The enemy is underneath
UK road salt is quietly rotting your vehicle
Gritted winter roads, damp lanes and salt spray attack the metal you never look at — the sills, arches and chassis. By the time rust shows, it's often MOT-failure territory. The fix is simple: treat it early, treat it properly, and keep it protected.
- Mechanical rust removal back to sound metal
- Wax injected inside the hidden cavities
- Sealed with a tough, lab-proven top coat
- Before & after video so you see the result

Why Mobile Rust Doctor
Clinical precision. Workshop grit.
Four things that set us apart from a quick spray-and-go.
Lab-proven materials
We use Bilt Hamber Dynax UB, tested in ASTM-B117 salt-spray chambers — tougher and longer-lasting than lanolin-based products (e.g. Lanoguard).
Cavity injection included
Rust starts inside the sills, arches and chassis. We inject wax where it actually begins — not just where you can see.
We come to you
No garage drop-off, no waiting room. We treat your vehicle on your own driveway, anywhere in our coverage area.
Proof on every job
You get a before and after video of the underside, so you can see exactly what was done.
See the difference
From surface rust to fully sealed
This is the transformation we film for every customer — a rusty, exposed underbody, then the same parts de-scaled, wax-injected and fully sealed against the salt.
