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.

SEALING AND CORROSION PROTECTION Underbody Protection Repairs
When body repairs are carried out, always ensure that
full sealing and corrosion protection treatments are
restored. This applies both to the damaged area, and
also to areas where protection has been indirectly
impaired as a result of accident damage or repair
operations.
Prior to straightening out or panel beating, remove all
corrosion protection material in the damaged area.
This applies in particular to panels coated with wax,
PVC underbody sealer, sound deadening pads etc.
WARNING: DO NOT use oxy-acetylene gas
equipment to remove corrosion prevention
materials. Large amounts of fumes and
gases are liberated by these materials when they
burn.
Equipment for the removal of tough anti-corrosion
sealers offers varying degrees of speed and
effectiveness. The compressed air-operated scraper
(NOT an air chisel) offers a relatively quiet mechanical
method of removal using an extremely rapid
reciprocating action. During use, direct the operating
end of the tool along the work surface.
The most common method is by the use of a hot air
blower with integral scraper.
CAUTION: High temperatures can be
generated with this equipment which may
cause fumes. Always exercise care in its
use.
Another tool, and one of the most efficient methods, is
the rapid-cutting’hot knife’. This tool uses a wide
blade and is quick and versatile, able to be used
easily in profiled sections where access is otherwise
awkward.
Use the following procedure when repairing
underbody coatings:
1.Remove existing underbody coatings.2.After panel repair, clean the affected area with a
solvent wipe, and treat bare metal with an etch
phosphate material.
3.Re-prime the affected area.DO NOT under any
circumstances apply underbody sealer
directly to bare metal surfaces.
4.Replace all heat-fusible plugs which have been
disturbed. Use rubber grommets of equivalent
size if plugs are not available, but ensure that
they are embedded in sealer.
5.Mask off all mounting faces from which
mechanical components, hoses and pipe clips,
have been removed. Underbody sealer must be
appliedbeforesuch components are refitted.
6.Brush sealer into all exposed seams.
7.Spray the affected area with an approved
service underbody sealer.
8.Remove masking from component mating faces,
and touch-in where necessary. Allow adequate
drying time before applying underbody wax.
Underbody Wax
After refitting mechanical components, including
hoses, pipes and small fixtures, mask off the brake
discs and apply a coat of approved underbody wax.
NOTE: Where repairs include the
application of finish paint coats in the
areas requiring underbody wax, paint
operations must be carried out BEFORE wax
application.
Underbonnet Wax
Where repairs have involved replacement of engine
bay panels, treat the entire engine compartment
including all components, clips and small fixtures with
an approved underbonnet lacquer or wax.
Proprietary Anti-Corrosion Treatments
The application of proprietary anti-corrosion
treatments in addition to the factory-applied treatment
could invalidate the Corrosion Warranty and should be
discouraged. This does not apply to approved,
compatible, preservative waxes which may be applied
on top of existing coatings.
