The current resin that is to be used is the West System 105 Epoxy Resin (http://www.westsystem.com/wp-content/uploads/User-Manual-2015.pdf). It has a viscosity of 1000 centipoise, very thick for the vacuum infusion process. However this can be compensated for by the resin hardener used. The most likely hardener to be used is the West System 209 Extra-Slow Cure Hardener Hardener. This has the following characteristics:
- Physical properties not an issue
- Just have to make sure watertight!
- Otherwise consider fiberglass first
