Per MIL-STD-2073, 'Items shall be treated with appropriate preservatives in accordance with procedures of 220.127.116.11 or 18.104.22.168. Contact preservative coated items shall be wrapped in a material conforming to MIL-PRF-121, Grade A, or QQ-A-1876. Flexible wraps shall snuggly enclose the coated part or item and be secure to prevent unintentional unwrapping. Parts or items coated with hard film preservatives conforming to MIL-PRF-16173, Grade 1 or 4, may, when dried, be exempted from wrapping. Items preserved with VCI treated materials conforming to MIL-PRF-3420 or MIL-PRF-22019, respectively taped or sealed to form an airtight enclosure, are also exempted from wrapping. Projections, sharp edges, or other features of the item, which may damage the barrier wrap, shall be cushioned as required in accordance with 5.2.3. The type of cushioning and barrier material used shall be commensurate with the size, weight and configuration of the preserved part or item. Method 20 packs shall pass the applicable inspection requirements of table G.I.'
