Query: Simichrome

As a metal artist, I've tried many products on the market for polishing metal. I find Simichrome and MAAS metal polish to be some of the best. It will even polish lucite or plexiglas, since I make brass salad servers with Lucite handles, and the metal polish is the only thing that gets both materials nicely polished. I find tarnish to be less a problem and the metal retains it's showroom finish longer, which is a plus when I do trade shows. Yes, there is a lot of elbow grease required to get a nice finish, but handpolishing metal on a buffing machine also takes a long time. I find the metal polish to work well on the areas I couldn't mechanically buff smooth. Metal in general is always going to require cleaning and polishing to keep it's luster and I'm thoroughly sick of working in copper now.
