Tailgate Glass; Spillage Of Material; Shelf Life; To Replace Tailgate Glass - Lotus Evora Service Notes

Lotus Service Notes
13. Insert three 6mm spacer blocks A132u0346F into the inside edge of each 'A' pillar bead.
14. Apply suction handles to the glass, and with assistance, carefully fit the glass onto the frame, taking care
to position it centrally (compare dimensions at each side between glass and body edges) and with the
upper filler strip in uniform contact with the roof edge. Press down on the glass around the periphery to
compress the joint onto the spacer blocks and then secure in position using duct tape or other methods
to support the screen until the adhesive has cured. This will take around 4 hours, with a longer period
required in dry atmospheric conditions.
15. Before curing, examine the whole length of the joint for integrity, and if necessary, extrude additional ad-
hesive locally into the joint to ensure complete sealing. use a spatula or similar tool if required to force
the adhesive into the appropriate area. use a spatula or whetted gloved finger to smooth out or remove
any excess extrunded material to leave a neat appearance. Alternatively, cut away after curing using a
scalpel knife.
16. Check the fitted condition of the lower rubber finisher, and if necessary, adjust the height of the windscreen
bottom gutter to align correctly with the screen bottom edge.
17. After adhesive cure, continue re-assembly in reverse order to disassembly, applying fresh double sided
tape to the 'A' pillar finishers.

Spillage of material

a) Any spillage of Betaseal onto unprimed glass can be readily peeled off after it has cured.
b) Any spillage onto the bldy can be removed with either Wipe Cleaner No.4, or white spirit.

Shelf life

a) Betaseal primer has a useful life of about 24 hrs. after exposure to the air, after which it starts to become
spongy. If the material is spongy, DO NOT uSE. Always use glass primer immediately on opening, and
replace the lid after use.
b) Betaseal has a shelf life of over 6 months at ambient temperature in the original unopened package.
BV.14 - TAILGATE GLASS
The grey tinted, 5mm thick, tempered glass screen, incorporates an electrical heating element and is bonded
to the composite tailgate panel using Betaseal flexible polyurethane adhesive. A black ceramic obscuration
band with graduated fade out, is applied to the inner surface periphery.

To Replace Tailgate Glass

Parts required:
-

Tailgate Glass.

- Screen adhesive cutting equipment.
- Betaseal Kit A075B6158F.
1. Apply suction handles to the outside surface of the glass, and disconnect the two HRS cables from the
inside.
2. using a dedicated vibrating cutting knife of suitable form, cut the adhesive bead around the entire periphery
of the screen, taking precautions as necessary to prevent damage to paintwork or body flange.
3. After cutting out the glass, remove old adhesive from the tailgate aperture sufficiently to leave a consistent
and flat surface for the new bonding medium.
4. 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).
5. Prime the bonding area on the glass to a width of 25mm with the primer in the kit, or with Betaprime 5500
