<DIV><FONT size=2 face=Arial>These are great questions. The one thing I have
seen is that the hardener doesn't have a really long shelf life after it's been
opened. Depending on how you store it (cool storage areas are better), it
seems that it can degrade in as little as a month after opening. It still
works, but the gloss seems a bit diminished and the surface hardness takes
longer to develop. That's what I've seen at least. It would be
interesting to see if anyone has found a way to make it last longer, for example
would real cold storage work?</FONT></DIV>
