Rusted and oxidized tin backsplash
When we remodeling the kitchen in a Craftsman bungalow four years ago, we had a tin backsplash installed in the kitchen. It is now rusted in places and seems to have some oxidization in areas. We tried removing the rust with whiting and a potato. It helped some but it still looks bad. What should we do? Should we paint it? If so, what kind of paint should we use? Any advice would be useful.
