Looking foward to seeing the results. About two years ago we built an addition to the house. We had an old cement double sink on the back porch with rusting metal legs. I had the legs sandblasted and then took the to a local powder coater, who had a metal gray color we used on them. I think they were cast iron, or maybe a pot metal. The came out great, and now we don't worry about them rusting(1880's cement sink)
