Rust doesn't wait. Bought a truck in Pennsylvania or moved down from Chicago? Vehicles from salt states arrive in Arizona already corroding underneath — dry desert air slows it, but never stops it. We deep-clean the underbody with dry ice, neutralize the rust that's there, and seal it under a fresh layer of wax undercoating so your vehicle stays road-ready for years. Preserve your investment from the ground up.
Arizona doesn't salt its roads — but the vehicle you bought in Ohio, Michigan, New York or Pennsylvania spent years driving through it. The rust that started there keeps working underneath, and every monsoon season, car wash and cross-country road trip feeds it.
Road salt and brine pack into frame seams, pinch welds, spring perches and inside boxed rails, and keep pulling moisture out of the air long after the vehicle leaves the rust belt. Monsoon season finishes the job. We shield the underbody from moisture and salt — the two things that feed rust.
Undercoating sprayed over grease, scale and loose rust peels within a year and traps moisture underneath. The surface has to be clean, dry metal first — that's the part most shops skip, and the part we do with dry ice.
Pressure washing before coating drives water into the very seams you're trying to seal. Dry ice sublimates on contact — the metal is clean and dry the moment we're done, and nothing is sealed in.
Wax undercoating dampens road noise and vibration coming up through the floor pans and wheel wells. Owners notice it on the first drive — especially in trucks and older vehicles.
The underside comes back with a clean, even OEM-style satin finish. Before it's coated you see exactly what condition the frame, floors and suspension are in — so you know what you actually bought.
A clean, treated, properly coated undercarriage is the first thing an Arizona buyer or inspector looks at on an out-of-state vehicle. Protecting the structure now is far cheaper than repairing it later — and it shows at sale time.
Every image below is an actual Alpine job. This is what the metal looks like before any rust inhibitor or undercoating goes on.
Three steps, one visit. Each one only works because the step before it was done right.
We blast the entire underbody — frame, floors, suspension, wheel wells, inside the rails — removing road grime, grease, old failed undercoating and loose rust. No water, no chemicals, no disassembly, no residue. What's left is clean, dry metal.
A rust inhibitor is applied to every area showing oxidation. It penetrates the rust that's there, stops it from spreading, and creates a stable surface the coating can bond to — instead of sealing live rust underneath.
A new layer of wax-based undercoating (Dinitrol) is applied across the underbody, with cavity wax inside boxed sections where salt hides. It stays flexible, self-heals from small chips, and blocks moisture and salt from reaching the steel.
Three proven products, one non-negotiable first step: every job starts with a dry-ice deep clean, because no coating lasts on a dirty surface. We'll recommend the right product after we see the vehicle.
High-performance wax-based undercoating for lasting rust and corrosion protection. Our go-to for trucks, SUVs and daily drivers that came from a salt state — it stops what's started and seals the steel for years.
Lanolin-based rustproofing that stays wet and flexible instead of curing hard. Popular with overland and off-road owners who want protection they can see working, top up themselves, and re-apply after a hard season.
Clear nanotech ceramic coating that enhances shine and repels water and dirt. Built for new vehicles that need protection without changing the factory look, and for finished restorations you want to keep looking finished.
Old, cracked or peeling undercoating trapping moisture and hiding rust? We strip it with dry ice — no grinding, no chemicals, no damage to the steel — treat what's underneath, and re-coat with Dinitrol or WoolWax.
We can work with any make or model. Not sure which product fits? Text us a photo of the underbody and we'll recommend one.

Final price depends on vehicle size, how much rust and old coating we find, and the product you choose. Heavy structural rust or perforation is repair work, not coating — we'll tell you honestly if that's what you have.
It stops it. Dry ice removes loose and surface rust, and the inhibitor chemically neutralizes what remains so it can't keep spreading under the coating. Rust that has already eaten through metal (perforation) needs repair first — we'll show you exactly where you stand after the clean.
Pressure washing pushes water into the seams and boxed sections you're about to seal, and it doesn't remove grease or old failed undercoating. Dry ice lifts all of it and leaves the metal dry the moment we finish — so the inhibitor and coating bond to clean steel instead of sealing moisture in.
If your vehicle has always lived here, usually not. If it came from a salt state, yes — the salt is still in the seams, and monsoon humidity, car washes and road trips keep feeding it. Vehicles that travel to snow country in winter benefit as well.
Dinitrol is our standard: a penetrating ML rust remediation step followed by a 4941 wax coating that dries to a satin finish, protects inside the frame, and is a one-time application. WoolWax is lanolin-based — it stays wet and flexible, creeps into seams, and is easy to refresh yourself, which is why overland and off-road owners who take rock hits like it. Daily driver or work truck: Dinitrol. Rig that sees trails and gets re-treated every season or two: WoolWax. Either way the dry-ice clean comes first.
For new vehicles you want protected without changing the factory look, and for finished restorations. The clear ceramic coating keeps the mirror-like finish, repels water, dirt and brake dust, and makes the underside easy to keep clean. It is a protective finish, not a rust-remediation product — so if the vehicle arrived with rust, we treat that first.
Most trucks and SUVs are done in one day: dry-ice cleaning in the morning, inhibitor and coating in the afternoon. We're mobile across the Phoenix metro, or you can drop the vehicle at our Tempe shop.
Yes. Old rubberized or asphalt undercoating that's cracking traps moisture and hides rust. We strip it with dry ice, treat the metal underneath, and apply a fresh coating — no grinding, no chemicals, no damage to the steel.
We come to your garage, shop or storage facility — or bring the vehicle to our Tempe shop. Mobile rust protection throughout the Phoenix metro.
