It generally takes between 30 to 45 minutes. In times of high production, product application time can be reduced by the number of employees working simultaneously on your vehicle. During winter, it takes approximately an hour to allow us to de-ice and dry your vehicle.

Our climate is very harsh and rust proofing products lose their effectiveness over time. The salt dumped on roads during winter, as well as sand and dust can damage the protective anticorrosion coating, which eventually leave certain parts of the vehicle unprotected. That’s why an annual treatment is required to provide complete ongoing protection.

Yes, as soon as possible. This will prevent the corrossion process from even starting.

Yes, as soon as possible. Even if your vehicle is a little rusty, our rust proofing treatment will greatly slow down the progression of existing rust and prevent new rust formation.

Yes. Humidity, drastic temperature changes and road chemicals will still favour rust on your vehicle if it is not protected. We recommend annual rust proofing protection, regardless of the number of kilometers driven each year.

Yes. Large industrial dryers allow us to completely dry your vehicle. It is important to dry your vehicle to facilitate the infiltration of our rust proofing product. After the treatment, rain will not remove our product because it is strongly bound to the metal and does not mix with water. Thus, it creates a barrier to water and moisture. Just try to wash your oily hands with water, oil does not leave, even when rubbing, you need soap.

It is not necessary. On the other hand, it is advisable to clean the underside and fenders of your vehicle, if it is unusually dirty (thick layer of mud, etc.).

Yes, we protect many electric and hybrid vehicles annually against rust. There is no contraindication against rust regarding our product with these types of vehicles. See our section on electric and hybrid vehicles.

Yes. We first proceed to a high pressure rinse to de-ice your vehicle. We then dry your vehicle with large industrial dryers. It is important to dry your vehicle to facilitate the infiltration of our rust proofing product.

Anytime is a good time. The treatment is effective for one year. We are equipped to treat your vehicle regardless of the temperature.

See section «Our treatment».

Our technicians drill access points in strategic locations (bottom of doors, rocker panels and rear fenders) only during the first treatment. These access points allow us to introduce the product to reach and protect hard-to-reach areas. Thus, we prevent rust from developing in enclosed areas. After the treatment, each access point is coated with our rust protection, then covered with a black plug.

Yes, free warranties are available for new and certain used vehicles.
The warranty for used vehicles is available only if your vehicle is in good condition, with less than three years of age and less than 60 000 km.
See our Warranty section.

Our rustproofing product can not remove existing rust, but it will slow its progression and prevent new rust from forming. If you need to have rust removed, we recommend contacting a body repair shop.

Yes, if there is fresh paint on your vehicle, you must wait at least a week before proceeding to your rust proofing treatment.

If you have an accident with your vehicle in the next few months following our treatment, we will treat the damaged parts again for free.
Please call us to inquire an appointment.

For rust to form, three things are needed: iron contained in metal, water and oxygen from the air. While oxygen is always present, steel does not rust when the air is dry. If steel sheds water quickly, the corrosion doesn’t have time to form, but if metal retains moisture, it rusts. In addition, when steel is subjected to physical stress, such as sudden temperature changes, vibrations, etc., vulnerable areas can form that make iron more likely to rust.

No. It first appears in a microscopic form, invisible to the naked eye. Furthermore, it’s important not to forget all the hidden areas of your vehicle where rust can develop without your knowledge: inside the doors and hood, rear fenders, frame, pillars, and rocker panels. It is therefore important to have your vehicle treated once a year to prevent any rust from developing.

There are elements that can accelerate the development of corrosion:

• Salt and calcium, which increase the conductivity of the water;
• Air pollution and acid rain are very corrosive. As well, our air contains many more gases than it did 50 years ago, like sulfur dioxide and nitrogen oxide. This is why our cars rust more than our grandparents’ vehicles did.
• Sudden temperature changes, especially when cool or cold weather becomes warm and humid.
• Actually, heat expands metal, which then allows the ambient or projected humidity to embed itself more easily into steel pores. Contrary to popular belief, metal rusts in hot weather, not in winter. However, winter prepares the ground for the forming of vehicle corrosion with snow, mud, salt and calcium, and especially when wheels throw these materials violently at the undercarriages of cars and trucks.

The assembly of a car or truck promotes the formation of rust. While it’s assembled, the parts of a vehicle suffer no less than 1500 folds and rivet points. This shaping damages the vehicle’s original rust proofing, which leads to the formation of rust. In addition, to offer their vehicles at a lower cost, manufacturers often use cheaper alloys that are lighter, but also more vulnerable to rust.

For these reasons, if you have just purchased a new vehicle we recommend that it be treated immediately , even if the manufacturer guarantees it against rust. The corrosion will have no chance to settle, and you will benefit from our warranty against rust.
A car has many concealed corners…where moisture still manages to settle! For example, this is true of the inside of doors or the hood, where water gets trapped without being able to evaporate. Fortunately, Metropolitan Rust Proofing treats these fragile areas and all others, like the rear fender, the doors and rocker panels.

During winter, the undercarriages of cars are frequently subjected to harsh attacks from sand, salt and calcium being thrown by the wheels. In addition to being rust accelerants, these materials can even damage the best rust proofing, even yours. Because of the climate we live in, it is important to treat your car once a year.
