Well I used it many times when Silicone grease was not available. It does
not work as well on bolts, but still better than nothing. does tend to run
out of a joint though.
Just don't go to Wallgreens at 12 PM to grab a jar and a pack of D cells. No
one will belive your antenna got blown down and your flashlight is dead!
