Research and patience was what I learned the most with this build as it took me three months to finish.
The helmet was a custom paint job by me using Matthews paint,
The liquid metal bullet holes I sculpted out of clay, then made a silicone gang mold of the three sizes, cast out of resin and painted with Dupli-Color Chrome spray paint. ---the bullet holes are attached with magnets so I can move them anywhere I wish,
The spike for the left hand I cut out of a mirrored plastic material from a cnc router table and glued together the four triangles to make the spike,
Everything was sourced and ordered on various sites (amazon, eBay, etc...)
