If the epoxy isn't dry everywhere, can you guess the reason? When you mixed it, did you mix completely? Was the ply a bit damp?
How long has it been since you layed on the epoxy? I would try a heat lamp on the sticky areas, and if the other side of the ply is bare, a bit of heat there too. Give it time. Under certain conditions (cold, damp), epoxy can seem to take forever to cure.
If you cannot get it to cure, you have to cut it out. If you're not sure it will cure ever, cut now all the way beyond the sticky area into the good area. use a sharp razor, go deep enough to make sure you're all the way through, and peel it off. Clean the surface with acetone well, and tomorrow feather the edges around and patch over it. When that's sanded, the patch will feather into the surrounding area.

In my opinion it could be damp in air and mayby too low temperature. Epoxy was mix completly. I will try with lamps...
