I´m trying to replicate a wing but i´m having hard times figuring how can i do the seams of the top and bottom part so i can have a good cosmetic finish.

This is how I made neck for my harp.     http://www.talkcomposites.com/8522/Harp?Keywords=harp

Having made my 2 part mould I made the 2 sides.



Trimmed them back to the top edge of the mould.





Put them back into the mould and bonded with PT326 adhesive. Which after rubbing down looked like this.



I then painted over with GC50.



Then sanded down an and polished to this.



I may have over trimmed the 2 sides so that the joint is too thick but it still looks OK.
There may be a better way but this worked for me.
