While I was on the subject of spraying things black I also cleaned and sprayed an old cast iron clothes iron and a large 7lb weight. The iron goes nicely in the laundry room but I am not quite sure what to do with the weight, a door stop perhaps.
Finally I sprayed the two things for taking boots off (I don't know what they are called, boot pulls perhaps). Debbie got them for us when she worked at Thomas Dudley (famous for making drain covers and toilet cisterns) and they are cast iron. I have Mr Pickwick and a beetle.
