Rust is your vehicle’s most persistent enemy. Salt, moisture, and oxygen work together to corrode steel from the inside out—especially in seams, spot welds, frames, and hard‑to‑reach cavities. KROWN is a petroleum-based rust inhibitor engineered to stop that process at the source by displacing moisture and forming a persistent, protective film on metal surfaces. It’s non-toxic, non-reactive, non-flammable, non-corrosive, contains no solvents, and can be applied in any weather—so you can protect your vehicle year-round.

How KROWN works

  • Penetrates and creeps: KROWN’s low-viscosity formula uses capillary action to “creep” deep into seams, folds, spot welds, and hidden cavities that traditional coatings can’t reach.
  • Displaces moisture: It pushes water and brine away from metal, breaking the electrochemical conditions rust needs to form and spread.
  • Forms a mobile barrier: Unlike hard coatings that dry, crack, and trap moisture, KROWN remains active. It self-heals minor disturbances and continues protecting even as panels flex and temperatures change.
  • Protects more than bare metal: It helps shield brake and fuel lines, electrical connectors, battery terminals, and wiring harnesses from corrosion-related failures.

What it does for your vehicle

  • Slows existing corrosion and prevents new rust by removing moisture and oxygen from the equation.
  • Preserves structural integrity of frames, crossmembers, and rocker panels—areas that are costly to repair and critical for safety.
  • Reduces corrosion on fasteners and fittings, making future service easier and lowering lifetime maintenance costs.
  • Helps maintain clean electrical connections, reducing intermittent sensor faults and corrosion-related diagnostic headaches.

Why spray-on rust protection is the best approach

Compared with alternatives, an annual, penetrating spray like KROWN provides the most complete, durable coverage in real-world conditions:

  • Versus rubberized or paint-on undercoating: Hard coatings can look good on day one but often crack from road impacts and seasonal expansion. Once breached, they can trap salt and moisture against the metal, accelerating rust. KROWN stays flexible, creeps into new micro-gaps, and won’t entomb corrosion.
  • Versus wax-asphalt blends: These build thickness but lack the same creep and moisture displacement. They’re easier to miss in seams and around spot welds—precisely where corrosion starts.
  • Versus electronic “rust modules”: Automotive bodies aren’t uniformly submerged anodes. Independent evidence for electronic inhibitors on vehicles is weak; they don’t displace moisture, can’t penetrate seams, and don’t protect wiring or lines. KROWN addresses the root cause—water and salt—mechanically and immediately.
  • Serviceability: KROWN’s film can be renewed annually without stripping; hard coatings often require grinding or patching once compromised.

Benefits for different owners

  • Car owners: Keep daily drivers quieter and cleaner underneath, avoid premature rocker, wheel-arch, and brake/fuel line failures, and preserve resale value. A yearly KROWN application typically costs far less than even one corrosion repair.
  • Truck owners: Frames, bed seams, cab mounts, and leaf spring perches are high-risk zones—especially with towing, off-road use, and winter salt. KROWN creeps into boxed frames and crossmembers, protecting the places trucks rust first.
  • Fleets: Fewer corrosion-related breakdowns, less downtime, and more predictable maintenance budgets. Chassis, harnesses, and connectors last longer, and residual values improve across the fleet. An annual program standardizes protection and recordkeeping.

How often should you apply it?

Once a year. Corrosion activity increases with temperature, so protection matters in spring and summer as much as winter. Annual reapplication ensures the barrier remains active across seasons and vehicle use. Krown offers warranty programs for qualifying new and used vehicles—ask your local dealer for details.
