Rustproofing and Undercoating Specialists in Somersworth, NH

Get the best layer of defense against snow, salt, and rust

Your Undercarriage's First Line of Defense Against Snow and Salt

When people think about keeping a clean vehicle, they immediately think about the paint correction or an interior detail. And for many car owners who don’t live around New Hampshire or Maine, that’s all they need to worry about. But for those that go through the snow and salt seasons, you also need to protect the underside of your car that’s just as critical, or even moreso, than the paint or interior.

Our professional undercoating helps block out moisture, salt, and other corrosive elements that can eat away at your vehicle’s frame which helps to extend its life and preserve its value.

What’s The Difference Between Rustproofing and Undercoating?

Do you need one or the other? Should you get both? Is it even worth it? If you’ve ever wondered whether rustproofing or undercoating is right for your vehicle, you’re not alone. We get this question all the time. The answer depends on where you live and what you go through, but for us, where winter brings plenty of snow, ice, and road salt, it’s an easy decision to make.

First, it’s important to understand what each service does. The goal of rustproofing and undercoating is to help prevent corrosion from the natural process that begins when metal is exposed to moisture and oxygen. Newer vehicles offer some factory protection, but it wears off over time and that means you’re leaving your car vulnerable to rust, especially during harsh winters.

We can’t avoid rust. It’s a problem we’re all going to face as we drive. But you can be proactive about it and make sure you’re protecting your vehicle against it. While some areas of your car can be easily protected, others parts remain completely exposed and prone to rust. That’s where combining rustproofing and undercoating really makes sense.

Rustproofing targets hard-to-reach spots inside the vehicle’s panels, while undercoating defends the underside from salt, gravel, and moisture. To get the best of both worlds, don’t think of them as separate solutions, but rather, a proactive combination to give you the best layer of defense. Together, they offer complete protection.

Rustproofing and Undercoating FAQs

What is rustproofing?
Rust proofing targets specific areas of your vehicle where rust is most likely to start like the fenders, tailgates, and other moisture-prone spots. It’s applied using a protective wax that reaches tight spaces where rust tends to take hold. This treatment is ideal for preventing rust in vulnerable, hard-to-reach areas that often get overlooked.

What is undercoating?
Undercoating is a full-body defense for the underside of your vehicle. It involves spraying a wax or rubber-based coating across the undercarriage, including the frame, wheel wells, and floorboards. This helps shield your vehicle from road salt, water, mud, and debris kicked up while driving. Even though the underbody isn’t visible, it takes a daily beating and is highly susceptible to corrosion.

What’s the best time to get this done?
The best time to get undercoating done is in the spring or early fall. This allows your vehicle to be treated before or after the harshest winter conditions, giving it a strong barrier against road salt, moisture, and grime.

Can undercoating be done if there’s already some rust on the vehicle?
Yes, undercoating can still be applied if your vehicle has light surface rust. In fact, some products are designed to bond to rusted areas and help slow down further corrosion. However, if there’s heavy rust or structural damage, additional prep work will be needed.

Can you do the service if I don't have a garage?
Absolutely. Many undercoating services are mobile and can be done at your home or workplace as long as there’s enough space to work and the weather allows.

Is this a permanent treatment, or will I need to redo it each year?
Undercoating is not permanent and typically needs to be reapplied every 12 to 18 months, depending on driving conditions. Annual maintenance helps ensure the coating stays effective, especially in Maine’s harsh winters.
