[PSUBS-MAILIST] syntactic foam

[Alan via Personal_Submersibles]

Hank,
I wonder if you could use a combination & cast the foam
around & over the trawl floats. It would give a nicer finish & 
attach the floats.

There is syntactic foam available that you mix together into your own mould also.  I am also still woking on the titanium spheres.   I have time to sort it out.
