Temporary plan = get the original back on (I want the roof closed) so this is the plan.

Wire brushed (aggressively) and treated with Bilt & Hamper Hydrate-80.








I also thinned it and loaded the Hydrate-80 (20% water, it is water based anyway) into the inner edge so it penetrated by capillary action under the tray/glass covering areas that I could not reach with a brush, after an hour I used light air pressure and tilting the glass onto its edges to force it into any areas that might not have received coverage due to air-traps.

Left to dry overnight them I attacked it aggressively again with a wire bush and re-coated with Hydrate-80. Whilst this was drying all rust flakes were removed from the seal (surprised how much was in there) and this was blown out/brush clear.

Black Primer and two top coats of Satin-Black.



The next step is to prepare/clean/oil the cassette, then apply PU Adhesive to the seal and whilst that is still soft attach the glass/frame to the runners and close the roof slowly to the closed position. I hope excess PU Adhesive will "fill the voids" left after the rust was removed.
Once set I will use a fine tube nozzle to seal the top seal edge and "in-fill" the inner edge to prevent moisture ingress.

Cassettes. Xm ones very different.. The part the glass slides into is a full.. Urrmmm.. Enclosure.. They are damm heavy to take out too..

Xantia ones.. Bearing in mind there's what 3 years between the designs in xantias favour.. The xantia glass slides back into an open space.. And therefore is a lot lighter.. Smaller.. And different but are still webasto units.

Well that is back in and tight, will leave it overnight to let the adhesive set.

Looks tidy enough.

The sunroof works and the seal has stayed on....as a temporary result and as they say ooop narth..........that'll do fa naw

. . . held on bah gum

Total PIG of a sweaty job.....stuck together with a sealant who's strength is only known by those flying starships in the distant future !

Am I right in thinking that's an S2 front indicator / fog lamp unit..?

Why the dismantle..?

Non fog-lamp type.....need to convert it into one using the crappy one from the car that is dull/grey/dirty and dusty from a long time with a broken glass.

Glass removal is a massive PITA, heat and levers coupled with a worrying amount of force.

In the "spot lamp free" unit the reflector mounts are already there.


The hole needs a threaded insert pressed/glued in so I scavenged the threaded insert and the adjuster screw.


I need to drill a hole for the adjuster screw in the bottom but thankfully the square socket is also moulded in as with the twin lamp unit.
