You are right about the Boeing is keeping it shut, but then so is Airbus. There is even a poll guessing game on Flight International on wich aircraft mfg that will be first out with a new singel aile plane. I am guessing, or perhaps hoping, boeing as the NG is did take a lot from the classic.

I did aquire the Robart hing sockets for exactly that purpose. However I have yet to decide if to use them or not? Yes they are fat but offers a great feature to a finished plane.

My hingeline looks much like yours but with straight Robart hinges (and not even close to your perfection) I used TLAREB-system (that looks about right eye ball) to make them.

How is the durability and finish of Solartex compared to Koverall? As I understan Koverall need dope before painting...?

To be more specific i am contemplating btw Ultracote (light weight, easy, and cheap) and to sheet the fwrd fuz to fiberglass it and then cloth covering the aft fuz. If I go ahead with the second and more dear and difficult alternative I will then also glass the wings. However I need qualifyied weight estimate (penalty weight figure) for this before daring to attemt such a stunt.
