Sil Glyde. Looks like a toothpaste tube. Available at any Autozone. Tube lasts the cars lifetime and IS the right stuff for slides. Permatex will also work but harder to find (at least around here)...Stuff is so good, we used to use only the SilGlyde at the dealer ditching the Honda OE stuff.
Do NOT use anti seize. Will turn to gum as soon as the brakes get hot, then you have a real mess trying to scrape out the gunk out of the boots. You "can" also use the SilGlyde as a pad lubricant. Use it sparingly but helps a ton with pad chatter and pad ear binding.
Basically what Tony said...
