I just started a Sig Somthin Extra Kit. The instructions say to use medium or thick ca for the entire thing. Previous posts here in the kit forum stressed following instructions exactly so thats what Im doing. I've started both wings. It seems as if its going to be plenty strong. I goofed and glued two ribs on the the wrong order and I played h*ll geeting them loose. So is this ok? Is it normal to only use CA when kit building? This is my first kit....
