Thanks all for your replies. I will give it a bash when the new lens arrives.

When we built my friend's RV-8, we simply used West Systems 105 epoxy with the slow hardener to bond the fiberglass fairing all around the front windshield to the rollbar and fuselage. We scuffed up all the plexiglass contact surfaces and metal surfaces thoroughly with 80 grit first. Three years later, it's still bonded perfectly well, and no sign of any delamination of the bond or any cracks or crazing in the plexiglass.

Thanks Neal. Makes sense I guess, since Van's method of making the fairing is to lay up the fibreglass strips directly on the windshield after masking and scuffing so it gets bonded from the start. I made mine using a different layup technique that requires bonding after finishing. I have plenty of West 105.
Did you (or should I) add any flox to the mix to help fill any small gaps on the underside of the fairing?
