Metallic paint by roller/brush
 

I want to (or, at least, I think I do) paint a room in my house a metallic medium/dark grey. Is this possible? If so...how? It'd likely be applied by roller, with brush around the edges. Thanks.

Home depot sells some metallics now that are applied with rollers, etc. I have never used them, but I do have a quart of copper in my basement (plans changed)

Really? I'll just have to go check that out. Thanks.
