At Northern Undercoatings, rust protection isn’t an add-on service – it’s what we do.
Based in Greenville, New Hampshire, we specialize in undercoating and rust protection for the vehicles that take on New England roads every day. From daily drivers and work trucks to commercial and municipal fleets, our focus is simple: protect what you drive and help keep it on the road longer.
As a proud NHOU dealer, we use professional-grade rust protection products and application methods designed to reach the areas that matter – including frames, rocker panels, doors, tailgates and other hard-to-reach cavities where corrosion can start.
Every vehicle is different, and we treat it that way. Before we spray, we take the time to inspect what happening underneath and determine what prep is needed. If we find loose or scaling rust, we address it and keep you informed. That way, when it’s time to undercoat, your vehicle is properly prepared for the protection we’re putting on it.
Undercoating is what we do. Protecting what you drive is why we do it.
NHOU Original Oil Undercoating
Proven Corrosion Protection That Gets Into the Places You Can’t See
A petroleum-based rust prevention treatment designed to protect vehicles from the damaging effects of moisture, road salt, and environmental exposure.
Unlike traditional hard coatings that can crack, chip, or trap moisture underneath, NHOU Original remains fluid and continues to migrate into seams, crevices, and hard-to-reach areas where corrosion commonly begins.
One of its greatest advantages is its ability to creep into tight spaces, making it particularly effective for protecting internal frame cavities, rocker panels, door bottoms, and other enclosed areas.
The oil creates a protective barrier that helps prevent moisture and oxygen from reaching exposed metal surfaces, slowing the corrosion process and helping preserve the vehicle’s structural integrity.
Key Benefits:
NHOU V3 Oil Undercoating
Enhanced Durability with the Protective Benefits of Oil
An advanced oil-based corrosion protection formula developed for customers seeking increased durability while retaining the important protective characteristics of traditional oil undercoating.
V3 incorporates a wax component into the oil, creating a thicker, more substantial protective coating that is designed to remain in place longer than our Original formula.
This makes V3 particularly effective on exposed undercarriage components, including frames, suspension components, and other areas subjected to harsh winter driving conditions.
Although thicker than Original NHOU Oil, V3 still provides migration and penetration into seams and crevices, helping protect vulnerable metal surfaces.
Key Benefits:
NHOU Boss Wax Hybrid
Premium Long-Term Protection for Newer Vehicles
NHOU Boss Wax Hybrid is our premium wax-based corrosion protection system, designed primarily for new and exceptionally clean vehicles.
Unlike conventional oil undercoatings, Boss Wax Hybrid forms a thicker, more durable protective coating that adheres to metal surfaces and creates a long-lasting barrier against moisture, road salt, and environmental contaminants.
The formula combines the durability of a wax coating with oil-based protective characteristics, helping the coating maintain flexibility rather than becoming excessively brittle.
Boss Wax Hybrid is particularly well suited for customers who want to protect a new vehicle before corrosion has an opportunity to develop.
Because this product is designed to form a durable protective layer, proper surface preparation and application are especially important.
Boss Wax Hybrid is not generally recommended for heavily rusted vehicles, where a more penetrating oil-based treatment is typically the better choice.
Key Benefits:
Real vehicles. Real rust protection.
