Hunter,
I used the E6000 on my AP kit and had trouble at first. The trick is to be VERY patient... sand each part to be glued, apply a liberal amount of E6000, and clamp tight. Leave it alone for at least 12 hours. Any excess is very easy to cut and peel away like rubber cement, so don't worry about making a mess.
If you do one piece at a time, all should hold well. My entire armor has held together through many troops.
Good luck!
