Ralph Lauren offers a metallic paint you may want to check out. It comes in many colors however it is extremely difficult to work with to get an even finish. Follow the directions as it goes on differently than other paints and requires its own roller. If you are talking about painting brick, you should prime it first if the brick is raw, and if it is already painted check to see if the existing finish is oil based or not, as the oil based finish would need to be primed to convert to an acrylic finish. If you are talking about painting a mantle that has curved edges, I would not use this product because it does not brush out well. Anyway, it is just paint and can be painted over if you don't like the look.
