Built for the conditions we drive in
Coastal air, wet roads, winter grit and rural driving make underbody condition worth paying attention to. Our service is designed for owners who want to protect a suitable vehicle before corrosion becomes a bigger problem.
Our fixed treatment prices apply to eligible addresses on confirmed service routes, without additional travel charges. We may not be able to accept addresses outside our covered routes.
North Wales coast
Abergele, Rhyl, Prestatyn, Colwyn Bay, Llandudno and surrounding routes.
Inland routes
Conwy, Denbigh, Ruthin and other suitable North Wales locations by arrangement.
North Wales vehicle care
Coastal roads. Country miles. Everyday use.
Drivers along the North Wales coast and through inland communities encounter wet roads, salt and winter grit. We assess whether preventative underbody protection is suitable before agreeing a treatment. From Abergele, appointments can be arranged across the area where route, access and conditions allow.
