Vehicle underbody and chassis after dry ice blasting

Dinitrol, prepared with dry ice

Dry Ice Prepared Dinitrol Treatment

The full Dinitrol system, applied to a dry ice blasted underbody. Professional preservation for vehicles you intend to keep.

Built on dry ice blasting

A professional system deserves professional preparation

Dinitrol is a professional rust prevention system, combining underbody protection with cavity treatment. It is a preservation programme, not a single coating.

The system performs best on clean, dry metal. We prepare every vehicle with dry ice blasting, lifting road film, old wax and failing coatings without abrasion or moisture. Each CO₂ pellet sublimes on impact, so the Dinitrol goes onto a surface with nothing left to undermine it.

Applied to a properly prepared vehicle and maintained with annual inspection, a full Dinitrol system offers around five years of protection.

Who it suits

Why Dinitrol, and who it suits

A full system for owners who want long-term preservation and are happy to keep it maintained.

Underbody and cavities

Protection that reaches inside sills, box sections and chassis members, as well as the exposed surfaces.

Built for the long term

Suited to classics, restorations and vehicles kept for years, where the investment in preparation pays back.

Maintained, not forgotten

Annual inspection keeps the system working. We record your interval and, with your permission, remind you when it is due.

The process

How we apply the Dinitrol system

Every vehicle is assessed individually. This is not a car wash and not a valet service.

  1. 01

    Assess

    Condition, use and storage reviewed. Scope agreed with you first.

  2. 02

    Dry ice preparation

    Underbody, chassis and arches dry ice blasted to clean, dry metal.

  3. 03

    Inspect

    Any corrosion addressed before the system goes on. Repair arranged where needed.

  4. 04

    Apply the system

    Underbody protection and cavity treatment applied as a full programme.

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.

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.

Around five years, when the system is inspected and maintained annually. This is a maintenance interval, not a warranty.
