I wouldn't buy anything specific. I don't know if there is one specific? I use an anti-sieze, can't be sure of the brand, this last time the can was out of reach but regular grease wasn't so I used a smear of that. I can't imagine it's a huge deal what you use, a little of something, just a smear, too much and your risk it getting really hot and getting on the rotor/pads or igniting?
So I commuted in the X this morning. Felt nice, no shaky and tracked straight, have to assume I did at least a passable job with alignment last night.....okay, it was really in the wee hours of THIS morning. Brakes still dive left for a split second and then even out. Next step; hoses. Then, failing that I'll go after calipers.
