Steps in the Metropolitan Rust Proofing treatment process:

Step 1: Vehicle Preparation

A visual inspection of the vehicle is completed;
Protective paper is placed on the seat and floor of the vehicle;
Holes are drilled in strategic locations to ensure optimal treatment. If holes have already been drilled, the existing plugs are removed;
A sticker for the current year is applied on the inside of the door certifying that the vehicle was treated at Metropolitan Rust Proofing.

Step 2: De-icing and/or Drying

In case of rain or snow, dryers are used to dry and/or de-ice the vehicle before the product is applied;
Our industrial dryers are rated up to 500,000 BTU and are specifically designed for our requirements;
The unique design of the dryers allows for the drying of hard-to-reach areas in order to improve the infiltration of the antirust product.

Step 3: Vehicle Undercarriage

The Primary Treatment Areas are as follows:

The entire undercarriage;
Front and rear wheel wells;
Front and rear bumpers.

Step 4: Vehicle Body Interior

The Primary Treatment Points are as follows:

The hood and motor compartment;
Hinges;
Front and rear fenders;
Undercarriage;
Rear trunk hood;
Interior of door bottoms;
Gas tank door (if applicable).

Step 5: Window Cleaning

Before the vehicle is returned, it is rinsed off using a high-pressure water system to remove any excess oil;
Careful attention is paid to ensure that vehicle windows are clean;
They are carefully cleaned in order to remove any traces of oil that may hinder visibility while driving;
Following this, the vehicle is left to dry for a short time before being returned to the owner.

Step 6: Vehicle Return

Following a brief inspection of the vehicle, all protective papers are removed and the areas touched by technicians are cleaned in order to remove any traces of oil that may affect driving on the way home;
Finally, the customer is provided with a few recommendations and warnings prior to departure.

In Case of Rain...

You made an appointment to have your annual rust protection treatment applied on your vehicle more than a week ago but on the day of your scheduled treatment - it rains. What to do? You know the metal on your vehicle will be wet when you arrive at the treatment centre and are worried that the effectiveness of the treatment may be reduced.

Don’t worry!

First, when the product itself comes into contact with water, it forms a gel in the cavities and cracks in the metal and fills them with antirust gel, thereby eliminating any traces of humidity.

Second, each treatment centre is equipped with an industrial dryer (up to 500,000 BTU!) that ensures the vehicle is completely dry before treatment.

The same process is used during the winter. The dryers are used to dry and de-ice the metal areas on your vehicle as well as warm them up, which improves the effectiveness of the treatment.

As a result, regardless of what Mother Nature has in store, you may rest assured that on the day of your treatment, there is nothing to worry about. Metropolitan Rust Proofing has thought of everything to ensure that your treatment is as effective as possible.

Drilling

When they arrive for their first antirust treatment, some car owners are shocked to learn that holes are actually drilled into their vehicle. This operation, called drilling, is probably one of the most misunderstood steps in the treatment. In fact, the drilling process simply allows us to reach strategic areas within the vehicle, such as inside the undercarriage and inside the doors.

Undercarriages

The undercarriage is drilled in two locations on two-door models and in three places on four-door models (2 in front and one in the rear) in order to allow the treatment to reach closed-in areas where humidity tends to accumulate. What’s more, undercarriages are particularly susceptible due to their function and construction: accumulation of calcium deposits during the winter, wear caused by doors being opened and closed, several welds and crimping points, etc. The undercarriage is usually one of the first areas where rust will begin to appear on non-treated vehicles.

Note: Each drill hole is filled with a blend of grease and oil and capped with a black plug. The holes are approximately ½ inch in diameter. Hole locations may vary depending on the vehicle model.

Doors

Doors are drilled in a single location approximately 15 cm from the bottom. The bottoms of doors are typically very prone to rust for three reasons: it is easy for humidity to access the door interior, wear caused by the opening and closing of the door, and high number of crimps in the metal. By drilling the door, technicians can easily access the door interior to ensure uniform application of the product.
