SEALING AND CORROSION PROTECTION Stone Chip Resistant Paint/Primer
Re-treat all areas protected with factory-applied
anti-chip primer with suitable approved material in
repair.
Inspections during Maintenance Servicing
It is a requirement of the Land Rover Corrosion
Warranty that the vehicle body is checked for
corrosion by an authorised Land Rover dealer at least
once a year, to ensure that the factory-applied
protection remains effective.
Service Job Sheets include the following operations to
check bodywork for corrosion:
With the vehicle on a lift, carry out visual
check of underbody sealer for damage.
With the vehicle lowered, inspect exterior
paintwork for damage and body panels for
corrosion.
NOTE: Wash the vehicle and ensure that it
is free from deposits prior to inspection. It
is part of the owner’s responsibility to
ensure that the vehicle is kept free of
accumulations of mud which could accelerate the
onset of corrosion. The Dealer MUST wash the
vehicle prior to inspection of bodywork if the
customer has offered it in a dirty condition, and
pay special attention to areas where access is
difficult.
NOTE: The checks described above are
intended to be visual only. It is not
intended that the operator should remove
trim panels, finishers, rubbing strips or sound
deadening materials when checking the vehicle
for corrosion and paint damage.
With the vehicle on a lift, and using an inspection or
spot lamp, visually check for the following:
Corrosion damage and damaged
paintwork, condition of underbody sealer
on front and rear lower panels, sills and
wheel arches.
Damage to underbody sealer on main floor
and chassis members. Corrosion in areas
adjacent to suspension mountings and fuel
tank fixings.
NOTE: The presence of small blisters in
PVC underbody sealer is acceptable,
providing they do not expose bare metal.
Special attention must be paid to signs of damage
caused to panels or corrosion material by incorrect
jack positioning.
It is essential to follow the correct jacking and lifting
procedures.See GENERAL INFORMATION DATA,
Information section.
With the vehicle lowered, visually check for evidence
of damage and corrosion on all painted areas, in
particular the following:
Front edge of bonnet.
Visible flanges in engine compartment and
boot.
Lower body and door panels.
Where bodywork damage or evidence of corrosion is
found during inspection, rectify this as soon as is
practicable, both to minimise the extent of the damage
and to ensure the long term effectiveness of the
factory-applied corrosion protection treatment. Where
the cost of rectification work is the owner’s
responsibility, the Dealer must advise the owner and
endorse the relevant documentation accordingly.
Where corrosion has become evident and is
emanating from beneath a removable component
(e.g. trim panel, window glass, seat etc.), remove the
component as required to permit effective rectification.

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.

SEALING AND CORROSION PROTECTION SEALANTS AND ADHESIVES
Structural Adhesive
Metal-to-metal adhesive is applied to critical joint
areas during factory assembly. The material used is a
high-temperature, heat cured, nitrile phenolic which
serves both to bond two metal surfaces and also to
seal the joint against ingress of dust, water, petrol and
fumes. This material is not suited for service use, and
should be substituted in repair using a suitable
medium strength adhesive.
When separating a joint treated with metal-to-metaladhesive, to avoid distortion it is recommended that
the joint be gently heated until the bond weakens
sufficiently to permit panel separation.
NOTE: DO NOT carry out MIG welding on a
joint area which has been treated with
metal-to-metal adhesive until all traces of
adhesive have been removed.
The following Illustrations show the treatment areas
for Structural Adhesive.
All areas symmetrically opposite to those shown are
also treated.
