6. Prime and re-activate the prepared surface of the old adhesive on the tailgate with Betawipe 4000
(A082B6355V). If the tailgate bonding surface is new or without adhesive, prime the tailgate with Betaprime
5404 (red cap) A082B6337V.
7. Allow a minimum of 5 minutes for the primer to dry. If the glass is not fitted within 48 hours, the primer
should be re-applied.
8. Cut the nozzle of the Betaseal cartridge as shown in sub-section BV.13, and holding the cartridge verti-
cally, extrude a bead of adhesive around the glass periphery using a finger against the glass edge as a
guide. Manipulate the two ends of the bead together for a consistent joint.
9. Cut six 4mm spacer blocks from the material supplied in the Betaseal kit (or use 6 off A124u0069F), and
position in the inside edge of the adhesive bead, two along the top bead, two along the bottom, and one
centrally in each side bead. These spacers are used to control the fitted height of the glass.
10. using suction handles, carefully lower the glass onto the tailgate, and position centrally in its aperture.
Press around the periphery of the glass to compress the adhesive until contact with the spacer blocks is
felt. Carefully examine the integrity of the whole length of the joint, if necessary using a spatula to force
extra adhesive into any depleted areas. Wipe off any excess adhesive extruded from the joint, or alter-
natively, allow the adhesive fully to cure and cut away any excess using a scalpel blade.
11. Position the tailgate horizontally and use duct tape to hold the glass in position until the Betaseal is fully
cured. This will take approximately 4 hours dependent on atmospheric conditions, with a longer period
required in dry atmospheres. Reconnect the HRS cables.
Refer to sub-section BV.13 for spillage of material and shelf life advice.
BV.15 - CABIN REAR WINDOW
The cabin rear window is a double glazed unit to enhance insulation from engine bay heat and noise, and
consists of two clear, 4mm thick, tempered glass panes, bonded around the periphery to a 6mm thick synthetic
spacer, with the sealed space filled with argon gas. A black ceramic obscuration band with graduated fade
out, is applied to the forward face of each glass pane. The window is bonded to the cabin rear bulkhead using
Betaseal flexible polyurethane adhesive.
BV.16 - REAR QuARTER LIGHT WINDOW
Each rear quarter light window comprises a green tinted, 4mm thick, tempered glass pane, bonded to the
body side panel with Betaseal flexible polyurethane adhesive. A black ceramic obscuration band with gradu-
ated fade out, is applied to the inside periphery of the glass, and an extruded rubber finisher is bonded along
the top edge. It is unlikely that the top finisher will be re-usable after glass removal.

To Replace Rear Quarter Light Glass

1. Remove the rear clamshell (see sub-section BV.6).
2. Pull off the top rear section of the door weatherstrip seal, and peel off the rubber finisher moulding from
the front edge of the quarter light glass.
3. Remove the rear quarter trim panel and 'B' post upper trim (see section VE.11).
4. From inside the car, and using a dedicated vibrating cutting knife of suitable form, cut the adhesive bead
around the periphery of the window, taking care to avoid damage to paintwork or body flange.
