I am unable to use regular CA, so I use odorless where necessary, but am not excited about $10/oz. glue. On tight fitting joints I have loaded a syringe(no needle) with yellow carpenter's glue and then forced small amounts into the corners/crevices/wherever. The glue is forced into the tightest spaces. I have also used polyurethane glue and squeezed it into corners beside ribs. It expands as it cures and the fillets seem to offer additonal strength. This is based on my very limited building.
