FAQs

Have questions about underbody protection, treatments, or our process? You’re in the right place.

  • Our industrial-grade protection systems are designed to last 10+ years, thanks to multi-layer coatings including glass flake epoxy primer, 2K top coats, and graphene-infused clear coats. For those opting for Dinitrol, treatments typically offer 3–5 years of reliable coverage.

  • Most underseals are bitumen-based and prone to cracking, trapping moisture, and hiding corrosion. Our system uses industrial epoxy paints and advanced application techniques, giving your vehicle long-term, visible, and breathable protection – no flaking, no shortcuts.

  • Absolutely. Prevention is always better than cure. Treating a vehicle from new means locking out moisture and road salt from day one, helping it stay rust-free for decades. We offer clear and invisible options if you want protection without changing the factory finish.

  • Cavity wax is injected into internal areas of your vehicle – places where corrosion often starts unseen. Using 360° wands and specialist sealing guns, we protect box sections, sills, pillars, and inside doors from internal rust. This is an essential part of full vehicle preservation.

  • We work on a wide range, including:
    - 🚗 Classic cars and imports
    - 🚙 4x4s and off-roaders
    - 🚐 Campervans and motorhomes
    - 🚛 Commercial and fleet vehicles
    - 🆕 Brand-new vehicles looking for long-term protection

  • Each vehicle goes through a detailed multi-step process:

    1. Full inspection and strip-down

    2. Dry ice or media blasting

    3. Epoxy priming and top coating

    4. Application of clear coat

    5. Cavity wax injection

    6. Final quality check and customer walkthrough

  • Most underbody treatments take 5 days, depending on the vehicle type and the level of rust or previous coatings to be removed. We’ll give you a clear timescale upfront during your consultation.

  • Use our Contact Page to send us your vehicle details and we’ll be in touch to arrange an inspection. Prefer to talk? Call us directly – we’re happy to help.
