Also shy away from WD-40 as a general lubricant. It gets gummy over<br>
time. For slides look at a light grease, perhaps a white lithium<br>
grease like 3M™ White Grease commonly used on some garage doors and<br>
autos. It only takes a little....<br>
<br>
There are also Teflon based white greases and many excellent but black<br>
and dirty molybdenum disulphide greases. Moly rich grease is interesting<br>
in that the moly "plates" on the surface and if the tolerances are tight<br>
binding (not lubrication) can occur. On old cars however it can tighten<br>
up things if used sparingly. As much as I like moly greases I think<br>
a multi-purpose lithium based white grease from an auto supply house is<br>
the best choice in this case.<br>
