So I received my Stove Bright Metallic black spray paint yesterday and I am going to touch up my door after work today. For those of you who have painted cast iron before, are there any tips you can pass my way? It is a door on my Regency insert that I believe is cast iron. I am going to take the door off and newspaper the window off so I dont get any overspray on the glass. I also was going to wipe down the door with some acetone to remove any oils from handling it.Thanks for any tips
