Graham & David thanks
Fortunately I wont even come close to the leading edge and the difference
is very small...so I am thinking of sanding forward of the join maybe 2"
and taking off the gel coat rear of the join.
By the way has anyone inspected the bonding? I was thinking of using one
of those endoscope/inspection cameras through a 10mm hole in the rear skin
(forward of the flap) . Peace of mind I suppose. The close out forward of
the flap is a very light weight affair and can not be that critical to the
wing strength.
Happy New Year to all
