What we check before treatment
The right product depends on the underside condition. Preparation matters more than just asking for a brand name coating.
Vehicle use
Vehicles used on wet hills, rural roads and salted winter routes need careful preparation before underseal and wax protection.
Treatment choice
Underseal, cavity wax, rust converter, stone chip, Dinitrol, Waxoyl, Schutz, Raptor or lanolin-based products are chosen by condition and use.
Aftercare
Annual inspections check damaged coatings, top up cavity wax and keep warranty paperwork current.
Frequently asked questions
Do you rust proof 4x4s from Caerphilly?
Yes. 4x4s are checked around chassis sections, crossmembers, arches, suspension mounts and cavities before coating.
Can road salt from hill roads cause underside corrosion?
Yes. Salt, grit and damp debris can sit around seams and brackets, especially if the vehicle is used through winter.
Do I need repairs before underseal?
Sometimes. If preparation exposes holes, heavy pitting or weak metal, repairs need to be discussed before any protective coating makes sense.
