5. Using the applicator included in the
replacement kit, apply glass primer (black)
around the upper and side perimeter of the
windshield edge and 7 mm inboard to the
inner surface as illustrated in Fig. 1A6-14. On
the lower edge, repeat the operation at a
distance of 35 mm from the edge of the glass
in a band 12 mm wide.
6. Check for voids or looseness in original
urethane. Cut away any loose pieces of
urethane and, using a suitable spatula, paddle
fresh urethane or silicon smoothly into any
voids.
7. Using a hand or automatic applicator, apply a
smooth continuous bead of urethane
adhesive, such as Betaseal 554.02 or
equivalent, between the centre and outer
edge, on top of original urethane and around
entire perimeter of the body opening. The
urethane bead should be a minimum of
10 mm in diameter.
Figure 1A6-14
NOTE:
Urethane service kits are available from most
windshield agents. Manufacturer's instructions
should always be followed.
IMPORTANT:
On the lower section of the body opening, care
must be taken to ensure the urethane bead
diameter is such that when compressed by the
windshield installation, the vehicle identification
number is not obscured.
NOTE:
In cold weather, the placement of cartridges
adjacent to a source of warmth will assist the flow
of urethane when using a hand applicator.
8. With the aid of an assistant, install the
windshield, using the previously attached
masking tape on the roof and windshield to
ensure accurate installation. Use wedges
placed at the lower windshield edge to locate
glass vertically in windshield opening. Press
windshield firmly into position.
9. Check effectiveness of seating from inside of
the vehicle. Should any gaps in the sealing
exist, apply additional urethane on the outside
to fill these gaps. Using a flat bladed tool,
sm ooth the surface of the ur ethane around the
edge on the outside of the windshield to
ensure effective sealing.
10. Water test the windshield, using a moderate
spray of water.
NOTE:
Do not direct a heavy stream of water onto freshly
applied urethane. If a water leak is evident, apply
additional urethane to the leal area, using a flat
bladed tool to work urethane into source of leak.

IMPORTANT:
If silicon is used for spot sealing, allow a minimum
of one (1) hour to permit the silicon to skin and
adhere to the original urethane, prior to water
testing the repair.
