So Monday morning I discovered one of our freezers had quit working. Luckily I found it before the meat had thawed much and got most of it transferred to our other freezer. We bought another freezer the next day and it was delivered the day after that. The old freezer was supposed to be hauled off when the new one was delivered but the delivery men refused to take it because it had been sitting in our garage, exposed to mice, spiders and such and they didn't want such things getting in their new appliances. Quite understandable. Anyway, they moved it out on the patio for us and a couple of day later as I walked past it, it occurred to me that if it were buried it would be a great storage place for food, ammunition, guns, and 19 cu. ft. of other preps. My question is, what should I wrap the freezer in to help keep it from rusting, and should I line the interior with something? Would mylar be a good material?
