3/4 Balsa Core = X/X Plywood

What is the deal with marine foam costing so damn much. Water resistant Rot resistant regular foam a possibility? If not then please someone point me to the local source for said material bc it has to be cheaper than getting it from Jamestown Distributors

Having had decks made from balsa and also Airex, I'd go with marine foam. The costs are a fraction of what's involved and yor labour etc.
