PRECAUTIONS

Creams are available to protect the skin from a con-

dition known as occupational, or contact dermatitis. This

common type of dermatitis is not contagious. Improved

resin formulas in the approved kits have almost elimi-

nated skin irritation. Cream is supplied with the kit for

men who may have a tendency toward skin irritation

from the resins or dust.

The application of these creams is recommended

whenever the Resin Kit materials are used. Generally,

the cream is not required when the plastic solder kit is

being used. Directions for using the cream is as follows:

a. Wash hands clean. Dry thoroughly.

b.
Squeeze about 1/2 inch (or 1/2 teaspoonful) of

#71 cream into palm of hand.

c. Spread evenly and lightly until cream disappears.

Work cream into cuticle, between fingers and

around wrists.

d. Apply second coat, repeating Steps b and c.

e. Hold hands briefly under cold running water to

set cream.

2.
Remove resin mixture from hands as soon as possi-

ble and imperatively before mixture starts to gel.

This can be observed by the action of the material

being used. Resin may be removed with lacquer

thinner by washing in soap and water.

3.
Respirators are recommended when grinding. Also

some minor skin irritation from glass and powdered

cured resin may be evident. Washing in cold water

will help to minimize.

4.
Use a belt sander with a vacuum attachment for dust

control if possible.
5. Resin mixtures may produce toxic fumes and should

be used in well ventilated areas.

6. Be careful not to get any resin material on clothing.

7. Use the right materials for the job. It is important

to use the approved kits because Chevrolet's rigid

quality standards assure you the right material to

do the job. Other materials available may not meet

the required engineering and safety standards.

8. Keep the materials, utensils and work area clean

and dry. These repairs involve chemical reactions,

and dirt or moisture may upset the chemical bal-

ances and produce unsatisfactory results.

9. Before starting repair operations, look for hidden

damage by applying pressure around the damaged

area, looking for hairline cracks and other breakage.

Check for minor damage at other points in the vehi-

cle such as around exhaust pipes, grille, headlamps

and points of wear or rub. Early repair of this

minor damage may prevent major repair later.

PLASTIC SOLDER
KIT

The Plastic Solder Repair Kit is used for minor re-

pairs on the Corvette body. These materials will produce

an easy, quick and lasting repair in the case of small

cracks, surface imperfections and small holes.

1.
Use paint remover or power sander, and remove

finish from damaged area. Carefully inspect for

other areas requiring repair.

2.
Mix the materials (fig. 72).

3.
Apply the material, using a putty knife or rubber

squeegee, Figure 73. Work the material into the

repair and build the material up to the desired

8. Impregnate backup plies of woven glass cloth with

prepared plastic mixture by dipping or brushing.

Remove excess plastic from cloth by squeezing.

9. Place impregnated backup plies on underside of

panels. If necessary, hold backup plies in place with

paper until plastic "gels."

10.
Prepare another plastic mixture of resin and

hardener and mix thoroughly. To this mixture add

Fig.

cut glass fiber (1/2" lengths) until mixture has a

putty-like consistency, or utilize glass cloth.

11.
Fill "V" groove with reinforced plastic material

or saturated glass cloth. Build up surrounding area

with sufficient material to allow for finish

operations.

12.
Allow patch to harden.

1.3. File or sand (#80-D sandpaper) to general panel

contour.

14.
Allow plastic fill to harden, then sand, preparatory

to paint operations.

HARD TOP

CARE AND STORAGE

The outside painted finish of the hard top should be

cleaned the same way as the rest of the car. The inside

headlining should be cleaned as outlined under Cleaning

Soft Trim.

When not using hard top, store it indoors where it can

be kept clean and dry. If the top is to be stored for a long

period of time, keep it covered to avoid dirt settling on

top and headlining. It is not advisable, however, to wrap

top assembly in a manner which will stop air circulation.

The hard top rear window is plexiglas and should be

cared for in exactly the same manner as outlined for the

convertible top rear window (see Care of Folding Top

in this section). Never scrape ice from rear window-

scratches are sure to result.

REAR WINDOW

Consult Figures 83 and 84 for parts identification.

Removal

1.
Remove hard top from vehicle. Place protective

covering over headlining.

2.
Remove screws retaining lower reveal moldings and

cap.

3.
Mark position of right hand upper reveal molding

end on top (fig. 85) and pry molding out of weather-

strip.
Repeat on left hand molding.

4.
Remove rear garnish moldings as outlined farther

on in this section.

5. Working from inside of top, carefully work weather-

strip from frame flange and push weatherstrip-

window assembly toward rear of top until free of

window frame.

6. Remove weatherstrip from window and inspect care-

fully. If weatherstrip is damaged, it should be dis-

carded. If it is in usable condition, clean off all

foreign material.

Installation

1.
Clean window frame of all old sealer, dirt, etc.

Remove and discard upper reveal molding retainers.

2.
Install twelve new upper reveal molding retainers

using mark made when removing reveal moldings

as guide. The two middle retainers should be 2"

center to center, those remaining should be approxi-

mately 7" apart as shown in Figure 86.

3.
As an aid to engaging reveal moldings in retainers

later on, place a short length of feeler stock behind

each as shown in Figure 87.

4.
Install weatherstrip on window.
