I am new here but have been reading the forums for awhile now. I recently obtained a stainless steel refrigerator that I would like to convert to a smoker. Unfortunately it has the foam insulation so I am in the process of pulling that out and replacing it with Roxul. My biggest concern at the moment is the inside of the cabinet... It is aluminum, do I need to be concerned about this? Replace it with SS sheets? or will I be fine? I would like to use for both cold smoking and hot smoking. Thank you for your input!!!
