5. After cutting out the glass, remove old adhesive from body flange sufficiently to leave a consistent and
flat surface for the new bonding medium.
6. Clean the whole of the bonding surface on the new glass, and the bonding surface on the tailgate aperture,
with the wipe cleaner supplied in the Betaseal Kit (or Betaclean 3900 A100B6008V).
7. Peel off the backing tape, and apply a new finisher strip to the inside top edge of the glass, aligning the
cut back feature on the extrusion with the front edge of the glass.
8. Prime the bonding area on the glass to a width of 25mm with the primer in the kit, or with Betaprime 5500
(green cap) A120B6041V.
9. Prime and re-activate the prepared surface of the old adhesive on the body with Betawipe 4000
(A082B6355V). If the body side panel is new or without adhesive, prime the flange with Betaprime 5404
(red cap) A082B6337V.
10. 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.
11. Cut the nozzle of the Betaseal cartridge as shown in sub-section BV.13, and holding the cartridge vertically,
extrude a bead of adhesive around the glass periphery. Manipulate the two ends of the bead together to
form an unbroken ring.
12. As shown in the illustration, insert into the top run of adhesive two 5mm spacer blocks A124U0069F, and
into the bottom run, two 4mm spacers A075U0588F.
13. Using a suction cup, carefully position the glass onto its aperture, with the finisher strip consistently abut-
ing the roof panel, and the front edge aligned with the door shut rebate.
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 alterna-
tively, allow the adhesive fully to cure and cut away any excess using a scalpel blade. 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.
14. Refit front edge finisher, interior trim panels and rear clamshell.
Refer to sub-section BV.13 for spillage of material and shelf life advice.
