Rust does not happen all at once. It starts in the places you do not see, inside frame rails, behind wheel wells, along seams and joints where road salt, brine, and moisture sit for months at a time. By the time it shows up on the surface, the damage underneath is already well ahead of it.
Professional undercoating and cavity protection give your vehicle a real defense against the salt, sand, and chemical de-icers that Minnesota roads are treated with from late fall through early spring. Whether you are protecting a new vehicle before its first winter or stopping corrosion from spreading on a daily driver with a few years on it, the right product applied to a properly prepared surface can add years of life to the undercarriage and preserve resale value in a climate that works against both.
We offer two undercoating options depending on your vehicle’s condition and what makes sense for how you drive: a permanent hard shell coating built for long-term chip and corrosion protection, and Woolwax, a penetrating wax-based treatment that creeps into hidden areas and protects against every ice control agent on the road today.

It depends on the type of undercoating. We offer two options, and they are designed for different situations.
Our permanent hard shell coating can last up to a lifetime, with touch-up recommended every five to six years to maintain full coverage. It was originally developed as a chip guard for trailer trucks, so it is built to take a beating. It adheres exceptionally well to new steel, works on slightly rusted vehicles, and doubles as a sound deadener. It is also excellent for high-wear areas like wheel wells. Because this coating is permanent and non-removable, it performs best on vehicles with new or minimal rust where the surface does not need further treatment underneath. Used vehicles are pretreated with a salt and brine remover before application.
Woolwax takes a different approach. It lasts up to three years, with an inspection and touch-up or recoat recommended after two. Rather than forming a hard shell, Woolwax remains active throughout its lifespan. It creeps and migrates into hidden areas, seams, and joints that a rigid coating cannot reach, and it is self-healing, meaning minor disruptions in coverage reseal on their own. Its corrosion inhibitors were developed specifically to protect vehicle undercarriages against road salt, liquid calcium chloride, brine, and the other ice control agents that Minnesota roads see from October through April. Woolwax works well on both new and used vehicles, and all used vehicles are pretreated with a salt and brine remover before application.
The right choice depends on the vehicle’s age, its current condition underneath, and whether the owner prefers a permanent solution or a product that gets into every hidden space and is reapplied on a regular schedule.

Our Testimonials
Woolwax® is a lanolin (wool-wax) based, solvent free corrosion preventive designed for use on any known metal. Woolwax® has a thixotropic viscosity that allows for a thick and drip free coating. Woolwax® leaves a soft, grease-like self-healing film that can be applied by brush or spray applicator gun. Woolwax® will not dry out and will penetrate metals to the base, providing corrosion protection in highly corrosive atmospheres like those found in industrial or environmental settings.
Yes, and a new vehicle is actually the best time to do it. The steel underneath is clean, free of rust, and has not yet been exposed to the road salt, brine, and chemical de-icers that start breaking down unprotected metal during the first winter. Applying undercoating before that exposure begins means the coating bonds to a clean surface and provides protection from day one rather than trying to slow down damage that has already started.
It is important to consider where you decide to get the undercoating. If you choose to get it at the time of purchase at the dealership, you’re probably going to be charged quite a bit more than if you were to go to a local Minnesota detailer for undercoating services.
It depends on how far the rust has gone. Light surface rust is generally fine, especially with proper cleaning and pretreatment with a salt and brine remover before application. Woolwax is a particularly good option for vehicles with some existing corrosion because it creeps into seams and hidden areas where rust tends to start and remains active against moisture and salt throughout its lifespan.
Heavy rust with flaking metal, structural damage, or holes is a different situation. At that point, the underlying metal needs repair before any coating can do its job effectively. New or minimal rust always produces the best results.

During winter, rinse the undercarriage every couple of weeks to keep road salt and brine from sitting against the coating. A touchless wash with an undercarriage rinse works well. Once salt season ends, do a thorough undercarriage wash to clear out whatever accumulated over the winter months.
Schedule an annual inspection to catch any areas where coverage has worn thin from road debris or gravel, and touch those spots up before the next winter.
Woolwax typically needs a recoat every two to three years. Permanent hard shell coatings usually only need touch-ups every five to six years.
