I would agree with the other guys....it's "panel paint", with a satin clear.

With nostalgia schemes dominating the hobby, this is a breath of fresh air, but still a similar way of thinking. The flat finish gives a more contemporary feel to what is a classic custom paint style from the late '50s-early '60s.

I like it with the exception of the bright green color choice. That is why it's a little on the obnoxious side....but maybe the owner or painter likes it that way, and it's their project. Even being over the edge, it sure beats "look-alike" paint jobs!

A little research and you could have multiple examples, to help refine your own design.
