Thanks, I needed to hear this discussion/advice. I was perplexed from the faster depletion of my resin than the hardener, considering the 2:1 ratio. I used the MAS dispensers, and had to order more resin before the hardener was 85% gone. Idid not have too much problem on the curing except for the bow end pour, which took 2 days (in relatively warm weather) to cure hard enough to return the yak to its cradle. The birds were starting to nest in the cockpit and the neighbors here in this Cinti suburb didn't know what to think of their eccentric neighbor. I will not rely on the dispensers alone anymore. Coating the deck is next and this discussion was timely. Paul C.
