How much epoxy is needed for the construction?
This is a difficult question – which is why I didn’t specify it in the actual pages. The exact quantity depends very much on a number of factors, such as the care of the builder, the thickness of the fiberglass cloth used, the absorption of the wood, if you decide to put some cloth inside the kayak (like I did) etc. That said, I think you will need a minimum of about 5 liters (1.5 gallons) of epoxy plus its accelerant.
