necessary before application of underbody sealer.
The following information details the materials that are
applied during manufacture for corrosion protection.

Td5 models.
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.
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.
Engine Bay Wax
Reinstate protective engine bay wax disturbed during
repairs using the approved material.
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.
Wheel Arch Wax
Reinstate protective wheel arch wax disturbed during
repairs using the approved material.
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.
