Hmm, true. Might be worth asking - although I expect the tolerances are a lot
tighter for laminated glass, so consequently the depth of 'glue' which needs
to be seen through is a lot thinner (on the HP250 CRT the old sealant was
close to 5mm thick toward the edges of the CRT face)
I am curious as to what the glass firms use, though, as it seems more robust.
Having owned a few 70s vehicles I've seen the effects of windscreens starting
to delaminate at the edges - but it goes a milky colour and always starts from
the very edge, whereas CRT 'sealant' tends to go more like mould, and often
seems to start from random points (although it tends to be worse at the edges)

Air bubbles in the sealant are going to be the
main problem; I expect
that it'll need something that's a lot more liquid before setting
which can be poured down between the CRT and faceplate, after sealing
the faceplate around the edges with more conventional stuff (as I did)
to contain it until it's dried.
You probably want to talk to a windscreen specialist. They make funny
bits of curved laminated glass all the time.
