Any time I have two pieces of wood with a good fit, I hold them together and apply thin CA. If I can't reach the glue joint with the bottle, I use thick CA on the piece and then apply the piece of wood to the other piece to be glued.
Don't soak the wood with CA, it only needs a tiny bit to propagate.

For sheeting, I measure very carefully the sheeting needed, then assemble as many sheets as needed (but joint) then I sand it both sides and then cut it to fit properly. I do a dry fit, and mark all the longerons, ribs, whatever it will be attached to.

With the small drill bit, I punch holes every 1/2 inch on the marked sheet. I then refit the sheet to the structure, making sure to aline it perfectly. Then I put a drop of thin CA in every hole I made. I call this CA rivets.
