We recommend

BOSS Wax® & Oil

Made for new vehicles. It seals clean metal before rust starts, with a clean matte black finish instead of an oily one, and it's backed by a lifetime warranty when you keep up with touch-ups.

From $1,500 cars, SUVs and trucks · $150 touch-up every 2 years

Also consider: BOSS Wax® Mil-Spec Hybrid →

Every visit includes a RustFax® report. Add the Salt-Brine Eliminator® wash to any service to strip winter salt first. Not sure? Book a visit and we'll put your vehicle on the lift and show you what we see.

Included with every visit

Your RustFax report

Before we treat anything, our technicians document what's under your vehicle. You leave with a dated report you can show anyone.

  • Inspection photos of the frame, wheel wells and underbody, as we found them
  • Technician notes and recommendations in plain language
  • Work performed during the visit, with the service date
  • Video walk-around of the underside, where included

Saved to My Steward Registry

Your report attaches to your vehicle's record. Claim your vehicle, add your own receipts and photos, and show the shop-verified rust history when it's time to sell or trade in.

Real results

Already rusty? It's not too late.

Rustoration® is our most aggressive service for vehicles with moderate to heavy rust. We remove loose and flaking rust, convert what's left into a stable base, then seal it with NHOU oil inside and out.

Every Rustoration starts and ends with RustFax photos, so you see exactly what changed.

We’ve had nothing but great experiences with NH Oil Undercoat! We previously brought our Jeep Gladiator here and were so happy with the service that we knew exactly where we wanted to bring our brand-new Ford Bronco! The team is professional, knowledgeable, friendly, and takes pride in the work they do. It’s great knowing our vehicles are getting the protection they need, especially with the harsh New England winters and road salt. We truly appreciate the quality of service and the peace of mind that comes with protecting our vehicles for years to come. We wouldn’t hesitate to recommend NH Oil Undercoat to anyone looking to protect their investment. Definitely a five-star experience, and we’ll continue coming back!

I remember NH Oil Undercoating back when they were first getting started. Joe was out there with a truck and trailer, literally getting underneath vehicles and doing the work himself. To walk in today and see what this place has turned into is pretty incredible. They've come a long way from those early days. Now they've got a huge operation, their own undercoating products, and shops using their products all over the country. Pretty impressive when you think about where it all started. Anybody who's lived in New Hampshire knows what the salt does to vehicles around here. It's great seeing a local, family-run business take something so simple and turn it into what it is today. You don't see that kind of growth without a lot of hard work and dedication. Really happy to see how far Joe and his family have come. They've certainly earned their success. Keep up the great work!

Highly Recommend NH Oil Undercoating! NH Oil Undercoating is an excellent place to go for convenient, professional service and outstanding care for your vehicle. The hospitality is exceptional, and the customer waiting area is clean, comfortable, and welcoming. It features cozy couches, a complimentary high-quality massage chair to enjoy while you wait, and free coffee, hot cocoa, and snacks. The entire facility is impressively clean and free of unpleasant odors, even with the undercoating products being applied in the outdoor service bays. If you’re looking for excellent customer service, quality undercoating materials, and a comfortable, welcoming experience from start to finish, NH Oil Undercoating is the place to go! I highly recommend them! I will be a long time new customer.
