: For closed cell you can also check local kayak stores - more and more of them
: are carrying it.

: Also - there's no rule that you have to use closed cell. You could use that
: blue home insulation foam that comes 2" thick avilable at home
: centers. Not as flexable as closed cell but cheap and if you coat the
: outside surface with epoxy, it bacomes very strong. The big advantage od
: C-foam is that you can squeeze a not-so-perfect fit in perfectly.

The first bulkheads I made were painted foam insulation. You could coat this material with plasti-dip(brushed on)..to give it a better feel.
