WOODGRAIN OVERLAY
SERVICE INFORMATION
Exterior woodgrain overlay is a weather-resistant
vinyl. The adhesive backing is protected by a paper
liner until removed for installation.
OVERLAY REPAIR
Small nicks and scratches on an overlay can be
touched-up with paint.
To eliminate blisters and air bubbles, pierce them
with a needle or pin. Force the trapped air out of the
hole and press firmly on the overlay. Heat also can
be applied to remove small wrinkles.
Whenever an overlay must be stretched, do
not slit or cut it. Instead, apply heat and press
or squeegee the overlay into place.
INSTALLATION REQUIREMENTS
Overlay replacement requires metal repair and
paint refinish to be completed before the overlay is
installed.
The work area temperature should be between
18ÉC (65ÉF) and 32ÉC (90ÉF).A woodgrain overlay
should not be replaced if the work area temper-
ature is less than 18ÉC (65ÉF).
The following equipment and material are neces-
sary for overlay installation:
²a commercial woodgrain overlay removal solution;
²a commercial adhesive removal solution;
²liquid dish detergent (for wetting solution);
²a mixture of wetting solution;
²a commercial wax and silicone removal solution;
²isopropyl alcohol (rubbing alcohol);
²a squeegee (4 to 5 inches wide, plastic or hard rub-
ber);
²a water bucket and sponge;
²sandpaper (no. 360 or no. 400, wet or dry type);
²a heat gun (or infra-red heat bulb);
²clean wiping rags or paper towels;
²a pair of scissors;
²a needle or pin; and
²a wax pencil.
Using a wetting solution helps the installation of
an overlay. Prepare a solution by mixing two or three
teaspoons of dish detergent with 1 gallon of water.
Do not use soap.
Too much detergent will reduce the effective-
ness of the mixture.

WINDSHIELD SERVICE INFORMATION
URETHANE ADHESIVE BONDING
The windshield glass is bonded to the body pinch-
weld flanges with urethane adhesive (Fig. 8). Thismethod of windshield installation complies with the
applicable Federal Motor Vehicle Safety Standards
(FMVSS).
WARNING: DO NOT OPERATE THE VEHICLE FOR
AT LEAST 24 HOURS AFTER WINDSHIELD INSTAL-
LATION. THE URETHANE ADHESIVE MAY NOT
PERFORM PROPERLY IN THE EVENT OF A COLLI-
SION IF IT IS NOT SUFFICIENTLY CURED. REFER
TO THE MANUFACTURER OF THE URETHANE BE-
ING USED FOR CURING TIME SPECIFICATIONS.
WHEN INSTALLING THE WINDSHIELD, DO NOT
USE URETHANE ADHESIVE IF THE EXPIRATION
DATE ON THE PRODUCT HAS PASSED. SAFETY
AND QUALITY ON THE REPAIR WOULD BE QUES-
TIONABLE.
REMOVAL/INSTALLATION METHODS
Windshield glass removal is accomplished by the
use of a razor knife and an electric hot knife to cut
through the urethane adhesive. This removal method
applies in all instances.
Depending on the circumstances, either one of two
windshield glass installation methods can be used:
²the short method, and
²the extended method.
The short method is used when the windshield
glass is removed intact, and the body opening and
the pinchweld flanges do not require repair.
The extended method must be used when the body
opening or a flange is damaged. The extended
method must also be used when urethane no longer
adheres to either the windshield glass or the pinch-
weld flanges.
