I have a fireplace insert I'd like to put a new surround on, but before I put the surround on I'd like to make the metal insert look a little better. The face of the insert looks like it's got a baked enamel paint (black) as a factory application, but it has some scratches that I'd like to cover up. I realize that the face of the fireplace is exposed to high heat, so I don't want to use any old housepaint. So my question is; can I apply a new coat of paint, and if so, what kind of paint can I use and how do I apply it? Thanks in advance!
