Any of the glues you use in regular styrene cast kits is okay. It is the same material, just processed in a different manner. If you use regular (thin) CA, you must make sure, however, that fit of parts is good, since the vac kits may not fit as well as cast ones without more cleanup.
I often use wood for some interior stiffening structure, and the wood to styrene bond should either be gel CA or epoxy.
