Putty location - vehicle exterior
The previous illustrations show the areas where putty is applied. Putty is applied to areas to act as a gap filler and for
sealing seams. When applying putty ensure that correct area is filled and where necessary, is smoothed to give a
cosmetically acceptable condition.

Structural adhesive
Adhesive on rear wheel arch outer assembly.
Joints symmetrically opposite to those shown are also treated. Apply 3 mm diameter beads to all joints shown.
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 to bond two metal surfaces and also to seal the joint against
ingress of dust, moisture and fumes. This material is not suitable for service use and, during repair, should be
substituted by an approved Structural Adhesive.
BODY SEALING MATERIALS, MATERIALS AND APPLICATIONS, Approved materials.
Those joints which require the application of structural adhesive are detailed in the following figures. Only joints
applicable to service panels are included. Apply structural adhesive where indicated or to the mating panel surface.
CAUTION: When separating a joint treated with metal-to-metal adhesive, it is important to avoid distortion.
Heat the joint gradually until the bond weakens sufficiently to permit panel separation.
NOTE: When spot welding through metal-to-metal adhesive, take particular care to adjust the transformer setting to
ensure a reliable weld.

1 10 mm (0.393 in) x 2 mm (0.078 in) 'Butyl strip'
2 10 mm (0.393 in) x 1 mm (0.039 in)'Butyl strip'
3 Interweld sealant
Butyl tape is also applied to the bodyside rear glass aperture flanges. On the forward edge of the aperture a 15 mm
(0.590 in) x 2 mm (0.078 in) strip is applied, and on the lower and rearward edges a 10 mm (0.393 in) x 2 mm (0.078
in) strip is applied.
During production, interweld sealer is applied to critical joint areas. The material used is a heat cured, rubber based
sealant which serves to seal two metal surfaces and prevent the ingress of moisture, dust and fumes. Before refitting
a replacement panel, apply interweld sealer to areas indicated or to the mating panel face.
