Let me translate for sydney: grease on a fastener with a threadlocking compound negates any benefit from the threadlocking compound.

Yes, that's what the blue stuff is (and here you thought it was an alternative to Sweet & Low; don't listen to Cher, she doesn't ride).

I've never seen any white stuff; are you perhaps from Miami?

As to how horrible grease on the rotor bolts is, who knows? but one thing I don't f*** around with is brakes; I'd pull them and reinstall using only threadlocker.

Beeswax..?
