We call it Wanton Destruction 40 round here for a very good reason. It's
a mix of all sorts of viscosities of lubricant, including some waxy
stuff. The problem is that the thinner oils evapourate first leaving the
wax to gum things solid. You then have to do a complete strip-down and
clean... I've seen the result of spaying it on the shutter mechanism of a
camera -- one day I'll take it all apart and get it going again. That's
what it needs....

I must keep a couple of dozen lubricants from watch oil up to about half
a dozen greases (and grease and oil for plastics) here...
