Once the
putty is dry we can sand it down (first with the nail file and then
with wet sandpaper). When doing this we need to be careful, as the
details that stick out from the fuselage are very small and if we
sand these down with force, we can easily eliminate them and cause
irreversible damage.
In the
next photo you can see how we have framed the joint of the two parts
of the wing and how we have added the putty (here you can see it dried
off).
