Did you use the Hysol 9430 for any particular attributes or was it just what you had handy? I have some West System epoxy that I've used for some of the fairing work...any reason it would not be equally suitable for bonding the fairing to the aluminum?

I had it handy; it's a good general use structural adhesive.

Compared to laminating formulations, epoxies intended as structural adhesive often spec lower in modulus, tensile, shear, and Shore hardness. Although "lower" as a desirable trait is non-intuitive, it is a trade-off in return for higher peel strength, the classic Achilles heel. Think "less brittle, more rubbery".
