I've heard of using MdS2 as an agent to keep punches/chisels from sticking
in hot work.  It is apparently a powder, would anyone mind sharing their
experience/ recipes for using this stuff?  Is it "better" than graphite or
coal dust, etc?
 Molydisulfide is used extensively as a lubricant by "cold headers", the 
people that head screws and bolts from coils of steel wire, especially stainless 
steels.  It is available in powder, paste and liquid.  It replaced copper as a 
lubricant for the same use as it is less expensive and much easier to remove 
after heading (dont need acid).  It is applied to the coils of steel wire right 
after degreasing by dipping the coil in a tank of it and then drawing it 
tight to the wire with a pass through a die.  Everyone seems to have their own 
recipe for making it, and you could probably get info from the Internet.  
Molydisulfide is real slippery and is added to all kinds of lubricants such as oil to 
increase its effectiveness.
