Dynax-UB, prepared with dry ice
Dry Ice Prepared Bilt Hamber Dynax-UB
Bilt Hamber Dynax-UB, applied to a dry ice blasted underbody. Durable wax-based protection for classics and cars in regular use.
Built on dry ice blasting
Wax-based protection, properly prepared
Dynax-UB is a wax-based underbody protection from Bilt Hamber. It forms a durable, flexible film designed to keep moisture and road salt off the metal.
Like any coating, it is only as good as the surface it is applied to. We prepare with dry ice blasting: contamination, road film and failing coatings lifted without water, abrasion or chemicals. Each CO₂ pellet sublimes on impact, leaving a clean, dry substrate for the Dynax-UB to bond to.
The result is a pragmatic, mid-term protection with a typical interval of around two years.
Who it suits
Where Dynax-UB makes sense
A practical choice for cars that are driven and enjoyed.
Daily-use classics
Durable enough for regular use and winter roads, without the commitment of a full preservation programme.
Weekend cars
Sound protection for cars that see seasonal use and spend the rest of the year stored.
A practical middle ground
Longer between applications than an annual lanolin treatment, simpler than a full system.
The process
How we apply Dynax-UB
Every vehicle is assessed individually. This is not a car wash and not a valet service.
- 01
Assess
Vehicle, use and storage reviewed. Dynax-UB confirmed as the right fit.
- 02
Dry ice preparation
Underbody and arches dry ice blasted to clean, dry metal.
- 03
Inspect
Corrosion addressed before anything is covered. Repair arranged where needed.
- 04
Apply Dynax-UB
Applied evenly across the underbody, arches and exposed chassis.
Corrosion protection
Four systems, one foundation
Protection applied to bare, contaminant-free metal bonds harder and lasts longer than the same product laid over road film. We hold four systems in-house and recommend by vehicle, storage and goal, rather than leading with one product.
Lanoguard Clear
Short-term protection, reapplied annually. Suited to vehicles in active use or stored outdoors.
Bilt Hamber Dynax-UB
Wax-based protection. The pragmatic choice for daily-use classics and weekend cars.
Dinitrol Full System
A professional preservation system, applied as part of a full programme, with annual inspection and maintenance.
Longest-lastingCeramic Underbody Coating
The long-term option for high-value vehicles, maintained by annual inspection.
Each system has a recommended maintenance interval. We record yours and, with your permission, remind you when it is due, much like an MOT. Protection periods are maintenance intervals, not warranties.

Questions
Frequently asked questions
How long does Dynax-UB last?
Around two years as a typical maintenance interval, depending on use and storage. This is not a warranty.
Dynax-UB or Lanoguard?
Lanoguard stays soft and is refreshed annually. Dynax-UB forms a firmer wax film and lasts longer between applications. We recommend after assessing the car and how it is used.
How is the vehicle prepared?
On a lift, with wheels and undertrays removed where access requires it, and dry ice blasted to clean, dry metal before any product is applied.
Is Dynax-UB suitable for a classic?
Yes. It is a common choice for classics in regular or seasonal use.
