What is it?P.S. Wow, you're back.
hi joe,it is a natural sandwich composite i am developing in my master.it is made of PU (made from castor oil), core and resin, and natural fibers. vacuum bagged.the boat is coming soon.although it is still not 100% made from renewable sources, it is a lot less toxic.
Good progress on your Wa'apa. Very interested in the sandwich, so you have a foam and a fabric from natural materials? What about a natural resin! then we have a complete boat building system! Tell me more.
