Rustproofing Ireland
Rustproofing a car in Ireland means more than a spray-can and a prayer. Rayco rustproof cars, 4x4s, vans and commercials by treating the metal first, welding out anything already rotten, then applying a heavy-duty coating designed to keep working for years on Irish roads.
What professional rustproofing gives you
DIY rustproofing kits are cheap for a reason — they usually skip the prep. A proper job treats what's already rusting instead of just coating over it.
- Full underside treated, not just easy-to-reach panels
- Rust removed and treated before any coating is applied
- Welding available if rot has already gone through metal
- Coating reaches into seams, box sections and cavities
- Suits older vehicles as well as new purchases
- Cars, 4x4s, vans, jeeps and commercial fleets covered
- Up to 7 year warranty on the coating
- Improves resale value and NCT prospects
Our rustproofing process step by step
Every vehicle goes through the same disciplined process, whether it's a small hatchback or a commercial van.
- 01
Book & Inspect
You book in, we put the vehicle on the ramp and inspect the chassis, sills, arches and floor pans.
- 02
Wash & Strip Back
Old underseal, mud and grease are pressure-washed and degreased so we can see the actual metal condition.
- 03
Treat Any Rust Found
Corrosion is mechanically removed and neutralised — nothing gets sealed over active rust.
- 04
Weld If Required
Where rust has already eaten through, we weld in new metal to NCT standard before moving on.
- 05
Apply Rustproofing Coating
A heavy-duty rustproof coating is sprayed into every cavity, seam and rail, not just the flat panels.
- 06
Final Check & Warranty
We check coverage, hand over warranty details and advise on any follow-up if needed.
What we rustproof
Rustproofing isn't one-size-fits-all — different vehicles need different levels of prep and coating.
New & Nearly-New Cars
Getting ahead of rust before it starts is far cheaper than repairing it later, especially on cars kept long-term.
Older Cars & High Mileage
Vehicles that already show surface rust get treated properly before any coating goes on.
4x4s & Jeeps
Off-road and rural vehicles that see mud, water and salted roads need heavier duty coverage.
Vans & Commercial Fleets
Fleet vehicles that clock up mileage fast benefit from scheduled rustproofing to protect resale value.

Rustproofing Is Prevention, Not a Cure
Rustproofing works best as prevention — applied before rust takes hold, or immediately after existing corrosion is properly treated. Once metal has thinned or perforated, welding becomes part of the job before any coating can do its work.

Common questions about rustproofing in Ireland
+Is rustproofing the same as undersealing?
They overlap but aren't identical — undersealing is one method used to rustproof a vehicle. Rustproofing is the broader goal, achieved through cleaning, rust treatment, welding where needed and a protective coating.
+How much does rustproofing cost in Ireland?
Cost depends on vehicle size and condition. Send WhatsApp photos of the underside and we'll quote honestly before you book in.
+Is it worth rustproofing an older car?
Yes, provided the metal isn't too far gone. We treat existing rust and weld where needed first — rustproofing over already-rotten metal just hides the problem temporarily.
+How long does rustproofing take?
Most rustproofing jobs are completed in a day. If welding is needed first, it can take a few days depending on how much metal has to be replaced.
+Do you rustproof 4x4s and vans?
Yes — 4x4s, jeeps, vans and commercial vehicles make up a large part of our daily work, given how much exposure they get to mud, water and salt.
+Does rustproofing help with the NCT?
Treating and welding corroded structural areas before sealing them reduces the risk of NCT failure related to rust, though the NCT itself assesses the vehicle on the day.
