Ok, I know it's been done to death but I've never given it a shot with the Movie figures and finally got my hands on one:
Random Iron-Man Movie Figure
Nemesis Punisher Head
The figure didn't have any shoulder pads, so first things first I sculpted some. Modified the neck joint to more easily allow swapping of heads and then the rest was just a careful and brain smelting paint job. Clear paint is the messiest stuff in the world!
