One of the best is "West System" brand for glassing your plane. Many hardware and building supply storex carry it. Or If you go mail order,
www.cstsales.com is the place.
And your LHS will probably have good resins for this as well.
Thin CA will work to attach the glass, but it's expensive to go that way.
A lot of people like to use water based polyurethanes. I haven't tried it.
