Rustproofing

Yearly protection of the underbody and cavities against salt and corrosion.

Service description

The treatment involves spraying a specialized protective product into the body cavities and under the vehicle. The product acts as a barrier that repels moisture and slows down rust.

Why does it matter?

In Québec, the salt and calcium used on the roads attack your car’s metal directly. This corrosion can weaken the structure, damage mechanical components and lower your car’s resale value. Regular rustproofing works like a waterproof shield that protects your investment.

When to plan this service?

Item	Recommendation
How often	Ideally once a year, without exception, so the protective barrier stays effective against the weather.
Best time	Often planned in late summer or fall (September to November), just before roads start being salted.
