I personally would go to a good plastics supplier and replace the glass with perspex, that way you can stick it and mechanically have the hinge bolted on.

If you want to stick with glass (excuse the pun) I d suggest the best bet is Silkaflex - comes in various types - most chandlers stock it.

Hi Robin

It may be worth trying a car windscreen specialist. Many windscreens seem to be "bonded in" these days.

Not supprised you are getting stoney silence from Bavaria; Your hinged window sounds like a pretty poor design to me. Is it possible to change the whole assembly for a properly made hatch?

Try Hafixs super glue, it's a Cyanoacrylate but resin based, allows movement prior to sticking and appears to stick anything to anything. ( but not to skin).I saw it demonstrated at the Southampton Boat show and was very impressed. The salesman stuck neoprene circular seals  together, one drop on the 5mm dia cut end and two of us, at 16 and 18 stone respectively, could not pull the joint apart, although the seal stretched to about 1 foot long. Polythene to polythene, again stretched to breaking point but did not break, galvanised steel to ditto, ceramic to ceramic. My pal and I both bought a 50cc bottle at about £10.00 and it is kept in the fridge. see www.hafixs.co.uk
