Body Repair - RTM Body Panels
RTM Body Parts
Certain exterior panels of the vehicle are
manufactured from RTM as shown as shaded areas
in Figure 1. The Front and rear bumpers are made
from
R-RIM
Repair Procedures
Cosmetic Damage
Repair the paintwork using standard procedures.
Substrate surface
Where the defect does not affect the physical
strength of the panel, fill and repaint using standard
techniques.
Substrate Penetration
No reliable repair procedures are possible to correct
major physical damage to RTM panels. Any small
defect which do not affect the intgrity or security of
the panel may be filled and repainted at the owners
risk.
Uote: Becauseof the inherent flexibility of plastic panels,
hard filler may
crack.
Such repairs cannot
therefore
be
guaranteed.
Where the damage affects the security and or the
integrity of the panel, it must be replaced.
Precautions during Paint Operations
When any repair operation is being completed on
the DB7 paintwork, take particular care to protect
the leather upholstery and trim from paint
contamination.
Figure 1.
Damage Recognition
Before any remedial action is carried out the
damaged should be
assessed.
If the cover has been
holed or torn it must be replaced. Repair should be
attempted only if the damage falls into one of the
following three categories.
Cosmetic
Substrate surface
Substrate
penetration
Abrasion to the surface paint
finish
Deep scratches, gouges or
localised radial stress cracks.
Splits not exceeding 100 mm.
Splits radiating from a gouge
and accompanied by localised
stress cracks.

Roof Seals - Adjustment
9.2.01.6 - Roof
Seals
- Adjustment
Seal adjustment is done in two stages. First stage -
lateral adjustment, and second stage - outward
adjustment. Seals are packed out using selected
packing strips.
Lateral Adjustment
Partially open the roof.
Front frame seal only: Remove the seal retaining
plate.
Remove the seal from the channel.
Slacken the channel securing screws and reposition
the channel as required, moving it on the slotted
screw holes (Fig 3-A). Tighten the channel securing
screws.
Apply soft soap to the seal and insert the outer seal
edge into the channel. Then press in the inner edge
to fully seat the
seal.
Refit the seal retaining plate.
Outward Adjustment
Partially open the roof.
Remove the seal retaining plate. Remove the seal
from the channel. Mark the position of the channel
for reference, release the screws and remove the
channel.
Select the appropriate packing (Figure 3-B)(see
DB7 Volante parts manual):
Rear frame seal foam strip
Front frame seal foam strip
Main column seal foam strip
Upper 'A' post seal foam strip
Note: The foam strips are for full length packing. For
packing at one end
only,
a shorter rubber
wedge
can be
used. (Fig 1-C)
Fit the foam strip/rubber wedge and channel. Align
the channel in the previously marked position. Fit
and tighten the securing screws.
Apply soft soap to the seal and insert the outer seal
edge into the channel. Then press in the inner edge
to fully seat the
seal.
Refit the seal retaining plate.
Note: It is imporrtant at all times to retain the overall
shapeoftheroofsealline(Fig4).
Wherea
leak necessitates
the
adjustment of only
one
or two
seals,
ensure
that
there
are
no
misalignments.
A more
satisfactory result
may be
obtained by adjusting the adjacent component, i.e. the
door
glass
or rear quarter glass.
The relationship between the roof seals is very
important. Two seals in very close contact will
promote leakage problems. Sealing will be far more
effective ifthe seals touch lightly or exhibit a small
air gap (Fig 4).
