Paint Aluminum rims?

I was just wondering if paint sticks very well to aluminum rims that have kind of a rough surface to them? I just saw a pic of a truck with 33's on it with black rims.. really makes the whole truck look better and the tires look bigger too. Was thinking about doing mine the same way. How do you think it would turn out? I honestly think it might look kind of dumb with the big holes in the wheels... Pic here:
