David,
I used Superfil from Poly Fiber Aircraft Coatings http://www.polyfiber.com/
step/
It is not far off half the weight and very easy to sand. It also bonds to i
tself well so that constant additions work. One clonk of the Permagrit or s
and paper and it is ready to go again.
It also dries fast so is ready to sand at the following day (given a good t
emp and dry air which during a Scottish winter meant using a heater and deh
umidifier).
The sanding process was huge as we made the Classic wings from starting fro
m foam shapes. The Superfil made it a lot more pleasant and the aircraft we
ighed a lot less at the end.
We did it ourselves using their entire Top Gloss paint system to very good
effect.
Just my pennyworth.
