Paintwork protection
Protective sheeting and masking reduce overspray and keep sensitive areas clear.
Rust proofing Wales
Our underside rustproofing treatment is built for long-lasting protection, not a quick cosmetic coat. Preparation, layered underseal, cavity wax and quality control all matter.
Thorough underside underseal protection
Once preparation and any rust repairs are complete, the vehicle should have a clean, dry, solid surface ready to treat. That is when the rust proofing process starts.
The treatment covers the underside up to the inner sill edge and the inside lip of each wheel arch. Hidden cavities are treated separately with heated wax injection.
- Designed for cars, 4x4s, classics, campers, vans and imports.
- Applied after cleaning, rust removal, conversion and drying.
- Backed by warranty paperwork and annual inspection requirements.
Our rust proofing process
The exact approach varies by vehicle condition, but this is the typical sequence after preparation is complete.
Undercoat layer
An initial coat is applied for even coverage across the prepared underside.
Main coat layer
A heavier second application builds the main protective underseal film.
Top coat layer
A final layer completes the coating and leaves the underside protected.
Cavity wax injection
Heated wax is injected into cavities to help protect hidden seams and channels.
Drying time
Heat lamps and drying time are allowed between layers and before collection.
Quality control
The vehicle is checked before the sheeting is removed and the finish is cleaned.
Photos and paperwork
Process photos, invoice, warranty certificate and service record are prepared for your records.
Warranty and annual inspection
Rust proofing treatments are guaranteed for five years subject to annual inspection and fair usage. Annual inspections allow us to check for damage, top up cavity wax and keep the protection doing its job.
If you use the vehicle off-road, near saltwater, through winter salt, or on rough tracks, the annual inspection becomes especially important because damaged underseal needs attention quickly.
