Would single stage urethane be a good paint for a dark brown metallic? I'm trying to decide bc/cc or single state urethane. From the factory it came with acrylic enamel. It will be professionally painted. The shops tell me bc/cc especially for metallic paint. But I think that is because it is easier to paint bc/cc. I've read that darker metallic colours can work well with single stage urethane. I'm going to talk to a restoration shop. Any advice?
