I’ve had decent success with the Krylon Premium Metallic line Premium Metallic - | Krylon
But I think brand of paint is only 5% of the outcome, the quality of finish is usually dependent on how well you’ve primed and sanded the WSF print and how well you apply the coat (ie. light misting coat layers that slowly build up to prevent runs which look especially bad in any metallic because of the metal flake).
The smoother you can get your model (ie. reduce small details) the more likely you’ll get a result that looks passable for metal, but if you have a lot of small detail adding paint will only make it look rougher.
Another option is potentially printing in Alumide http://www.shapeways.com/materials/metallic-plastic doesn’t look like typical dinnerware but might work depending on your aesthetic.
