Salutti tutti again,
 
I'm not far off being ready to close a set of flaps, ailerons and for the wings I will use the slow (2 hour) EA9339 Hysol from Watkins and Associates www.watkins-associates.com  To properly electrically connect and protect the bond line between the top and bottom wing skins from the effects of lightning strikes I am thinking to make the Hysol conductive with the addition of silver powder/flake 99.99% pure which is specifically designed for inclusion in epoxy to make it conductive.
 
My thinking is that when the wing leading edge joggle is sanded back to carbon fibre and the silver is embedded inbetween the top and bottom skins in the joggle the carbon fibres of the top and bottom wing skins are connected, along the full length of the leading edge joggle.
 
Can anybody knowledgable person think of any good reason to not include this silver powder/flake in the hysol?
 
Ciao,
 
Robert d'Italia.
