What I use:

Basic building I use wood glue. This includes wing ribs, stab, fin, most of the fuselage including the formers.
On difficult situations where I need a quick set I will use mostly thin CA but occassionally I will use medium. This includes formers, some ribs, and sheeting that needs to be set quickly (but then I go back and reglue the whole thing with wood glue).
I will not use anything but 30-minute epoxy on such areas such as firewall, landing gear blocks, attaching stab and fin to the fuselage, joining the wing halves together and fireproofing the fueltank area and firewall (thinned with denatured alcohol for the fuelproofing).
I use clear fingernail polish for sealing graphics and for help in sealing the covering in hard-to-hold areas such as trailing edges, wing saddle area, engine compartment and landing gear area.
