After reading Pat Weston's suggestion to use Jeffco 3176 instead of the standard hardener, I checked with the company to see if the offered it. They replied that they did not carry it and had not officially approved its use because it did not pass one or more of their (I'm sure stringent) tests. Does anyone have any other information about the use of this hardener or any alternatives that have a longer pot life than the standard hardener?
