Has anyone out there from Illlinois ever heard or had any experience with the businesses that redo the porcelain finish on cast iron bathroom fixtures? As in having the porcelain blasted off, down to the bare metal, and then the porcelain process was redone from scratch. If so, were you satisfied with it? I was told there is a company in Illinois that does this and was wondering if anyone knew which one it is? I googled it and found quite a few. I have a toilet tank that I might consider having done.
