Anti-Corrosion Treatment Ireland
Corrosion doesn't need much of a foothold — a chip in factory paint, a worn seam, or a scratch from a stone is enough to start it. Rayco provide anti-corrosion treatment that removes what's already there, welds out anything structurally compromised, and applies a protective coating to stop it coming back.
What anti-corrosion treatment achieves
Corrosion left alone spreads from small chips into larger structural problems. Treating it early is always more cost-effective than repairing the damage later.
- Existing corrosion removed, not just coated over
- Bare metal neutralised before any sealant is applied
- Structural welding available where corrosion has perforated metal
- Coating protects seams, cavities and panel joints
- Reduces long-term repair costs from spreading corrosion
- Works across cars, 4x4s, vans and commercial fleets
- Up to 7 year warranty on coatings applied
- Supports resale value and NCT outcomes
How we treat corrosion
Anti-corrosion treatment follows the same core steps whether the vehicle has light surface corrosion or advanced structural rot.
- 01
Inspect on the Ramp
The vehicle is raised so we can see exactly where corrosion has started and how far it has spread.
- 02
Clean & Degrease
The affected areas are pressure-washed and degreased to expose the true state of the metal.
- 03
Remove & Treat Corrosion
Corroded metal is mechanically stripped back and chemically treated to neutralise it before moving on.
- 04
Weld Structural Damage
Where corrosion has already gone through the metal, we weld in fresh sections to NCT standard.
- 05
Apply Protective Coating
A heavy-duty coating is applied to seal treated areas and prevent moisture reaching the metal again.
- 06

Where corrosion typically develops
Corrosion tends to concentrate in the same vulnerable areas across most vehicles — we focus treatment there first.
Chassis Rails & Sills
Structural areas that carry road salt spray and rarely get cleaned underneath.
Wheel Arches & Wing Edges
Areas exposed to constant grit, stone chips and moisture thrown up by the tyres.
Floor Pans & Boot Floors
Sections that trap moisture from carpets, leaks or wet cargo over time.
Vans & Commercial Load Areas
Load floors and rear doors exposed to whatever cargo and weather conditions bring in.

Corrosion Spreads Faster Than It Looks
A small patch of surface corrosion can look manageable while it's actually undermining the metal around it. Left untreated through even one more winter of Irish road salt, what started as a cosmetic issue can become a structural repair — treating it early keeps the job smaller and cheaper.

Common questions about anti-corrosion treatment
+What is anti-corrosion treatment?
It's the process of removing existing corrosion, neutralising the bare metal underneath, welding out any structurally weakened sections, and applying a protective coating to prevent it returning.
+Is anti-corrosion treatment the same as rustproofing?
They describe closely related goals — both aim to stop metal degrading over time. Corrosion is the broader chemical process; rust is corrosion specific to iron and steel, which is what most vehicles are treated for.
+How much does anti-corrosion treatment cost in Ireland?
Cost depends on how far corrosion has progressed and the size of the vehicle. Send WhatsApp photos and we'll quote before you visit.
+Can corrosion be treated without welding?
If it's surface-level, yes — mechanical removal and a protective coating are enough. Once corrosion has perforated structural metal, welding is needed before any coating can be effective.
+How long does an anti-corrosion coating last?
Our heavy-duty coatings carry up to 7 years warranty when applied over properly treated metal, considerably longer than basic DIY corrosion sprays.
+Do you treat corrosion on vans and 4x4s as well as cars?
Yes — vans and 4x4s often show more advanced corrosion due to mileage and exposure, and are a regular part of our daily work.
