Simon,
Have a look at the LS 8 versions that are around (mine is a 2001
LS8-18). No mylar seals on the wings, only on the rudder and elevator
(those are not recessed). There are two internal seals on the
ailerons that keep top and bottom surfaces separated. Seems to work
well from the performance I am seeing. I would first worry about the
internal seals and then go fly a lot before spending money on Mylar!

I tried asking this questionon on a different thread; it may have been too
off topic, but I didn't get much of a response:

I'm putting mylar control surface seals on the wings of a Mini Nimbus this
winter. At the moment I'm planning on fixing them to the finished wing
surface. The alternative is to rebate (recess) them into the wing. This
creates a smoother surface but costs more money and is harder to undo.

Anyone know of any research (or anecdotes) on the impact on wing performance
of leaving such seals proud of the surface? My assumption is the airflow
over the wing is pretty much turbulent at the wing/aileron join anyway, so
the impact should be minimal.

If the recommendation is to rebate, is it equally critical for the both the
upper and lower surfaces?
