Cyclo "breakaway" is also a good penetrant to use.

Also, a trick one of the old pros next door uses (especially on 
bleeders) is to set up the wrench (or 6 pt socket/ratchet for a 
bleeder), and then use a tiny hammer to rap the wrench over and over. 
It acts like a very low torque impact wrench, and increases the chance 
of getting the bleeder out instead of breaking it.
