Check out this long term test, mainly aimed at rust prevention but awesome.

G96 Treatment !

I am a fan. Unrelated to lube of an AR -- I shoot a lot of sporting clays in the summertime. G96 is by far and away the best product I have found that prevents rust from sweaty hands.

I am partial to the G 96 products. The synthetic or bio both work well for me.
