LR3/Disco 3
Under floor areas and rocker outer 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 underbody sealer back to a suitable
break point. Ensure that a clean metal surface is exposed and that the edge of the existing adheres soundly to the panel.
Apply new underbody sealer between primer and surface paint operations. Apply seam sealer as necessary before
application of underbody sealer. Ensure that blanking plugs and grommets in the floor pan (except those used for wax
injection) are fitted before underbody sealer application. Refit any heat-fusible plugs which have been disturbed in repair
with the aid of a hot air blower, or replace with rubber grommets

Precautions during body repairs and handling
Take care when handling the vehicle in the workshop. Underbody sealers, seam sealers, underbody wax and body
panels may be damaged if the vehicle is carelessly lifted.
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.
Fitting approved accessories
When fitting accessories ensure that the vehicle corrosion protection is not affected, either by breaking the protective
coating or by introducing a moisture trap.
Do not screw self-tapping screws directly into body panels. Fit suitable plastic inserts to the panel beforehand. Always
ensure that the edges of holes drilled into panels, chassis members and other body parts are protected with a suitable
zinc rich or acid etch primer, and follow with a protective wax coating brushed onto the surrounding area.
CAUTION : Ensure that suspension units, wheels, tires, power unit, drive shafts, exhaust and brakes
(including all mounting points) are shielded prior to application of fresh underbody sealer.
