I've just finished sculpting the Iron Man mask from the new movie and I'm wondering what the best way to cast it would be?
I've spent so much time sculpting, I don't want the mold to be lost if I make a mistake - leaving me with one bad pull and plenty of frustration.
I'd love to vacuum form because it'll enable me to make numerous copies fairly inexpensively, but as you'll notice from the photos (link below) there's a few vertical surfaces (as the gold piece meets the red at the forehead). I'm affraid the detail will be lost because of how the polystyrene will drape.
I've considered resin-casting, but I need a hollow cast, and I'm not sure rotational casting is worth it.
*Note: FYI I'm constructing the mask in two parts, the front and top half and the rear piece ending around the ear area.
