I've heard that stainless steel foil is used to wrap metal parts when heat-treating them in a furnace, to keep out oxygen. I wonder if it would be a better alternative to aluminum foil for holding water? If the SS foil can exclude oxygen it probably does not develop pinholes when folded. Anyone with access to this stuff want to give it a try and let us know how it goes?
