I have been doing this a while now so getting the pieces lined up and glued together is not a problem.
I use a medium viscosity cya adhesive along the seam then press and hold - once it is together I paint the outside of the seam with Tamiya liquid cement..it essentially erases the seam.
Then a light sanding with fine sandpaper when its dry and you are ready for paint.
I had considered buying a full size 1/32 scale pilot (1/24 would not have fit into the cramped cockpit) but the least expensive one was going to be more money than I could justify spending and little pilot busts are easy to fit
in plus - you cant really tell its not a full figure unless you look in there
