When I got my hands on a casting of the T70 robot from T2-3D I was very excited, since I really loved that attraction.
Since some parts were missing to build a bust, the neck, pistons from the back of the head, face pistons and eyes were scratched.
After filler and sanding, the whole thing was painted using a military 2K paint and weathered with an airbrush to resemble the ones seen in the auditorium.
