About NHOU®

What We Couldn’t Buy, We Built

A New Hampshire family business that started in the shop beside our home.

NHOU® began with one truck we weren’t ready to give up on. What we learned saving it became the products, training and support we offer today.

Where we started

A Truck We Weren’t Ready to Lose

We had a truck we depended on, and rust was taking it away long before its time. Replacing it wasn’t an option. When we were told there was nothing we could do, that didn’t sit right.

So we went to work in the shop beside our home. We listened to neighbors who had oiled their trucks for years, read everything we could about oil-based rustproofing, and spent a lot of nights blending, testing and trying again. We weren’t trying to start a business. We were trying to save our truck.

It worked, and word got around: first friends, then neighbors, then people we’d never met with the same problem. Back then, rustproofing wasn’t something most people around us thought about. We helped a lot of them see that they didn’t have to wait for rust to win. They could protect their vehicles before it started.

What we learned along the way

Every Vehicle Taught Us Something

The business grew one vehicle at a time. We worked on trucks, cars and equipment, listened to what customers told us, and kept improving what we did. That experience shaped our products, our training and the support we give other shops.

We’re still a family business solving practical problems. We’re in the shop, in the office, and on the phone when you call.

Our products

When the products available didn’t hold up, we worked with corrosion engineers and chemists to make our own, starting with NHOU® Original Oil in Clear and Black, and later V3. Every formula is tested in our New Hampshire lab and on the vehicles we treat in our own shop.

Our training

We teach what we’ve learned: workshops for vehicle owners, and hands-on training for shops and public fleet crews.

Our support for shops

Shops that apply NHOU® products get the same practical advice we use every day, from equipment and application to answering customers’ questions.

Why we built RustFax and My Steward Registry

So You Can See What’s Underneath

Most of what we do happens underneath the vehicle, where customers can’t easily see it. We think you should be able to see what was found and what was done to protect it.

That’s why we built RustFax. Technicians document each inspection and service with photos, video and notes tied to the vehicle, and you receive a report of the work. Through My Steward Registry, you can claim your vehicle and keep adding to its care history, so when it’s time to sell, you can show how well it was looked after.

RustFax reports are available at our Chichester shop and participating locations.

Where this is taking us

From One Truck to Public Fleets

The problem we set out to solve beside our house is the same one towns face every winter, on a bigger scale. Plow trucks, loaders and other public equipment paid for with taxpayer money are wearing out sooner than they should.

Initiative underway

We’re working with New Hampshire lawmakers on a proposal to make documented corrosion-prevention planning part of caring for public fleets. The goal is to help communities take better care of the equipment taxpayers have already paid for.

This is a proposal in progress, not a law that has passed. In the meantime, we’re already helping towns and public fleets build documented protection programs.
