I'll stick with what mrblaine uses and I did follow his recommendation to use anti-seize (not liberally but conservatively).
After having to remove thousands of galled stainless screws, no such thing as just enough or conservative…they need to be dripping with it…I hate engineers who spec stainless and especially stainless on stainless, most horrible thing to ever have to disassemble. Most stainless hardware is softer than grade 8 and a good passivated zinc will last decades.
