Prime was harder do do than I had originally thought. I had to disassemble the cab to remove his head and to also get at the detail in his chest. I tried to match the blue used by Hasbro and I think I came pretty close. He was given an black undercoat and drybrushed with steel and aluminum. I got some detail stickers from Reprolabels.com. I had to remove his electronics because they got damaged trying to put him back together. Let me tell you, it ain't easy.
