What Is Included in the Price
Your vehicle is raised on a professional lift for thorough access to all undercarriage surfaces. We inspect the current condition and photograph any existing corrosion for your records.
The undercarriage is pressure-washed to remove existing salt, calcium, dirt, and loose debris. This ensures the oil adheres directly to metal surfaces — not on top of contamination.
Heated oil is sprayed at high pressure across all undercarriage surfaces — frame rails, crossmembers, suspension components, and control arms. Special nozzles access internal cavities and enclosed spaces.
Inner wheel wells and fender liners receive direct treatment — these areas get the heaviest salt spray exposure from your own tires.
Final inspection to verify complete coverage. We provide before/after photos and a recommended maintenance schedule for your next application.
Cost Comparison: Protection vs. Repair
Undercoating Cost vs. Rust Repair Cost (10-Year Period)
Ten years of annual professional undercoating ($3,500 total) costs less than a single major rust repair. The financial case is overwhelming.
When to Book Your Undercoating
The ideal timing follows Calgary's salt season, and if you are weighing the spend on an older vehicle it helps to understand whether undercoating a used rusty car is worth it before booking:
- September–October (ideal): Apply before the first snowfall and salt deployment. This gives you maximum protection through the entire damage season with a freshly applied barrier.
- November–December (good): Still valuable — protects through the remaining 4–5 months of heavy salt exposure. The undercarriage should be thoroughly washed before application to remove accumulated early-winter salt.
- January–March (acceptable): Late-season application and protects through the worst months and into spring when loose gravel remains on roads. Better late than not at all.
- April–May (maintenance): Spring application after the salt season is a good option for vehicles that were treated in the fall and need reinforcement for spring road construction season.
In our Calgary shop, the customers who get the most value are the ones who treat a vehicle before its first winter — clean, bare metal takes the oil beautifully and there is no existing corrosion to fight. We see the opposite case just as often: trucks that arrive after three or four salt seasons with scale already forming on the frame rails, where we spend half the appointment on prep before a drop of product goes on. That difference in starting condition is exactly why the $899 Complete Defense package pays for itself fastest on newer vehicles — you are locking in protection while there is still nothing to repair.
