CA (Cyanoacrylate) glue, super glue, instant glue, ... may just be the greatest thing that comes in small bottles.
Especially for model airplane kits where everything "interlocks", you can puzzle the pieces together, add a drop of CA to each joint, and you're done.
On the other hand, there also disadvantages, the top 5 being:
- The bottle always clogs up
- The fumes sting my eyes
- I've glued myself to the plane too often
- I'm in no hurry to finish an airplane because I already have too many airplanes
- It doesn't "sand" well
