Hi Tony
From past experience of expanding foam in house building projects I
would guess it is not suitable. Tends to have quite large voids left in
it after it has gone off. It also tends to keep expanding so very
difficult to judge how much to put in.
Be interested to know if any one has found a way of using it, I have
been meaning to fill my flap extensions for the last 12 years.

have found a tube that is tapered down to the OD of the flap cross tube, my

cleaner wand, and I have created a couple of tubes that I intend on placing
over the flap cross tube and re-rigging the wings, then filling the gap ideally
with expand foam or something similar, shaping it, and then glassing over
it, with flox corners and 2 plies of BID. Has anyone used expand foam to shape
things as it is a deep closeout now with the flap extensions on them, and to
make up foam inserts would be a bit of a disaster. I tried some expanding foam
today, upside down as instructed, and disaster. It managed to exude around the
base of the wand, not down it into my dummy setup, the inside of a tissue box.
So, I have a puddle of expanding cell foam on my bench that I can now see
if it is sandable and shapeable, or not.

it rather than have a chamber of air, requiring venting if I just create a wall
at the end of the closeout, somehow. Any tips??
