Do NOT paint the inside of the firebox. You don't want to eat those fumes. I would blast and paint the smoke chamber and leave the firebox bare and just oil it down well. There really isn't a paint that can withstand the kind of heat that a wood fire kicks off and you will be repainting the firebox forever.......
