REAR WHEEL COVER (CAPRICE, AND OPTIONAL
ON OTHER CHEVROLET MODELS EXCEPT
STATION WAGONS)
Removal and Installation
Lift the skirt (fig. 15) retaining lever (at the bottom
inside skirt flange) over the lip of the flange and pull it
downward. Pull the skirt downward and out of the open-
*
ing. To install the skirt: position it inside the opening,
insert the rod into the slot, lift the skirt and attach the
hook to the wheel opening flange. Hold the skirt from
below and behind to assure proper hook attachment then
lift the retaining lever up and into the skirt lip. Check

SIMULATED WOOD GRAIN MOULDING
(STATION WAGONS ONLY)
The wood grain transfer film is a vinyl material with
a pressure sensitive adhesive backing. The transfers
are serviced in pre-cut panels. The shelf life of this
material is 90 days at a maximum temperature of
105°
F.
Removal
Remove the mouldings from the affected panel. Re-
move the transfer film by lifting an edge and peeling the
material from the painted surface. Exercise care so as
not to damage the paint.
NOTE: Application of heat to the transfer and
panel with a heat gun or heat lamp will aid in the
removal.
Installation
Preparation of the surface to which the transfer will
be applied is very important. In cases where body metal
repair has been made it is necessary to prime and color
coat these areas to blend with the undamaged surface.
Apply the transfer film to color coated panels only, never
to bare metal or primer. The surface must be free of
any imperfections that may high-light through the film.
Remove dirt nibs and other foreign material in the paint
by light sanding with 600 grit sandpaper.

The temperature of the body must be maintained at a
moderate level between approximately 65 and 90 degrees.
Too warm a body will cause the wood grain film to stick
prematurely while too cool a body will reduce the adhe-
sion of the wood grain film. Cool, the body panel with
cool water when too warm and heat the body panel with
a heat gun or a heat lamp when too cold. Just prior to
application of the transfer film clean the painted surface
with a non-petroleum base volatile cleaner and allow to
dry.
Follow the steps below for easy application of the film.
1.
Cut the tape backing the entire width of the transfer
at the approximate centerline of the film exercising
care not to damage the transfer film.
2.
Peel the paper backing from one half of the film.
3.
Align the upper edge of the half of the film with the
paper backing to the lower edge of the pierced mold-
ing holes making sure that the transfer is centered
on the panel.
4.
Starting at the center of the transfer and using a
water dampened rag, press that half of the transfer
with the backing removed on to the panel. Work
outboard from the middle to the edges. Remove all
air bubbles.

NOTE:
The transfer can be pulled back from
the panel and reinstalled if large air pockets
develop. Exercise care not to stretch the ma-
terial. Small air bubbles may be removed by
piercing the film at the bubble with a pin and
pressing the bubble down.
5. Remove the backing from the other half of the trans-
fer. Apply this half in the same manner working
from the center to the end and from the middle to
the upper and lower edges.
6. Fold the transfer over the door or quarter edges and
press to the hemming flanges. Application of heat
with a heat lamp or heat gun will aid in folding the
transfer over the edge.
NOTE:
If the transfer film will not adhere to
the flange, brush a clear vinyl adhesive to the
back edge of the film and reapply.
7. Install the moldings.
