Woops, I just noticed that my reply was to Dellmer since his response was
directly to me and not through the listserv. Let's try that again.
------------------------------------------
If the Flex Coat has been at more than about 65 degrees F for greater than
about 20 hours and it's still tacky then temperature isn't the culprit. The
problem is with portions that were wrong and/or not well mixed. Yes,
temperatures below 65 will cause problems but I have finished many rods at
65 degrees - I actually prefer it as it extends working time.
You're on the right track Mike; another correctly blended coat on top of the
tacky coat will normally fix the problem - it will catalyze the underlying
coat. A common misconception is that epoxies dry by evaporation. They
don't dry (relative humidty has almost no effect.) Actually they setup by
an exothermic reaction - like cement. That's why there's no reason to think
that the non-hardened underlying coat will trap moisture. Don't worry about
going extremely thin as that will only allow previous imperfections to show
through; and if there are areas where the new coat is too thin it may not
cause the underlying coat to react. Use a normal coat (thick enough to
level) and temperatures around 70-75 degrees and you shouldn't have a
problem. I would recommend against the Sally Hanson's hard-as-nails
approach. It's great for head cement but not I don't think I'd mix it with
Flex Coat.
good luck,
Keith

Temperature does affect the hardening process, maybe if you would warm the
wraps very gently with a hair drier it would help set it. I always put mine
in a heat cabinet no matter the time of year.

> Hey guys, I am in a bit of a jam. I have to deliver a custom rod on Sat
and my Flex Coat is making my life difficult. My first coats went on okay
but my secon are either tacky or really slow to cure. I know this is a
chemical reaction vs. heat but does cold weather slow the process down? It
has been chilly here in Eastern, WA this week.

> I am going to try putting a very, very light coat on the tacky wraps
tonight in hope that maybe my mixture was off or didn't get mixed all the
way last time. If this fails, any ideas on what to do? I have read some
people using products like Hard as Nails to force tacky Flex Coat to cure
but have no experience in this. It is a special Christmas present for this
family to their son so I need to get it done ASAP.
