“Great experience and service. I’ll definitely be back next year.”

Monica • Rust Proofing & Protection at Krown Rust Control, Cornwall
★ ★ ★ ★ ★

“Cornwall Krown has an online booking system that is easy and fast. Jessie explained that as a first time undercoat to my new-to-me suv, he would be making holes so that the chemicals would get into all crevices and protect the undercariage well. It took less than the hour scheduled, and I was advised on parking on the street for a few days post-process, so as to not have drips in a driveway. Excellent advice! Thank you Jessie, for the all around awesome experience!”

What Causes Vehicle Rust in Canada

Road salt (calcium chloride and sodium chloride) attacking bare metal
Moisture trapped in crevices, door panels, and wheel wells
Stone chips exposing bare metal underneath the paint
Drainage holes clogged with debris allowing standing water
Older vehicles with thinner factory undercoating wearing away
Winter driving requiring constant exposure to salt brine and sand

Signs Your Vehicle Needs Rust Protection

Bubbling paint on wheel arches, rocker panels, or door bottoms
Visible surface rust on the frame, subframe, or suspension components
Rust-through holes forming on body panels or the floor
Brown stains around panel seams and weld joints
Crumbling undercoating that no longer provides protection
Body panels that feel soft or thin when pressed

Rust Proofing & Protection Tips

Apply rust proofing annually before winter for maximum protection
Wash your vehicle's underbody frequently during salt season

Oil-based sprays are generally considered most effective for Canadian conditions
New vehicles should be rust-proofed immediately—factory protection is minimal
Keep drainage holes in your doors and rocker panels clear of debris

Frequently Asked Questions

How much does rust proofing cost in Cornwall? +
Annual oil spray rust proofing costs $120-$180 for cars and $150-$220 for trucks and SUVs. One-time rubberized undercoating costs $300-$600. Electronic modules start at $400-$600 installed.
Is rust proofing worth it on a new car? +
Absolutely. Factory corrosion protection is minimal, especially on the frame and subframe. An annual oil spray starting from year one significantly extends the vehicle's structural life in Canadian climates.
Which type of rust proofing is best? +
Oil-based annual sprays (like Krown or Rust Check) are widely considered the most effective for Canadian conditions because they penetrate into seams, crevices, and hard-to-reach areas that rubberized coatings miss.
Can you rust-proof a car that already has rust? +
Yes, but existing rust should be treated with a rust converter first. Rust proofing will then slow further progression, but it cannot reverse damage that has already occurred.
