I know what you mean about moving away from the polyester stink! I personally prefer epoxy for that and it's increased strength benefits.It is best to glass in temperatures in the 70's but I have glassed plenty of boards in the 40's simply by heating the resin component in the microwave to reduce the viscosity so it saturates the cloth easily. Epoxy is temperature sensitive and will take longer to cure in temps below 70 and cure faster in temps above 80... We recommend using Resin Research 2000 Ultra for your first time as it provides a good 25 minutes of working time - (Resin Research Quick Kick formula cures faster)
