitement antirouille

What is a rust proofing treatment?

Apply a rust-proofing treatment to a vehicle’s body to prevent corrosion from forming or spreading if it has already started to form.

Rust is a natural reaction resulting from the oxidation of iron in contact with air and water. This reaction accelerates and worsens in Canadian winter; the rain, snow and road salt covering the streets contribute to vehicle corrosion and in short, without protection, the metal surfaces on your vehicle will be damaged, regardless of the composition of metal used. This is why automobiles, even new ones, are at risk of being affected by corrosion. Damage to modern automobiles through rusting is a natural phenomenon that cannot be avoided. However, it can be prevented or slowed down by a rust-proofing treatment.

What is Rustproofing?

A rust proofing treatment is a product that is applied on vehicle’s body metals to prevent corrosion and trapped moisture from forming or spreading rust if it has already started to form. This chemical process is used to extend the vehicle’s lifespan while maintaining its value by making it corrosion resistant. It creates a rustproofing barrier against moisture and small abrasives found on roads. The rust protection is applied to the areas that are most likely to be affected by rust such as the bottom of doors, fenders, hood, paint chips and smaller rust spots. If you do not have your car treated, rust could quickly attack the steel and damage the paint, body, and more important parts of your car.

Different Methods of Rust Protection

There are two main types of rust proofing options available on the market: grease based rust proofing treatment and oil-based rust proofing treatment. We will explain the difference between the two, in terms of application and effectiveness. Whichever treatment you choose, it is important to get professional help to make sure the product is applied properly and covers all risk areas.


Rustproofing: Grease with added wax

A one-time application for long-lasting protection against corrosion

The grease-based treatment offers good coverage and little compromise. It is a treatment that is supposed to last for the life of the vehicle. However, no treatment can resist rust for more than 10 years without a second application.

The grease-based treatment with the addition of wax provides excellent coverage. The addition of an anti-corrosion wax extends the treatment life by two to three years. It provides superior rust resistance by forming a protective barrier for greater durability against water and moisture. The process of applying the product can take a few hours and it adheres to surfaces a little better than oil. This treatment is only carried out on new or very recent vehicles.


Oil and paraffin

Cheap and effective annual rust proofing

The oil-based rust proofing treatment is the most popular treatment. Compared to other types of treatment, it is the less expensive choice. It is very effective, but requires an annual reapplication. Since the oil tends to run, paraffin is added to it. On contact with air, it thickens to prevent any dripping or smearing, providing a permanent shield from the elements.

The fluidity of the anti-rust chemicals allows treatment access to hidden joints and corners and forms a barrier resistant to water and abrasives found on roads. The application process takes about an hour, longer for non-standard vehicles. The product spreads through the entire body of the car and protects the parts most at risk of being affected by rust.


How often is it recommended to rustproof your car?

In order to provide optimal corrosion protection for your vehicle, it is recommended that you rustproof your car every year. However, the frequency may vary depending on the type of treatment you have chosen for your vehicle. For a grease treatment with wax added, you will probably need to repeat the treatment after 2 or 3 years. You can touch up some areas of the vehicle during your annual maintenance.

For an oil-based treatment, an annual application is recommended. It is not always necessary, as some vehicles are more resistant to rust than others. However, it is better not to take any risk and spend a small amount of money each year, rather than having to pay important fees to repair or repaint your car.


How is the rust-proofing treatment applied?

Depending on the type of treatment to be applied, the application can take between one and five hours. Here are the basic steps that need to be followed to apply a rust-proofing treatment:

1. Vehicle preparation

It is mandatory to clean the vehicle of any road dirt before applying the treatment. Some professional workshops are already equipped to offer this service. In case of rain or snow, the car is washed and then dried to ensure the product adheres properly.

2. Application of a rust inhibitor

Once protection is applied to areas that should not be touched by the product, spray guns are used to spray the rustproofing compounds uniformly and accurately. The areas where the treatment is applied are the body panels, hood, front and rear fenders, sliding doors, trunk lid, sills, as well as to the entire underside of the vehicle (including any spot welds, folds or seams in the metal), which is known as an undercoating. Unseen corrosion can often be fatal for a car, so special care must be taken to properly protect rust traps, small nooks and crannies that can collect road dirt and water.

3. Washing the vehicle

The vehicle is then washed to remove any product residue. It is then checked one last time to make sure all areas are covered. A sticker is provided to the owner certifying that the vehicle is protected against rust.


Do I need to clean my car before applying a rust-proofing treatment?

Not only is it necessary to thoroughly clean the vehicle before applying the treatment, but you also need to do a good underbody cleaning. Some shops that apply rust proofing require the vehicle to be properly cleaned. It should be noted that the application of an oil or grease-based rust proofing product on a dusty or muddy surface is obviously not very effective, and does not give lasting results.


When to have your vehicle treated against rust?

It is important for vehicle owners to know when to get a rust-proofing and undercoating treatment for their car. Determining the right time maximizes the effectiveness of the treatment. Generally, it is recommended to have your car treated during spring or summer to provide the best defense against rust because these two seasons have a dry environment. The rust inhibitor will therefore act better on the car’s metal thanks to the heat offering optimal protection. The heat facilitates the penetration of the product applied on the different parts and prolongs the effectiveness of the treatment.

You can also have your vehicle treated in the winter, but the process will take much longer than usual. The vehicle must be completely dry before application and after for the product to adhere well.

How to choose a rust-proofing treatment?

It can be hard to pick between oil and grease. However, annual treatments are recommended no matter what because there are areas in the vehicle such as the inside of the wheel arches, the vehicle underside and the doors bottom that require yearly inspections and maintenance. It prevents structural rust from touching sensitive areas of the vehicle.

There is no such thing as permanent rust protection. Indeed, the car underside and the wheel arches are subject to mechanical abrasion that no treatment can resist. An annual treatment is therefore necessary to minimize the damage to vehicles cause by corrosive materials.

Either way, remember that the quality of the application is extremely important. It requires precision and expertise, so preferably choose a specialized company. Professionals know the vehicle’s weak points, they have the tools to do a good job and they can help you choose the best treatment for your vehicle.


What are the benefits of rustproofing ?

If you want to keep your car in good condition for a long time, it is important to have your car treated. A rust proofing treatment is one of the most effective solutions to prevent corrosion. Here are the two main reasons why you should rustproof your car.
