Rust proofing treatment

Is there any danger for my vehicle’s electrical system?
No. Our product is safe for your electrical system, wires and all its electronic components. In fact, mineral oil (the base of our product) is used in Hydro-Quebec transformers to isolate electrical currents.

Can the manufacturer cancel my warranty?
No. It would be illegal in this case to cancel a warranty without proving an irrefutable cause and effect link.

How much experience does Metropolitan Rust Proofing have with EVs?
To date, we have treated more than 8,000 electric and hybrid vehicles, all makes combined.

I have read in articles that to properly treat an electric vehicle, it can take up to 3 to 4 hours of work. It is also said that it is imperative that no product be applied to the electrical module, or it could void the manufacturer’s warranty. How can you provide an effective and safe treatment in just a few minutes?
There is no rust protection sprayed on the electronic components as they are already protected from splashing water from the road. We only treat the vehicle body and it is in no way different from a standard vehicle body. Vehicles have always been designed with electronic and electrical modules, computers, fuse boxes, batteries, electric motors, parking sensors, etc. The difference between a gasoline and electric vehicle is the battery, which is protected against road hazards. The reason why our treatment can be performed quickly and efficiently is because our work skills and expertise have allowed us to do so since we have been treating electric and hybrid vehicles for over 20 years.

How does rust form?
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.

Is rust always visible?
No. It begins as a microscopic form that is not visible to the naked eye. When it appears it is too late to act. Also, don’t forget about all the hidden areas of your car where rust can develop without you knowing: door panels and hood, rear fenders, frame, uprights and rocker panels. For these reasons, it is important to treat your car once a year to prevent rust from forming.

What are the main factors that contribute to rust?
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.

How and where does rust attack a vehicle and why should it be treated with rust proofing every year?

• 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 lifetime 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.

Why should I treat my car once a year?
Our climate is so harsh that most rust proofing products lose their effectiveness over time. The salt and calcium 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.

Should I protect my new vehicle against rust?
Yes, as soon as possible. This will prevent the corrossion process from starting.

I have a used vehicle. Is it necessary to protect it against rust?
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.

Is Metropolitan’s rustproofing treatment guaranteed?
Yes, garantees free of charge are available for new and 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. One of our experts will need to inspect your vehicle before granting the guarantee.

Can the rustproofing treatment remove existing rust?
Our rustproofing product can not remove existing rust, but it may slow its progression and prevent new rust from forming.

It generally takes between 35 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.

Do I drive on sandy roads after getting my car rustproofed?
No, avoid sandy roads for at least 24 to 48 hours. Earth, sand and dust will create a crust in certain areas and absorb the product, which will reduce efficiency.

Is your rustproofing treatment compatible with my hybrid or electric vehicle?
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.

My vehicle is freshly painted or had a few paint touch-ups, should I wait before my rust proofing treatment?
