I Have my old fridge at the metal shop having the inside of the door finished out as well as the trim. The inside of this old fridge is metal with a porcelain finish. Is there, or what type of paint can be used to cover the raw metal on the inside of the box and possible the entire porcelain inside, or do you just let the smoke do the job. I have pics posted on another thread here and more to come as we progress. I would appreciate any and all help. Thanks and a great day to all.
