Epoxy and Fiberglass
For epoxy, I have been using System Three in 7.5 gallon kits, which I purchase from Fiberglass Supply. My low-tech measuring method is to use mixing containers from the local Tap Plastics store, which have the 2:1 mix ratio graduations printed on the side.
The bottom fiberglass is 10 oz. and secured with tape prior to epoxy bonding. The darts and extra glass at the bow curve were simply cut and folded over the the other side for additional thickness, so much of the bow bottom has a total of 20oz of glass.
