It's good to see you guys are still working on your Gee Bee's.
Zpat,
I covered the wood part of the wing fillet with Solartex. I used epoxy and micro balloons to transition between the covered and front plastic wing fillets. I then primed and painted the front plastic wing fillet parts black as I painted the Solartex.
I used some silver elastic cord that I found at Hobby Lobby for the flying wires. They are just for looks.
