        <div>Brian, I have been tied up and have not had a chance to follow this thread but I wanted to make sure you understand that unless this pour-able 2 part foam has a filler like 3-M's glass micro-spheres or some kind of incompressible macrosphere, then while the foam may appear rigid, it would compress when subjected to deep water and thus your buoyancy would be reduced.   I don't think this is a replacement for syntactic foam if that is what you are doing.  Can you send a link to the foam you are using?</div><div><br clear="none"></div><div>Best Regards  </div><div><br clear="none"></div>
