I'm going to be repairing an old trainer, and I was wanting to use some TiteBond Wood Glue, to conserve my CA & Epoxy. Where should I Not use TiteBond?

Main damage is sides, bottom plate, and firewall.

And being I have 2 Trainers, 3 Mid Wings I was thinking of converting the wrecked trainer to a LowWing. The wing has 0 dihedral, it was taken out by the previous owner. It's a solid wing, But I am thinking also about cutting it apart and making it a two piece. (But May Not)It's about 63" long now. If I drop the wing would it's place need to be moved forward or backwards any or just drop itstraight tothe bottom?

Thanks
