Back when I used to carry lubricants in my range bag I would lend my
BreakFree CLP to shooters who had just disastrously found out their XYZ Super-Slippery Stuff failed them.
In the heat / rain / snow / dust / cold.
We'd apply it to their lubricated-but-failing firearm and get back to shooting.
I have a bunch of other very good gun lubes on my bench (Corrosion X comes to mind, as does my now-banned-formula Prolix), but when I reach for a lube I grab
BreakFree CLP.
I keep two pin-oiler bottle (available from www.Brownells.com) on my bench; one holds BreakFree CLP, and the other Prolix.
