Rustproofing & Undercoating in Toronto

Protect it before winter.

Rust-inhibiting undercoating and cavity wax to protect the frame and panels through Toronto winters.

Rust only ever gets worse with time — a yearly undercoating and cavity wax application slows down what Toronto's road salt does to your car's frame and panels.

  • A Few Hours

    Most applications done same-day.

  • Best Fall or Spring

    Before or after peak road-salt season.

Questions

Rustproofing & Undercoating FAQ

Does rustproofing repair existing rust?

No. Protective treatments and metal repair are different services — existing corrosion should be assessed first, especially where metal has weakened.

How long does the protection last?

It depends on how the car is driven and stored, and how many winters it's already been through. We'll give you a realistic estimate when we apply it.

When's the best time to book?

Fall, before the road salt starts, or spring, to treat what the winter left behind.
