Cleaning and drying
Start with dirt, oil and salt removal, then allow surfaces and seams to dry thoroughly.
WHAT WE DO
Eight stages. One principle: prepare before you protect.
A long-lasting underbody treatment is a system, not a single spray can. Frazer’s recommended approach uses preparation, targeted corrosion treatment, suitable primer and protective coatings where required. The stages are chosen after inspection and product compatibility is checked rather than applying every product to every vehicle.
Whether your priority is better appearance, inspection access or long-term corrosion protection, the first decision is always the right method for the surface. That includes recognising when metal repairs must take priority over a cosmetic result.

CORK VEHICLE CORROSION PROTECTION / TREATMENT STEPS
OUR PROPOSED LAYERED CORROSION-PROTECTION APPROACH
For damp Irish driving conditions, surface preparation and material compatibility matter more than the colour or thickness of underseal. The right treatment sequence is assessed per vehicle and the products selected. The steps below explain the approach we can discuss for rust treatment and underbody protection.
- Initial inspection: check exposed and hidden corrosion, existing coatings, seams, drains and any structural defects.
- Wash, degrease and remove salt: thoroughly clean suitable areas before rust removal or recoating.
- Dry and prepare: remove trapped moisture and use laser, mechanical or other surface preparation where appropriate.
- Repair damaged metal: perforated or structurally weak sections need suitable repairs, not a coating over the top.
- Prime and topcoat if specified: apply compatible corrosion-protection layers in line with the product data sheets and metal preparation requirements.
- Protect cavities: apply suitable cavity wax to reachable box sections and seams with an appropriate access plan.
- Finish, inspect and maintain: select an underbody wax or coating compatible with the prior layers; check coverage and advise periodic inspection.
Not every step or product belongs on every car. For example, wax systems and epoxy/topcoat systems can have different sequencing requirements. We avoid combining products without checking the manufacturer guidance.

PRACTICAL EXPERTISE
How a proper system comes together
Every vehicle, finish and component is different. We focus on the considerations that genuinely affect the outcome.
Corrosion preparation
Use suitable laser or mechanical methods for accessible rust, with repairs where metal integrity has been lost.
Compatible protection
Where needed, apply epoxy primer and topcoat, consider cavity wax for enclosed sections and finish with suitable underbody wax.
MORE THAN THE CLEAN
FROM ASSESSMENT TO A PROTECTED FINISH.
The visible result is only one part of responsible restoration. Before beginning we consider the substrate, corrosion severity, surrounding materials and practical access. Once cleaned, the surface may need immediate protection and, where appropriate, an inspection for hidden deterioration.
For underbodies and restoration work, this can involve degreasing, drying, accessible rust removal, compatible primer, topcoat, cavity wax and a suitable protective finish. Not every stage is needed on every job; the sequence is agreed after inspection.

STRAIGHT ANSWERS
GOOD QUESTIONS. CLEAR ANSWERS.
Is our corrosion protection process suitable for every vehicle or surface?+
No. Suitability depends on the material, condition, coatings, access and the end result. A condition assessment is the starting point.
Will laser cleaning repair structural corrosion?+
No. Laser cleaning prepares appropriate surfaces; perforated or weakened structural metal must be properly repaired or replaced.
Do you apply protective finishes after rust removal?+
Compatible primers, topcoats, cavity waxes and underbody coatings may be recommended where appropriate. The final system depends on the specific project.
