Closed Cell Foam is great for custom outfitting your kayak to fit certain needs. Whether it is making a customer transducer pad, carving new hip pads for your sit inside kayak, adding more flotation to your kayak, or for re-enforcing the deck of your kayak to be able to take a heavier load, the Closed Cell Foam can do it all.
I used this to line a road case to pack some heavy equipment. It worked the way I wanted, not compressing much under the load.
It's always a pleasure doing business with ACK . Top notch.
