Your Ultimate Rustproofing Solution, Now Available at Carlat.com in Europe


Why Rustproofing Matters

Rust is more than just a cosmetic nuisance—it’s a serious safety concern that can compromise vehicle components such as brake lines and structural elements. In fact, an estimated 70% of U.S. drivers are affected by rust, with around 22 million experiencing rust-related damage in the last five years alone. When de-icing chemicals like salt and brine come into contact with metal parts, the corrosion process accelerates. The result? Costly repairs and a shorter vehicle lifespan.

But rust can be prevented. By choosing a high-quality undercoating solution, you can extend your vehicle’s life and protect its value—whether you drive a car, SUV, pickup truck, or commercial vehicle. That’s where NH Oil Undercoating® (NHOU) comes in.


Introducing NH Oil Undercoating®

NHOU is an advanced, oil-based rustproofing system engineered to protect your vehicle from the inside out. Each NHOU formula uses highly refined food-grade mineral oil combined with eco-friendly corrosion inhibitors, effectively displacing moisture and sealing out oxygen. By removing moisture and oxygen—the two main components that cause rust—NHOU undercoatings help ensure your car stays safe on the road.

Key Benefits of NHOU Products

  • Self-Healing: Formulas continue to coat and protect even after minor scrapes.
  • Eco-Friendly: Free of solvents, detergents, and harmful chemicals; all corrosion inhibitors are derived from plant and animal fats. Even the tint in NHOU Black is biodegradable.
  • Deep-Creeping Action: Over time, the product migrates several inches into nooks and crannies—particularly important in rocker panels and door seams where rust often begins.
  • Surface-Friendly: Light surface rust can actually enhance adhesion, giving the formula more texture to grip.

NHOU’s Product Range

  1. NH Oil Undercoating® (NH Clear)

    • Clear Formula: Ideal for new or slightly used vehicles when you want a nearly invisible coat.
    • Powerful Blend: Combines refined mineral oil with green corrosion inhibitors to push out moisture and guard against salt, dirt, and debris.
    • Key Advantage: Perfect for drivers who want top-notch rust protection without altering the appearance of their undercarriage.

    • Multi-Layer Method: Often applied first on exposed areas, then followed by NH Oil Undercoating® for maximum durability and extended rust prevention.

Advanced Rust Protection, Backed by Experience

NHOU’s formulations aren’t just random blends; they are purpose-engineered and laboratory-tested under the guidance of founder Joe Dupont, who works closely with corrosion engineers and chemists with decades of experience. Each product is tested both in labs and in real-world conditions on thousands of vehicles treated every year at the NHOU facility in New Hampshire.

  • Continuous Improvement: NHOU is constantly refining and upgrading its formulas as science and technology progress.
  • Family-Owned Roots: What began as a part-time operation in a small garage has evolved into a globally recognized brand. Despite their growth, NHOU remains committed to personalized service and hands-on product development.

The Story Behind NHOU

Founder Joe Dupont was frustrated by persistent rust problems on his truck in New England. Determined not to lose his primary work vehicle, he researched solutions and discovered the oil-undercoating techniques popular in Europe. Through collaboration with engineers and chemists, Joe developed a specialized, environmentally friendly oil-based solution that far exceeded the performance of generic products. Today, NH Oil Undercoating® offers several advanced, proprietary formulas trusted by thousands of drivers.
