I had this junker Armada Megatron that I got in an ebay lot, and I actually like the mold quite a bit but hate the colors. I was inspired by a single panel in "All Hail Megatron" to do this custom. Krylon metallic paint for the gold. Some gold paint marker for touch-up. Some grey parts were dyed purple with Rit clothing dye (check my other customs for more of this). The gold spray paint I figured was a good approximation for his beige in G1 but then I got to thinking that it's sort of flashy. And since this guy has no jet mode he can't be Blitz*wing* so I was going to call him just Blitz. Now I am undecided between Blitz or Blitzbling. Hope you like.
have you considered modding him through the lower arms so he can use a energon jet lib figure as a jetwing shield ala g1 overlord?
Very well done. I think the only thing I would do different is the head, but the paint apps are spot on.
