I found that warming the epoxy tubes in a bowl of warm water, will help with the mixing, and the penetration of the thread wraps. I keep the tubes in the hot water bath between mixing, replacing the water, as the temperature drops.

There is a tendency to apply more epoxy, then called for, when coating the wraps.

Less epoxy is better, then too much epoxy. You can always do another coat (if needed), versus, either living with a mistake or ripping the whole epoxied thread wrap off the rod. ~Parnelli
