I purchased Robby a few months after he came out and also looked at some of the fine examples of him on your site. I tried to do the paint mix the way it was explained but I thought he looked too blue. So I went with straight gun metal gray. I used the neon paints for the voice coil and lights on Robbie’s chest and brain as I saw on your site a while ago. I think that was the right touch short of lighting him with fiber.
