What RPNI does
An independent network with a clear record.
RPNI is an independently operated rust-protection network, building Ireland-wide coverage from its first Approved Centres. RPNI trains and assesses participating garages, maintains treatment records and administers its own rust-protection programme.

Use the certificate number and vehicle registration shown on the issued record.
Verify a treatment certificate →Independent and privately operated. RPNI is not a government body, statutory regulator, insurer or NCT affiliate.
Protection for Irish conditions
Rust starts where you cannot see it.
Atlantic moisture, road salt and hidden seams create the ideal conditions for corrosion. Treatment by a trained applicator reaches the underbody and cavities before damage becomes expensive.
Salt.
Damp.
Hidden seams.
Protection is applied where moisture collects: cavities, joints, wheel arches and exposed underbody areas.
Protect the
metal beneath.
Corrosion prevention helps preserve the vehicle’s body, mounting points and hard-to-repair structural areas.
A treatment
history that stays.
Your numbered RPNI certificate creates a record that can be checked by an owner, buyer or Approved Centre.
Professional treatment
Prepared carefully. Applied thoroughly.
The documented process combines proper preparation, access to hidden areas and products selected for cavities, seams and exposed underbody surfaces.
Product images show examples from the Mercasol range. RPNI Approved Centres use appropriate Mercasol or Noxudol systems selected for each vehicle.
Before & after

Keep the protection.
A clear look at vulnerable metal before treatment and the protected finish afterwards. RPNI-approved applicators use Mercasol or Noxudol corrosion-protection systems selected for the vehicle, its cavities and exposed underbody surfaces.

Renewable protection programme
Up to 16 years
Built around two-year inspections.
Eligible vehicles may receive a two-year renewable rust-protection warranty, subject to eligibility, owner-care requirements and inspection every two years, up to a maximum total period of 16 years.
- Eligibility first. Vehicle age, condition and preparation requirements must be assessed before cover is offered.
- Inspection every two years. Renewal depends on the vehicle returning on schedule and any required maintenance being completed.
- Maximum total period. Sixteen years is the programme limit, not an automatic warranty issued with every treatment.
Full eligibility, owner-care and warranty terms will be published before the programme launches.
Your route to protection
Three steps. No guesswork.
Start with a local RPNI Approved Rust Protection Centre, keep your certificate, and return on schedule when the next inspection is due.
