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.
Growing Your Business
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. Quality vehicle protection products, solving problems and excellent customer relationships are the core of our brand. We strive to work with people and businesses that understand that a quality product applied by professionally trained applicators is the key to our mutual success.


Loyal Customers—and More of Them
Because we use all the products we engineer, we have a unique opportunity to not only accurately gauge performance, but design our products to be user-friendly. 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.
Oil-based Rustproofing – Where is the proof?
At the NHOU Flagship Location, we are proud to announce that our Oil-based Rustproofing service is on track to undercoat over 3,500 vehicles this year alone. With the recent opening of our larger facility in Concord, NH, as of January 2015, we are well-positioned for continued growth.
If you’re still unconvinced about the critical need for oil-based rustproofing in the United States, look no further than our Canadian neighbors. They boast thousands of businesses offering undercoating services, with some treating as many as 250,000 vehicles annually, from British Columbia all the way to Montreal. Oil undercoating has been a key part of their vehicle maintenance culture for over 30 years, and it continues to thrive.
The factors here in the United States are equally compelling. As new vehicle prices soar and the emphasis on fuel efficiency (MPG) leads to thinner metals, the urgent need for effective corrosion protection is clear. With the growing corrosiveness of road salt and liquid brines, investing in rustproofing has never made more sense. We’re ready to meet that demand and protect your vehicle investment.

Comparing NH Oil-based Rustproofing® to other Oil-based Rustproofing Products
Our undercoating business launched in 2010 with a diverse range of multi-use products. Over the years, we have applied thousands of undercoatings, gaining invaluable insights into their performance. By our third year, we recognized specific challenges in longevity and odor that needed addressing. Additionally, the overspray was excessive, requiring us to keep our garage doors open while spraying — a limitation that halted our work in colder weather.
Determined to overcome these obstacles, we partnered with corrosion engineers and an industry chemist with over 40 years of experience in automotive coatings to innovate and improve our offerings.
As a result, we proudly developed NH Oil Undercoating®, Boss Wax®, and Rusoration® Rust Converter, which embody the best features of our initial products. Our formulations excel in moisture displacement, creeping and migrating capabilities, corrosion inhibition, and lubrication, making them effective and affordable. We have dramatically minimized overspray and infused our products with a pleasant aroma.
With several years of experience and thousands of successful applications, NH Oil Undercoating® has garnered exceptional reviews from customers and dealers alike.
Join us in the battle against rust, turning it into a straightforward maintenance task that can save consumers thousands in costly repairs. This partnership will not only enhance your profitability but will also attract hundreds of new customers each year. We offer competitive pricing, but the unmatched customer support and expertise we provide are truly priceless!
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.
