you can try that,but...
polyester bsed resins,contrary to popular belief are not the best choice when working with wood
epoxy is allways the best choice...
a smart choice is to use composites - a quality composite like penske/coosa board will give you a core that will last,versus wood.composites,a quality composite is allways a better choice...
