My first real job about 40 years ago was a QC technician with a government contractor for military lubricants. Jet and helicopter hydraulic fluids and lubricants, and LSA grease. The test standards for LSA were very stringent. A whole battery of ASTM tests for metal friction and corrosion were performed on every lot, then the results inspected by Uncle Sam. One test was to coat a sandblasted carbon steel plate with LSA and place it in a high temperature, high humidity, salt water chamber for one week. As I recall, when complete, if you were able to count more then 5 spots of rust the size of a pin head or larger, it failed. I tried this test with some Outers Gun Grease that was a common product of the day and the plate was totally rusted in 2 days. I didn't even bother trying it on the friction tests. I used LSA on my 45ACP's when I shot IPSC. Good stuff!!!
