Picked up a Cast Iron bottom gate T Kettle the other day. The photos did not show the scratches, or that the lid had a couple coats of black paint. Did not look good at all as a display piece so found a striper that is taking the old paint off to bare iron. Short of engine black paint what would be a good way to blacken it again? Only one I remember was Mothers old metal T Kettle, tin or aluminum. Only markings are the number 7 on the lid and back side of the spout.
