I know this is like the 45,000th Leader Prime, but Im just now getting to mine. Gunship grey enamel mixed with gunmetal black enamel for the basecoat. The rest is a mix of acrylics & enamels (Testors blues, Tamaya reds, model master chome/silver, gold acrylic & enamels) Also painted a few robot sections metallic blue, to have truck mode shell parts break up the robot sections a bit. Finished off with some wash (mars black) and coated with testors clear coat. He's now up.....on my shelf thanks for looking!
