Lets keep this thread going!
I'd really like to go as the man of iron for halo-ween this year.  
I know I know, I haven't finished my 117 armor yet, but this is uncharted territory!  From what I've gathered, this would be a great suit to vac-form, but I think I'll stick to what I know so a hybrid pep / molded armor suit.  
Now to just secure financial backing and a keener knowledge of seans "mud" technique.  
Bring on the IronMan Pep!
