Stop the rust.Undercoating & rust proofing in Calgary — from $599.

For a car you plan to keep, yes — it's one of the best-value things you can do here. Our roads get treated with magnesium-chloride brine, road salt, and a gravel 'pickle mix' that stick to your undercarriage and keep eating metal even after they dry, working on frame rails and brake lines year-round. Protection runs roughly $599–$1,299; the average rust repair starts at $3,500+. It's cheaper to seal it now than to cut out perforation later.

Neither is 'better' on its own — they do different jobs. Oil-based creeps into seams, pinch welds, and hidden cavities to fight rust from the inside out, but it's an annual commitment: you reapply every year for it to keep working. Rubberized forms a tough hard shell against gravel and road spray that lasts 2–3 years. If you're keeping the vehicle through Calgary winters, our Full Defense package runs both — a rubberized shell plus oil-based cavity wax injection — which is honestly what most of our trucks and daily drivers need.

Undercoating starts at $599 for a coupe or sedan, $699 for an SUV or truck, and $799 for exotics. Standalone rust-proofing runs $399–$499, and our complete undercoating-plus-rustproofing package is $999–$1,299 depending on vehicle size. A quick inspection confirms the exact price for your build.

No. In Canada a dealer can't void your mechanical warranty just because you had third-party rust protection done. We mask off the exhaust, catalytic converter, and sensors before we spray, so the product stays clear of factory components and your coverage stays intact — that's also why an independent specialist is usually a smarter buy than a dealer rust package.

Late spring and early summer is the ideal window — it's the perfect time to inspect last winter's salt damage and book before the fall rush. Application bonds best to completely dry metal, so spring, summer, and early fall are all excellent. We can apply year-round, but a winter booking needs a thorough wash-and-dry cycle in our shop first.

Oil-based undercoating is designed to be reapplied annually, since it penetrates seams and slowly works deeper over time. Rubberized hard-shell coating lasts 2–3 years but should be inspected each year, and the internal cavity wax inside doors and rocker panels should be checked annually. We recommend a yearly inspection-and-refresh to keep your protection working.

No. Before application, we carefully mask off the exhaust, catalytic converter, and all vehicle sensors so coating never touches heat-sensitive or electronic components. The product is applied only to frame rails, body panels, suspension areas, and cavities, leaving your vehicle's systems untouched.

Undercoating shields your undercarriage from the corrosive cocktail Calgary spreads on roads like Deerfoot and Stoney Trail — magnesium chloride brine, road salt, and gravel pickle mix. These agents stay corrosive even when dry, driving the three-stage corrosion process from surface rust to deep penetration in seams to permanent perforation. A sealed barrier plus cavity wax stops that process before it reaches the frame.
