C.G. - "Copper Grease".
If you have had the experience of working on a LOT of cars in the past, then you will totally understand where this is intended to be applied in relation to brake pads.
I am not getting into this debate folks, if you know, you know.
If not, leave well alone for safety sake.

I know full well what Copper Grease is, just haven't come across anyone bothering to abbreviate it. What about OBTW ?
