SEALING AND CORROSION PROTECTION
CORROSION PROTECTION
The following information details the materials that are
applied during manufacture for corrosion protection.
Factory Treatments
The Defender 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 and box
sections.
•
A final coating of underbody wax to cover
the complete underfloor including
components but excluding brake discs,
exhaust system and propeller shafts.
•
A coat of protective lacquer applied to the
whole body.
•
A coat of protective wax applied to the
engine bay and wheel arch areas.
NOTE: Do not apply wax to engine bay of
Td5 models.
In addition to the above measures, all steel parts are
zinc-coated both sides.
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.
Cavity Wax
Cavity wax is applied to certain box sctions 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 200 mm (7.9 in) beyond
the area where new underbody sealer is to be
applied.
Engine Bay Wax
Reinstate protective engine bay wax disturbed during
repairs using the approved material.
Wheel Arch Wax
Reinstate protective wheel arch wax disturbed during
repairs using the approved material.
