Ok, so I am in the process of making a budget for my brother and I's halo armour, only I don't know how much resin we will need so i cant get an estimate. He is about 6ft and having full halo 3 Hayabusa Armour. I'm 5'3 and having halo 3 Recon helmet, mark VI chest and scout shoulders. how much resin do you think we will need for either one set or both sets of armour?
