Norfolk Southern are painted black...but which one?

Mark, what I'd do is strip the shell in alcohol to remove the current red and grey paint. The problem with black, especially gloss black, is that when light hits it, it'll show whatever is underneath, so you'll always end up with a line seperating the former colors I am afriad. I would definitely recommend a primer coat, but only after stripping the shell so as not to have too many layers of paint, obscuring details. Then apply a nice even (1) coat of gloss black over the primer coat and you should be all set.
