Waxoyl Treatment & Premium Underseal — Ireland
Looking for Waxoyl in Ireland? Rayco apply premium heavy-duty underseal as a professional Waxoyl alternative — tougher, longer-lasting and built for Irish road salt, damp and country lanes. Cars, 4x4s, vans and commercials.
Why customers choose our underseal over DIY Waxoyl
Waxoyl (sometimes spelt waxoil) is a household name for rust protection — but DIY application over a dirty or rusted chassis simply traps moisture and accelerates corrosion. We strip, treat and prepare the chassis properly, then apply a premium heavy-duty underseal that outlasts traditional wax coatings on Irish roads.
- Full chassis pressure-clean & degrease
- Intense rust treatment before any coating
- Chassis welding where structurally needed
- Premium heavy-duty underseal (Waxoyl-grade or better)
- Up to 7 year warranty
- Professionally applied — no missed seams

Common questions about Waxoyl in Ireland
+How long does Waxoyl last?
DIY Waxoyl and similar wax-based products typically need a top-up every 1–2 years on Irish roads. Our professional heavy-duty underseal carries up to 7 years warranty when applied over a properly prepped chassis.
+How much does it cost to underseal a car in Ireland?
Most cars come in between €350 and €900 depending on size, chassis condition and whether welding or rust treatment is needed first. Send WhatsApp photos of the underside and we'll quote before you book in.
+Will Waxoyl kill rust?
No — Waxoyl does not stop active rust on its own. If you spray it over flaking, rusted metal you trap moisture and accelerate corrosion. We strip back rust, treat the metal and weld where needed before any coating goes on.
+How do you apply Waxoyl / underseal the right way?
Vehicle on the ramp, full pressure-clean and degrease, rust treatment, structural welding where needed, then premium underseal sprayed into every chassis rail, seam, cavity and box section. No shortcuts.
+Is underseal better than Waxoyl?
Modern professional underseal coatings are tougher, more abrasion-resistant and last significantly longer than traditional wax. For Irish road salt, damp and country lanes, professional underseal is the more durable choice.
+Do you treat 4x4s, vans and commercials?
Yes — Land Cruiser, Hilux, Ranger, Defender, Land Rover, Jeep, vans and commercial fleets are core to what we do. Same process, scaled to the vehicle.
