SEASONAL PRODUCTS
SALT NEVER SLEEPS
Road salt and liquid brine cling to your underbody long after winter storms end. These chemicals attack metal whenever moisture is present. Without protection, corrosion continues year-round.
RUST HIDES FROM YOU
Most rust begins inside seams, overlaps, and hidden cavities. By the time rust is visible, damage is often already advanced. Preventative protection targets these hard-to-reach areas early.
PROTECT BEFORE IT STARTS
Rust prevention is most effective before corrosion takes hold. Seasonal application helps block moisture and salt before damage begins. It’s easier—and cheaper—to prevent rust than repair it.
SEASON-SPECIFIC PROTECTION
Each season creates different rust risks. NHOU seasonal products are tailored to address changing weather, road conditions, and moisture exposure throughout the year.
Defy the Elements
Modern vehicles are built with lightweight metals and complex seams that trap moisture and road salt—prime conditions for rust. NHOU undercoatings are engineered to penetrate deep into seams, spot welds, and folds, blocking out moisture and oxygen to stop corrosion at the source. Our Mil-Spec formulas are lab-tested and proven in real-world conditions to deliver long-lasting rust protection.

Frequently Asked Questions
Each season exposes your vehicle to different corrosion risks. Winter salt and brine accelerate rust, spring moisture traps contaminants, summer humidity sustains corrosion, and fall is the ideal time to prepare before harsh conditions return. Seasonal protection ensures the right areas are protected at the right time.
For best results, NHOU oil-based protection is recommended once per year. Annual reapplication helps maintain coverage in high-impact areas and ensures continued protection as road conditions and weather change.
Yes. NHOU products are designed to be safe for metal, brake lines, wiring, rubber components, and factory coatings. Application avoids heat-sensitive areas such as brakes and exhaust components while focusing on the underbody, seams, and corrosion-prone zones.
