I forgot what's the name of that stuff to increase friction on screws and nut

A month or two ago there was thread (which I cannot find) about friction material to put on a screwdriver or a socket to increase friction to get loose stubborn nuts, bolts and screws. Either link me up the thread please or tell me the stuff you guys are using.

The stuff discussed in MCN magazine is Bit Biter by Tectorius, phone 586 232 3999.  it's just a mixture of a liquid carrier and some very small grainy hard stuff.

Align-rite Screw Grab was the stuff on this board.  I bought a bottle at that time, used it once and it works good.
