How's it going? Sorry for the newbie questions. I tried searching but no help. I'm new to the forum and just acquired a General Air Corp fridge and I have a couple questions. 1: Can I use/leave the original insulation? Do I need to take the interior down to bare metal? Can I leave the original coating, or can I just sand it and paint over it?. Thank you for your help, and I look forward to finished my build!! Thanks for your help!
