John,
I did a similar thing on first GE using wooden tabs to hold her together at the seams while I faired. In the end, It was a wasted step. When I moved the tabs I still had a little work to do. In the end it was just better to seam the inside, run a ROS down the out side and then seam the out side. The inside seam glassing gives you a solid coninuous surface to work against verses the iteritives point strength of a doweled job with changing curves in between. Additionally, It has you fairing once rather then twice. The savings in time is a lot and the appearnace is the same. Ben der don dat Won't dood it agin
