Foam ?

[Neil]

Ok, I am restoring a hovercraft, not a airplane, but the techniques may be
the same....I hope.
I have to bond foam into a existing fibreglass shell, to support the
fibreglass, and to make the unit float in water. The original builder used
canned foam, with pretty poor results. Any ideas?
Thanks in advance
Kim

No, no, no, you dunno wanna do dat! The two part foam will absorb
and trap water (holding it forever). Been derr don dat!
