27、6. NOTES6.1 Intended use. Gun slushing compound is intended as a corrosionpreventive for ferrous and nonferrous metals in indefinitestorage andin outdoor and indoor use. It is applied hot in thin coats by brushingor dipping. It is soluble in commercialsolvents, slow to dissolve,especially in cold w

28、eather when used outdoors. It is usually found moreeconomica1, in both time and material, to remove the compound by steamingor scraping. The compoundwhen applied over clean surfaces providesexcellent protection.6.2 Ordering data. Procurementdocuments should specify the following:Title, number, and d
