REPAIR PROCEDURES
For repair procedures refer to General Motors
Service Information Bulletin (B-4). Copies of the
fiberglass repair bulletin (B-4) may be ordered from
The aluminum panels on the body may be re-
paired if damaged. Filler putty can be used for minor
dents, scratches, scrapes etc. However, major dam
age to a panel will require removal of at least part of
the panel. Because the panels are secured to the ribs
with a polyurethane adhesive, separating and remov-
ing panels is difficult. Any rivets used on the panels
are easily removed by drilling off the rivet head and,
using a punch, drive out the rivet shaft.
All windows, access doors, vents, belt and roof
line trim mouldings in the damaged area should be
removed before removing the panel.
An air chisel will be helpful to remove the panel.
Operate the air chisel along the rib to break the
adhesive bond between the panel and the rib.
CAUTION: Be careful during chiseling, saw-
ing, drilling etc.
On
the aluminum panels not
to damage wiring, piping, insulation, com-
ponents etc. which are located immediately
behind the panels .
Any damaged rib will have to be straightened,
replaced or have shim material fastened to the rib so
proper support will be provided for the aluminum
panel.

SHEET METAL REPAIR
BODY 1- 2 5
Materials, for repairing damaged fiberglass pan-
els, are available in kit form through GM Dealer-
ships, or equivalent kits can be purchased locally.
A replacement panel should be fitted after the
ribs have been thoroughly cleaned of adhesive . A
suggested method would be to grind off the adhesive
with an extra coarse disc on an air driven grinding
wheel.
With the ribs cleaned a new panel may be fitted
into the opening. Next, with the panel in place drill
holes, or use existing holes, (at each corner and along
the belt line and roof line) through the panel and rib
for using pop-rivets.
Remove panel and apply adhesive such as manu-
factured by Minnesota Mining and Manufacturing,
3539 A/B, or equivalent to the rib. This is a two part
(base and accelerator) urethane adhesive designed
for bonding aluminum, polyester, and steel. It is es-
sential that the surface be thoroughly clean, dry, and
grease free before application. Follow the manufac-
turers' mixing and curing instructions . Avoid re-
peated skin contact and use only in a well ventilated
area .
Position panel in place and pop-rivet using pre-
drilled holes. The adhesive will cure at room temper-
ature in 24 hours. The rivet holes may be ground off
and the holes filled with a body putty.
2. This will allow access to the four retaining
