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 t r i m from paint
contamination.
Figure 1.
Damage Recognition
Before any remedial action is carried out the

holed or torn it must be replaced. Repair should be
attempted only if the damage falls into one of the
following three categories.
