[Public-List] Lubricants

[Gordon Laco]

Interesting stuff Mike -

I had something about WD-40 explained to me that you folks may already know,
but I didn't. 

Once WD-40 has evaporated, there is virtually no lubricant left.  In fact,
WD-40 will rinse off grease or thicker oil leaving what no lubrication
protection at all.  It should be considered a 'momentary' lubricant.

I had this explained to me in context of a car door lock I ruined by
injecting WD-40.  What I'd done was rinse out any lubricant that had been
present leaving no protection at all.

Interesting stuff.
