I use liquid and somewhat slow drying glues for almost everything I build using FB.
As things can take time to dry/set and I often build more than one plane at a time I stumbled upon a way to glue and hold those fold-up fuselages without clamps, weights, extra hands, or any real restraining device and it works without damaging the FB at all.
I minwax/seal the fuselage outer surfaces prior to folding. When dry I apply the glue and use cheap clear packing tape across the glued edges to hold the paper flap down and the pieces in perfect alignment until dry/set. I only wipe the tape with a finger so that I remove the air bubbles, DO NOT APPLY MUCH PRESSURE!
I normally use lengths of around 70 to 100mm of the tape with the ends turned over on themselves so I have non-sticky flaps to grab easily when the glue is dry and the tape is to be removed!
Here is a very poor pic of the tape being used to hold a fuselage together whilst the glue dried. (From my Slick Trick build thread).
It works for me!
have fun!
