SEALING AND CORROSION PROTECTION
CORROSION PROTECTION
Factory Treatments
The New Range Rover is treated with the following
anti-corrosion materials in production:
•
A PVC-based underbody sealer material
which is sprayed onto the underfloor, wheel
arches and undersill areas.
•
An application of cavity wax which is
sprayed into enclosed cavities, box
sections and lower inner door panels.
•
A final coating of underbody wax to cover
the complete underfloor including
components but excluding brake discs.
•
A coat of protective lacquer or wax applied
to the engine bay area.
In addition to the above measures, all steel parts are
zinc-coated both sides, and front wings, door and
tailgate skins are manufactured from aluminium.
The information given on the following pages is
intended as a guide and shows the areas to be
treated with cavity wax, as well as the access holes
used during manufacture. See GENERAL
INFORMATION DATA, Sealing and corrosion
protection section.
Underbody Wax
A coat of underbody wax is applied to the entire
underbody inboard of the sill vertical flanges, and
covers all moving and flexible components EXCEPT
for wheels and tyres, brakes and exhaust. The wax is
applied over paints and underbody sealers.
The underbody wax must be reinstated following all
repairs affecting floor panels.
CAUTION: Old underbody wax must be
completely removed from a zone
extending at least 200mm (7.9in.) beyond
the area where new underbody sealer is to be
applied.
Underbody Sealer
Underfloor areas and outer sill panels are treated with
a Plastisol PVC underbody sealer. This material is not
suitable for re-treatment.
When repairing areas of underbody sealer, strip the
factory-applied material back to a suitable break point,
ensuring that a clean metal surface is exposed and
that the edge of the existing material adheres soundly
to the panel.
Blanking plugs and grommets in the floor pan (except
those used for wax injection) MUST be fitted before
underbody sealer application. Heat-fusible plugs
which have been disturbed should either be refitted
with the aid of a hot air blower or replaced with rubber
grommets.
NOTE: Application of new underbody
sealer must be carried out between primer
and surfacer paint operations. Areas
where seam sealer is used should be re-treated as
necessary before application of underbody sealer.
CAUTION: Ensure that suspension units,
wheels, tyres, power unit, driveshafts,
exhaust and brakes (including all
mounting points) are shielded prior to application
of fresh underbody sealer.
Engine Bay Wax
Reinstate protective engine bay wax disturbed during
repairs using the approved material.
