Better protection, longer lifespan

Why Rustproof Your Vehicle?

Ontario roads are salted from November through March. Rust starts where you can't see it, inside the cavities and under the vehicle, long before it shows on the paint.

01

A longer life for your vehicle

Rustproofing keeps the metal strong, solid and road ready for the long haul.

02

Salt is rust's favourite snack

A proper application keeps road salt and moisture away from bare metal all winter.

03

Fewer surprise repair bills

Rust doesn't stop at looks. It eats into brake lines, fuel lines and the frame underneath.

04

Better resale value

Buyers check underneath. A clean underbody keeps more money in your pocket when you sell.

05

Cheaper than fixing rust later

Like dental work, repair is painful and pricey. Prevention is the easy part.

Two zones, full coverage

Where We Protect Your Vehicle

Underbody protection and inner cavity protection do different jobs. For full year round protection, most owners choose both.

The image appears to illustrate key structural or protective areas of the vehicle.

Tailored packages

Rustproofing Packages That Make Sense

We choose the product based on what's best for your vehicle, not what looks the thickest or sounds the fanciest.

New vehicles

New Vehicle Package

Protect it before rust ever has a chance.

  • The only stage where prevention is 100% proactive
  • Seals clean metal before corrosion can begin
  • Protects factory seams, welds and cavities from day one
  • Preserves structure, value and resale

Best time: as early as possible, while the vehicle is still rust free.

Used vehicles

Used Vehicle Package

Protect what's solid. Slow what's started.


Underbody: dripless wax based coating that protects existing metal without trapping moisture.

  • Protects solid metal before rust spreads
  • Slows existing surface rust and stops new rust forming
  • Reaches the seams and cavities where rust starts first
  • Built for real Ontario driving and winters

Electric vehicles

EV Package

Built specifically for electric vehicles.


Underbody: amber wax only. Never rubberized, so nothing seals over your battery or electrical components.
Inner cavities: amber wax through factory openings only.

  • EV safe formula with no sealing agents
  • Applied through existing drain holes, no drilling
  • Low pressure, nowhere near high voltage cabling, battery pack or charge port
  • Dripless, so nothing migrates onto sensitive components

Best time: before your first salt season. Your EV has a steel body and subframe that faces the same winters as everyone else.

Rustproofing process

Our 6 Step Process

Step 01

Check-in and inspection

We inspect your vehicle, recommend the right package and take the time to explain why and answer your questions.

Step 02

Masking and protection

Fresh seat, wheel, shifter and floor covers go in. Nothing contaminated enters your vehicle.

Step 03

Cavity spray

Through factory openings and drain holes, we treat the doors, rockers, pillars and hidden cavities. No drilling, ever.

Step 04

Underbody application

A clean, dripless application across all major underbody contact points.

Step 05

Exterior hand wash

A free 2 bucket hand wash removes any overspray and avoids water cross contamination.

Step 06

Final review and photos

We verify even coverage, complete a photo walkthrough (coming soon) and disinfect the vehicle before handoff.

Why it matters

We Know the Cost of Waiting

We've watched clean looking trucks end up in the shop for major frame rebuilds because the underbody was left unprotected.

Once rust turns structural, it isn't a simple fix. It's thousands in specialized fabrication. Protect your original frame now and keep your vehicle on the road.

Before: underbody damage you can avoid by rustproofing.

During: underbody repair, a service we also provide.

After: underbody protection following a costly repair.

Long lasting prevention

After Your Appointment

Let it settle

  • First 48 hours: avoid gravel roads and heavy rain so the coating can settle
  • First couple of weeks: skip pressure washing wheel wells and the engine bay so the product can fully set
  • Once it sets, it works on its own with no extra care needed

Keep it strong

Our treatment is built to last, and a yearly touch up keeps it in peak condition. We send automated reminders so you never miss your annual application.

FAQs

Rustproofing Questions, Answered

How long does rustproofing take?

Most vehicles take 45 to 60 minutes, depending on the package.

Is your product dripless?

Yes. Our formula is fully dripless, so there's no mess on your driveway.

Do you drill into my vehicle?

No. We use factory openings and drain holes only.

Is overspray a possibility?

No. We use a clean, controlled application process that prevents overspray, followed by a complimentary exterior hand wash.

Can you rustproof an electric vehicle?

Yes. Our EV Package uses amber wax only, applied at low pressure through existing drain holes. We never apply rubberized coating to an EV, and we stay clear of the high voltage cabling, battery pack and charge port. If you only want the cavities done, inner cavity only protection is also available.

How often should I rustproof?

Once a year for optimal protection. We send automated reminders so you never miss it.

Do you offer a warranty?

Yes. You receive one year of coverage with free reapplication if needed, plus automated reminders.

Does wax based protection stop rust?

It can't reverse existing rust, but it slows the spread by sealing out moisture and oxygen. Think of it like sunscreen: it doesn't undo damage, it helps stop it getting worse.

Why is wax based protection best for used vehicles?

A thick rubberized coating over existing rust can trap moisture and speed up corrosion. That's why we never rubberize the underbody of a used vehicle. Wax flows into seams, coats existing metal and slows corrosion without sealing it in.

Why isn't wax ideal for the underbody of a new vehicle?

It's too thin for exposed areas. Wax is excellent inside the cavities, but it lacks the durability to protect the undercarriage from stone chips and constant road spray. On new vehicles we use wax inside the panels and a rubberized coating underneath.

Why is rubberized undercoating better on new vehicles?

It seals the new in. Rubberized undercoating works best on clean, rust free metal, creating a thick, lasting barrier against salt, water and stone chips. Like putting a case on a brand new phone before it gets scratched.
