The thing started because in my country Hasbro didn't import Cybertron Galvatron, but only Megatron. But I liked most Galvatron's colors, and to buy a Galvatron from ebay would be too expansive. So I bought an ordinary Megatron and fully repainted it I use a silver spray coat, then glossy acrylic black (Model Master), Blood Red, Brazen Brass and Mithril Silver (Games Workshop) and some coat protection with Gloss Clear (Model Master). I think it will need some touch up and maybe another coat with sealing spray. The most difficult parts are the rubber ones, because paint don't attach very well there, and especially when transforming, the paint crackle or simply rip off.
