Paul,
It took me 3 weeks' solid work , (mainly because I had a lot of small
defects, pin holes etc. I applied SP Systems hi build brushing primer
all over with a brush and failed to comprehend that you should use a
squeegee to wipe most of it off before it sets - I then probably spent 2
of the 3 weeks carefully sanding to get the brush marks out).
You seem to have listed all the joints you have to fill. Make sure you
use enough filler to make an invisible joint by placing a long straight
edge over all the joints to estimate the minimum distance you need to
fill to to eliminate daylight under the straight edge - then over-fill
slightly.
Neville recommended using a perspex car number plate to apply the filler
with and that was a good tip - it is sufficiently flexible to fair the
joint in well at the wing root fairing. I took this filling about 18"
into the wing to make a smooth transition to the fairing but that
depends on how tightly you managed to fit your fairing to the wing.
Neville also recommended sanding down the edge of the fairing near the
wing then applying a lay up of Bid tape over the sanded down joint, say
2" wide, to avoid cracks developing at what will otherwise be a stress
point at the wing step area.
Be careful in rubbing down though because the top layer of glass is very
thin and not far below the gel coat. You only need to break the gel coat
glaze - beware if you see slightly darker patches appearing because you
will soon be through the gel coat and into the glass!
You don't have to prime it because your paint shop will probably use a
high build primer - check with them first and if you do use SP systems
primer - spray, rather than brush, if you want to save time.

Subject: Finishing XS Wings
Hi all,
I am about to drag my XS wings down to the basement to fill and sand. I
was wondering from the folk who have gone before me how much work this
is. I am assuming that I only have to fill around the fairing, end caps
and glue joints, or do I have to prime and sand the whole wing? How
many hours per wing is this task likely to take.
Thanks,
