What you have is better than acrylic enamel and is a good paint to use. It should hold up well but will be harder to paint than base /clear. The trouble is in getting the metallic to look even any kind of sag will show big time or it can look mottled if not sprayed evenly. Back before base /clear systems after painting metallic colors we could spray a light for of paint from a few feet away to even out any metallic problems but those paints were so slow drying it would melt in and not look dry. Sanding and buffing single stage metallics can also cause trouble as you are going into color coats not just polishing clear. If they will either exchange for what you asked for or at least sell at cost I would go for the base /clear. How clear were you in asking for base /clear is the question?
