I use thin CA, Aliphatic resin (yellow Carpenters glue ) and 30 minute epoxy and go over the various glue joints.

30 min. epoxy around the landing gear mount(s ) and firewall area...wing center section...high stress areas.

I use a pipette to apply the thin CA wherever I can get it...typically where I can't get to with the Carpenters glue. (I also use a small modelers paint brush to work the yellow glue into the joints.
