Hi,
I'm currently building my first kit a 4* 40. I have finished the wings but now that I am trying to fit them together with the diehedral brace in it has become apparent that I put too much diehedral on the first wing ribs on each wing. (my card table is bowed). So when i put the wings together there is a 1/2 cm gap between the tops of the wing halves. I'm wondering how to fix this.

Should I just pour epoxy into the gap? I really don't want the amount of diehedral that i would have if I altered the diehedral brace to fit the two wings "snug."

Thanks
