[Milsurplus] Penetrating oil test - Youtube

[Hubert Miller]

I have been puzzling, and kind of dreading, how best to approach frozen setscrews in an old
radio. As if that isn't enough of a challenge, the frozen setscrews ( grub screws ) are in positions
difficult to reach with any tool. What fun that will be. So this little video was of some interest.
