These procedures shall not release the contractor of any responsibility for disassembly and meeting the minimum requirements for long-term storage. To ensure thorough cleaning of the items, varying degrees of disassembly are mandatory. In normal atmospheric conditions, these procedures shall provide interim protection for 180 days. After 180 days, the equipment shall require additional cleaning and preservation in accordance with sections 4 and 5 herein.
4.5.1.4 Interim storage. After the IPE has been cleaned and preserved, all items shall be placed in interim storage to prevent deterioration. A protective dust shield or cover shall be provided for each machine. Dust shields shall be manufactured from waterproof barrier material conforming to type I of MIL-PRF-22191 or class E-2 of PPP-B-1055. Electrical and electronic equipment shall be enclosed in barrier material conforming to type I, class II of MIL-PRF-81705 or approved commercial material.
4.6 Fingerprint removal. After cleaning and drying and prior to the application of preservatives, surfaces shall be treated for the removal of fingerprints and other perspiration residues utilizing a compound conforming to MIL-C-15074.

4.8.1 Preservation of painted surfaces. Where an excessive amount of paint is missing or there is damage to exterior surfaces, the item shall be touched-up or repainted to prevent deterioration of the surfaces. The color and workmanship of the paint application shall be such that the appearance of the machine is enhanced as much as practical. The choice between touch- up and complete repainting shall be made primarily on the basis of economy.
4.8.2 Preservation of unpainted surfaces. A preservative compound shall be applied to clean interior and exterior unpainted surfaces in accordance MIL-STD-2073-1. The preservative compound shall conform to the specified class and grade of MIL-PRF-16173. Care shall be taken to preserve only the required surfaces with minimum overlap on the adjacent painted surfaces.

MIL-PRF-121 shall be inserted with a double fold at the points of contact. The barrier material shall extend approximately one-half inch beyond the edge of the blocking material. Barrier materials shall be secured in place with tape conforming to ASTM D 5486/D 5486M.
