anyone try OSI foam?

[restosud]

was at a norandex branch and noticed a display that demonstrates the OSI pro-foam.
it's a one part closed cell foam that seems a bit springy once dry,low expansion pressure and holds back water. the display was using this foam to form a cork on top of a small container filled with water.shook it and pushed on it a bit with no leaks.
has anyone tried this product for the tray?

went back to check it closer.seems the edge (1/8" or so)near or immersed in water is slightly different color due to possible water migration.gonna call rep and find out.
