Dan -

We were told that if the hardener for the Hysol (the dark blue, part B) gave off a strong whiff of ammonia, chances are it is over the hill. However, every one of the sets we get from Lancair has this smell of ammonia. Some are a bit more than others, but they all have hardened/cured. The question, then, is: to what hardness?

Any guidance or thought on that?
