I was told by the shop where i bought my resin, and by the manufacturer (Gelcote) that the ratio is 1:100. I was mixing batches in 2 cup batches and used 1-1.5 teaspoons of hardener. That is technically mixing a little hot, but since i was working in +1 degree celcius, I needed it. should be about 1/2 teaspoon to every cup. (enough of this counting drops crap)

It's on 1-3%, 3% being on the "hot" side but is the max b/c above that it will get rubbery.
