I'm still incredulous. The deepest depression that I needed to fill was
---From damage in transit (probably on the truck, not the ship) to the factory
moldings, and these were more like 0.025 inch or 0.6mm deep, in other words
about one-tenth the "recommended" filler thickness. As for the foam core
surfaces, the manual says "...simply fill the weave of the cloth" and
advises to "Apply it (the filler) just thick enough so that you can not see
the weave through it." Even more to the point is this comment "As you sand
away the filler you will eventually (or quite quickly if you did not lump it
on thickly to start with) see the weave of the cloth appear."
My bonded joints to the factory moldings were the most difficult to get
right and did require several applications of filler, and although applying
a really thick first coat would have resulted in somewhat less work, it
would also likely have resulted in having more filler remain after sanding
(ergo, more weight).
But, hey, I'm just a novice, never having built an airplane before and
working on my first fiberglass project.

> 1/4 inch (6mm) thick??? Surely you jest.
On the 1/4 thick topic, yes that was correct. Neville was right, at the end
of the day is was far quicker to sand off too much than muck about with
applying second and third coats. If you mix it up really dry like he
suggests it does come off fairly quickly. I used a plane to rough it down
and then sanded it with 80 grit paper.
