Wow great clone! Love the clean apps
I haven't been able to get the upper arms out of any GI Joe stylee two part Clone body just by boiling and popping sadly, i've had to use the boiling water to soften the actual torso and the shuck it open under the arm pit (like an oyster!) with a craft knife.
It is something to do with how the shoulder join works - I have the same problem when using Joes... Sorry mate I didn't make myself clear
