Local conditions in Armagh

Why Irish vehicles corrode early
Two things drive corrosion here: constant damp and winter road salt. Salt keeps steel wet for far longer than rain alone would, and because it is carried up into box sections and cavities it works on the parts of the vehicle nobody looks at.
Coastal counties add salt-laden air on top of that, so vehicles that never see a gritted road can still corrode from the underside up.
Underbody versus cavity treatment
Underbody coating protects the exposed surfaces you can see and reach — rails, floor pans, arches and mounts. Cavity treatment deals with the inside of box sections and sills, where rot usually starts and where an external coating can never reach.
The underside is cleaned back, dried and inspected first, then the protective coating is applied to the chassis, floor pan, sills, arches and mounting points, with cavity sections treated where access allows.
Protection is not a repair
Rust protection is preventative. Where corrosion has already eaten through structural steel, the honest answer is that the section needs cutting out and welding before any protective treatment is worth applying. We will tell you which of the two you are actually looking at.

Armagh rust protection FAQs
Do you do rustproofing for Armagh vehicles?
Yes — owners travel to the Rayco yard from Armagh and nearby counties for rust protection work. WhatsApp photos to 087 919 2193 and we'll price it first.
What's the difference between undersealing and rustproofing?
Undersealing is the coating applied to the exposed underside. Rustproofing is the wider job, including treating inside box sections and cavities where corrosion usually begins.
How often should rust protection be redone?
It depends on the product used, the mileage and how much salt the vehicle sees. An annual underbody inspection tells you whether a top-up is needed rather than guessing.
Can rust protection be applied to a working farm or contractor vehicle?
Yes. Those vehicles usually need more cleaning first, because packed mud and slurry have to come off before anything is applied.
