Rustproofing in Montreal

Rustproofing at Garage Path57 costs $100 for a car, $120 for an SUV and $140 for a truck.

Why it matters in Montreal

Quebec spreads road salt from November to April. Mixed with water and slush, that salt works into the underbody, rocker panels, brake lines and weld points. Corrosion starts where you cannot see it and shows up years later — often once it reaches a safety component.

What the treatment does

Paraffin is applied to the underbody and inside cavities. It forms a flexible barrier that does not crack in the cold and creeps into seams where salt collects. Unlike a rigid coating, it does not trap moisture under a cracked crust.

When to do it

In the fall, before the first salting. Once a year. On a new vehicle, starting in year one gives the best result — you protect before corrosion begins, not after.

Rustproofing or not: the honest answer

On a vehicle you plan to keep more than three years in Montreal, yes — $100 a year against a structural corrosion repair that runs into the thousands. On an end-of-life vehicle you are selling this spring, the case is weak. We will tell you so.
