Over the years I have used many types of coating. Paint, patina’s, varnish, ink, dyes and powder coating. I like the choices of colors in powder coating very much. I like adding textures to metal in this case aluminum rather than paint. In powder coating I find solid  and transparent  very effective. Currently I am working on making five large aluminum perforated bowls and sixty three plus small aluminum perforated bowls. As it is spring I will look for spring colors.
