Defense Against Salt & Winter Chemicals
WoolWax is designed to protect against road salt, liquid calcium chloride, brine, moisture, and other winter road treatments that accelerate corrosion.
WOOLWAX RUST PROTECTION
Undercoating
Long-lasting rust protection for Wisconsin roads, harsh winters, salt, brine, and everything your undercarriage gets put through.
WOOLWAX RUST PROTECTION
A Protective Barrier That Stays Active.
WoolWax is a thick, solvent-free, wool-grease-based corrosion inhibitor made specifically to protect automotive undercarriages.
Instead of drying into a hard shell, WoolWax stays soft and pliable. That allows it to continue working its way into seams, overlaps, frame sections, and other areas where moisture and corrosion like to hide.
We use it across the exposed underside of the vehicle and inside vulnerable cavities to create a more complete rust protection system — not just something that makes the frame look black.
What Makes WoolWax Different?
01
Solvent-Free
WoolWax doesn't rely on solvents that evaporate after application.
02
Thick & Wash-Off Resistant
Its heavy viscosity helps it stay on exposed underbody areas through rain, road spray, and harsh winter conditions.
03
Stays Soft & Pliable
It doesn't dry into a brittle coating that can chip or crack away.
04
Creeps Into Hidden Areas
WoolWax continues migrating into seams, folds, pinch welds, and difficult-to-reach areas after application.
BUILT FOR THE REAL WORLD
Why Rust Protection Matters Here
Wisconsin winters put the underside of your vehicle through a lot more than just snow.
Protection Where Rust Hides
Frames, rocker panels, seams, doors, and enclosed cavities can hold moisture where you can't easily see it. WoolWax can be applied into these areas instead of protecting only the visible underside.
Protect the Vehicle Underneath
Your frame, suspension mounting areas, body structure, brake and fuel-line areas, and underbody all live underneath the vehicle. Protecting that structure helps preserve the vehicle long-term.
Protection That Can Be Maintained
WoolWax is designed as a maintainable rust protection system. Worn exposed areas can be inspected and refreshed without stripping the entire existing coating and starting over.
THE GOAL IS SIMPLE
Keep Water, Salt & Winter De-Icers Off Of Your Frame.
Rust protection is much easier to stay ahead of than it is to repair once corrosion has taken over.
