IS THERE A BETTER EPOXY?

[tailgrabber]

I am from Pa, Haven't gotten to fish the westcoast yet. I use the locktite 2 part epoxy the one in the seperate tubes mostly. But I have also used the kind that come in the seringe, and about 60% of the time it doesn't harden right. I would say maybe it is a climate condition, but if I epoxy 4 at the same time atleast one won't harden right. And you know it's always the one you think will work the best.
