hey mike, not sure if you know this already, but a little trick i find to work on the vision blocks, (when you get to that point), is i use a small bag of party confetti. you can buy a bag od different colors in different shapes: blue, green, red, pink in stars, circles, diamonds, etc etc. i take some colors a\that are close to the actual color, and cut them to shape, and just glue them on. here's how mine went:
like i said, if you knew it already, kudos, if not, hopefully i can help a little. you can find the confetti at any wal-mart, michaels, or dollar store. it wont work so well on WWII armor since they didn't have the laser protection in it.
looking forward to seeing some more of the build, its coming along nicely
