Becoming an NHOU® Authorized Dealer


As an automotive business owner, you’re already well-positioned to offer NHOU’s products and services to your customers—helping them get the most out of their vehicles. At our flagship shop in Chichester, New Hampshire, we provide oil undercoating to thousands of vehicles a year, with over 90% of our customers returning year after year for annual service. Some of our dealers have gone on to build dedicated service bays exclusively for applying NHOU® products—and some have had the income from NHOU® services exceed all their other earnings.



Premium Rustproofing Products & Services

NHOU® has been specializing in oil-based rustproofing and undercarriage rust prevention since 2010. We engineer, test and manufacture highly effective and affordable NH Oil Undercoating®, BOSS WAX®, Mouse-Out Rodent Deterrent, Rustoration® Rust Converter, NHOU® Salt Brine Eliminator, and NHOU® Ceramic Coating products. NH Oil Undercoating® comes in clear and black—with the black oil comprising 80% of our business. Our newest product, NHOU®-ENVIRO is 100% biobased and biodegradable, making it ideal for municipal fleets and agricultural vehicles.

We genuinely care about helping you grow your business—big or small—through the voices of your own customers. We’ll help you showcase your hard work and the passion you have for your clients by offering an easy-to-navigate link directly to Google reviews, Facebook reviews, Yelp reviews and the ratings and review app right on our store locator page.


We’re In It Together

Our goal is to establish long-term, profitable, mutually beneficial relationships with every NHOU® Authorized Dealer—and our track record for success speaks for itself, with dealers around the world.

NHOU® also has an in-house lab for the highest level of quality control. If you live in or drive in the rust belt, or an area where moisture is present and roads are treated with salt and brine, there’s a great need for oil-based rustproofing in your area. Undercoating will dovetail with your current service and attract more customers to your business.

Better to become an NHOU® Dealer than to compete with one

Oil-based Rustproofing – Where is the proof?


The Rust Stop Pros Oil-based Rustproofing will be on track to undercoat Rustproof over 3500 vehicles this year alone, and we have just opened a 2nd and larger facility in Concord, NH as of January 2015. But if our growth does not convince you that Oil-based rustproofing is badly needed here in the States take a look at our Canadian neighbors who have literally thousands of businesses offering to undercoat along with their other services from British Columbia all the way to Montreal (some undercoating as many as 250,000 vehicles per year). Oil undercoating has continued to expand and thrive in Canada and around the world for over 30 years. The dynamics are in place here in the United States. The price of a new vehicle has skyrocketed, and with the emphasis being put on MPG, the metals are thinner than ever before, combining that with the fact that road salt and liquid brines are more corrosive than ever, maintaining corrosion makes perfect sense.

Comparing NH Oil-based Rustproofing® to other Oil-based Rustproofing Products


Our undercoating business began back in 2010 with various products, two years, and thousands of undercoatings later, we had ample opportunity to observe how these products had performed. By our third year in business, there were issues with some of our customers on the longevity of this product as well as with the odor, and I must tell you the overspray was so bad that we would need our garage doors open when spraying which did not allow us to spray in cold weather. Frustrated we began to research solutions to these problems working closely with corrosion engineers In a chemist with over 40 years of experience in chemical coatings for the automobile industry About us


Together our team has developed NH Oil Undercoating®, Boss Wax®, and Rusoration® Rust Converter, which combines the best properties of the products we’ve used. Combines moisture displacing abilities, the ability to creep and migrate, corrosion inhibitors with lubricating benefits are extremely effective, long-lasting, and affordable. Minimal atomization (overspray) and a pleasant smell are built into our Formula! Several years and thousands of undercoatings later our NH Oil Undercoating® has had rave reviews from our customers and dealers alike.


I hope you will consider joining us in this fight against rust by making it just another maintenance item and saving consumers thousands in costly repair bills while making you money and attracting hundreds of new customers each year. We are competitively priced but what we offer you in customer support and experience money can’t buy!

NHOU Training facility

We simulate years of seaside exposure in a month or less with ASTM B117


In 2016 NH Oil Undercoating began the installation of a fully equipped testing lab to evaluate the corrosive properties of: Phosphated surfaces with an ASTM B-117 compliant salt fog chamber.  ASTM B 117 Salt Fog and Salt Spray testing is an accelerated method for evaluating coating and materials performance under highly corrosive marine conditions. B117 is commonly used for metals, plastics, woods, and coated materials of all kinds.


We say ‘years’ because the exact amount depends on the conditions of exposure and there is no agreed-upon correlation factor; the goal of the test is to provide a stable environment where different coatings and materials can be compared against each other.  Along with the benefit of observing and evaluating the tens of thousands of vehicles coming through the shops each year, this will help allow us to develop new products and combat the increasingly corrosive nature of new chemicals applied to the roads each year.
