Salt is the single biggest threat to a vehicle's lifespan in this province. It works from underneath, and by the time rust shows on the body it has usually been eating the frame and brake lines for years.

Rubberized undercoating lays down a thick, durable barrier across the underbody, sealing the metal off from salt, moisture, and stone chips. It also cuts a noticeable amount of road noise from the cabin.

Price depends on the size of the vehicle, since a truck has considerably more underside to cover than a sedan.

Common questions

How often should undercoating be applied?

The rubberized coating we apply is durable, but it's worth inspecting annually and touching up where stone chips and road debris have worn it through. Ontario's road salt finds any gap you leave it.

When is the best time to undercoat?

Late summer or early fall, before the salt goes down. The underbody needs to be clean and dry for the coating to bond properly, which is much easier to achieve before winter than during it.

Is it worth undercoating an older vehicle?

It depends on what's already there. Surface rust can be treated and sealed, but coating over heavy scale just hides it — we'll put it on the hoist and give you an honest answer before you spend the money.

Does undercoating do anything besides prevent rust?

It noticeably reduces road and tire noise inside the cabin, since the coating damps vibration in the floor pans and wheel wells. That's a side benefit, not the reason to do it.
