Chassis Protection Ireland
A chassis is only as strong as its weakest rusted section — and once rot sets into rails, outriggers or crossmembers, wax alone won't fix it. Rayco provide chassis protection built on treating and welding what's already damaged, then sealing the whole frame with a heavy-duty wax-based coating.
What chassis protection actually delivers
The chassis is structural — it's what everything else bolts to. Protecting it properly means more than spraying wax into visible gaps.
- Rails, outriggers and crossmembers treated for rust
- Structural welding available for perforated sections
- Wax-based coating reaches deep into box sections
- Reduces risk of NCT failure from chassis corrosion
- Protects jacking points and body mount areas
- Suits 4x4s, vans, cars and commercial chassis
- Up to 7 year warranty on coating applied
- Maintains structural integrity for longer
How we protect a chassis
Chassis protection follows the same disciplined sequence every time, scaled to how much damage is already present.
- 01
Chassis Inspection
The vehicle goes up on the ramp so we can check rails, outriggers, crossmembers and jacking points thoroughly.
- 02
Clean & Strip
Mud, grease and old coatings are pressure-washed off so the true condition of the chassis is visible.
- 03
Rust Treatment
Surface corrosion is mechanically treated before any welding or coating takes place.
- 04
Welding Rusted Sections
Rails, outriggers and crossmembers with perforated metal are cut out and welded to NCT standard.
- 05
Wax-Based Chassis Coating
A heavy-duty wax-based coating is sprayed into rails, box sections and every accessible cavity.
- 06
Final Check & Warranty
Coverage is checked and warranty details are provided before handover.
Chassis types we protect
Different chassis designs need different attention — ladder-frame 4x4s in particular need thorough coverage.
Ladder-Frame 4x4s
Land Cruiser, Hilux, Defender, Ranger and similar vehicles with box-section chassis rails prone to internal rust.
Monocoque Cars
Cars where the chassis and body are one structure, with sills and floor pans acting as load-bearing sections.
Vans & Commercials
Chassis rails on vans and light commercials that carry loads and see heavy daily use.
Trailers & Towed Equipment
Chassis frames that sit exposed to road spray and weather for long periods between uses.

Chassis Rust Often Hides From View
Rust inside a box-section chassis rail can eat away at the metal for years before it's visible from outside. By the time a bulge, flaking paint or a hole appears, the internal damage is usually more advanced than it looks — which is why regular chassis inspection matters as much as the coating itself.

Chassis protection often follows welding repairs or NCT rust findings — see related pages below.
Common questions about chassis protection
+What is chassis protection?
Chassis protection is the process of treating rust on structural rails, outriggers and crossmembers, welding out any perforated metal, and sealing the frame with a heavy-duty wax-based coating to keep moisture and salt out.
+Is chassis wax protection better than underseal?
Wax-based coatings penetrate deep into box sections and rail interiors well, while underseal is often used on flatter, more visible panels. We use whichever coating suits the specific chassis area being treated.
+How much does chassis protection cost in Ireland?
It depends on chassis condition and whether welding is needed. Send WhatsApp photos of the chassis and we'll give you an honest quote before you visit.
+Can chassis protection stop existing rust from getting worse?
Coating over active rust without treating it first traps moisture and speeds up corrosion. We remove and treat rust — and weld where needed — before any protective coating goes on.
+Do you protect the chassis on 4x4s like Land Cruiser and Hilux?
Yes — ladder-frame 4x4s are a large part of our daily work, since their box-section rails are especially prone to rust developing from the inside out.
+Will chassis protection help with an NCT re-test?
Welding out corroded structural sections and properly sealing the chassis addresses the underlying issue an NCT tester would flag, though the retest itself assesses the vehicle independently.
