Having been in the trade for years, and involved in the Aircraft industry too,this stuff is a great help.

Works very well on cross head screws, like on door lock plates and hinges.
Another tip is to use course valve grinding paste, similar the EZ Grip, just add a bit to the screw head.
Works well, especially with the screw knocker tools.
