There is another 'problem' that may have happened to you.

I know that it has happened to me and some other rod builders.

Sometimes the product are improperly packaged and you really got two bottle of resin and no hardener. The hardener is a different color, at least with all the Flex Coat I have. If yours isn't, then it's possible you got all resin with your 'kit'.

If everything you posted is correct, then I think this may be what happened.....
