Water doesn't touch it.
Water causes rust. ChassisKeep keeps water out. Our treatment coats exposed metal with a moisture-resistant barrier designed to repel water, salt, and road grime even in the places you can't see.
Mobile undercoating that protects your vehicle's foundation.
ChassisKeep is a mobile vehicle undercoating and chassis preservation service. We bring a technical unit to your location and apply an oil-based corrosion barrier directly to your vehicle's undercarriage — sealing the frame, floor pans, and wheel wells against road salt, moisture, and time.
Unlike hard rubberized coatings that can crack and trap moisture, our oil-based undercoating stays flexible and self-healing. It creeps into seams and crevices, displaces water, and bonds to bare metal to slow rust before it starts. The result is a continuous protective barrier that keeps daily drivers, trucks, and fleet vehicles on the road longer.
Salt & Moisture Barrier
An oil-based undercoating penetrates seams and crevices to displace water and form a self-healing film that blocks road salt, brine, and moisture from reaching bare metal.
Frame & Chassis Protection
The coating bonds to the undercarriage, rocker panels, and frame rails — the areas most exposed to corrosion — without trapping existing moisture the way hard waxes can.
On-Site Deployment
A mobile technical unit comes to your home, office, or fleet yard. No drop-off, no waiting room — the service is applied where your vehicle already sits.
Annual Maintenance
Corrosion prevention is ongoing. An annual check-up restores the barrier where it has worn and inspects treated surfaces for early signs of rust.

Frequently asked questions
What is mobile vehicle undercoating?+
Mobile undercoating is a corrosion-prevention service where an oil-based barrier is sprayed onto your vehicle's undercarriage at your location. It seals the frame, floor pans, and wheel wells against salt, moisture, and road grime.
How does oil-based undercoating differ from hard wax or rubberized coatings?+
Oil-based coatings stay flexible and self-healing. They creep into seams and crevices and never crack or trap moisture against the metal. Hard coatings can chip and trap water, which can accelerate rust underneath.
Which vehicles benefit most from undercoating?+
Any vehicle driven in winter conditions or near the coast benefits. Trucks, SUVs, and fleet vehicles that stay on the road for years see the greatest return, since the barrier slows corrosion across a long service life.
How often should I reapply the undercoating?+
We recommend an annual check-up. The coating is inspected, and worn areas are refreshed so the barrier stays continuous year after year.
What areas does ChassisKeep serve?+
ChassisKeep deploys to counties across the Northeast. View the live service map for current coverage, and contact us if your county is not yet listed.
Do I need to bring my vehicle anywhere?+
No. The service is fully mobile. The technical unit comes to your home, office, or fleet yard and applies the undercoating on-site.
