Ever hear of this stuff?

[MikeC5]

I was on a business trip in Germany and the shop I visited had this stuff.  I observed (jet engine) mechanics using this where a screw head or bolt head was damaged during disassembly.  It did work.

I should have picked some up because it doesn't appear to be available in US.  I have no connection with the company that makes it...

Roughly translated:  

In the paste are small corundum crystals. When the screwdriver is inserted, 
they are compressed and make a connection with the screw. The friction increases 
and (damaged head) screw can be removed.

I've seen a couple similar products, but never tried them

Gotta love google translate:
Gives worn grips and tool grip and grip again. All standard screw types can be easily tightened or loosened with a screw-type grip.

For loosening damaged screw heads of all kinds, such as slotted, cross-slotted, hexagonal, hexagonal, multiport and torx screws.

Course valve grinding paste does the same.
