I actually wanted the regular MGEX Strike Freedom, but it was so hard to find that I happened to get my hands on the Mechanical Clear version, and that's how it all started...
The Mechanical Clear version is good for showing off the frame, but I still wanted color separation, so I set my sights on Bandai's bizarre backing molds (which are hidden in the regular version), and that was the beginning of my downfall...
I discovered a paint that's transparent but glows under black light, and I thought, "Wouldn't it look cool if I used it for panel lining?" It was such a stupid idea...
It was incredibly difficult...
The paint had a bad habit of sticking to it, and wiping it off after pouring it into the molds was really tough.
