I just finished covering SE #2 and did it separately. I did a bit of thinking first and don't feel that I have compromised strength in any way.
First covered the fuse leaving the stab mount uncovered. I had already shaped the filler blocks as per instructions. Then placed the stab and marked where to cover to and where to leave uncovered. After covering epoxied the stab in place.
Worked in a similar way with the fin, doing plenty of trying before glueing. Covered the filler blocks before fitting and left an overlap at the front which I ironed down over the back of the fuse.
With all the ironwork in place I don't expect to lose the tail! Will let you know
