J.T. has been telling us for years that chrome is thin. I don't think it's news to anyone. He always leaves in a huff. I guess you could say that's his style.

Simichrome (not semichrome) is a metal polish that can be used to clean and remove surface rust from chrome. It can't polish chrome. Chrome is too hard. it does a great job of polishing softer metals like aluminum and brass. So do a lot of other products.
