Hi Thomas, Basically I've come to the same conclusion as "Om G" above. I think the material is way too heavy & dense to use for a surfboard - among other things. If you have any ideas or suggestions, I'd love to hear them. Thanks!
Thanks for your comment. I didn't realize the foam was not already separated! I'm curious to know what method, materials, adhesives etc were used on the Nike Grind running track & athletic/play flooring already being produced? Do you know? I figured that would be a good place to start.
