Hey, I saw that you were using Ral Partha's unfold of the model, try pepping Brandon's instead... I came to that conclusion comparing the pictures with both files.
I'm still gonna pep that part if Brandon's unfold doesn't work....
OH and are you keeping the helmet outside to cure? If so it's probably just the wind screwing it up... I suggest putting the helmet on a stand close to a wall and building a four wall shield from a rather large piece of cardboard by cutting it in squares and hot glueing it together. Make the box as tall as possible to avoid wind coming in from the bottom of the box... It's just a theory, it may not work. Just try and tell me if it works or not, and I'll pep the piece and resin it when I get some to see what's wrong.
