I don't care what anyone says, it's still not a lubricant. It is good
for first-pass cleaning of greasy parts, or displacing water from
distributor caps. It is not a good lubricant.


You made 2 statements. I would have agreed with the first, "it's not
a lubricant", a few years ago. WD-40 even had on their label "This
is not a lubricant" But now their label says "Lubricates. . .
hinges, wheels, rollers, chains, gears"

So either they changed their definition of lubricates-- or changed the
recipe.

You other statement "It is not a good lubricant" might be true--
especially in the OP's case where there are products designed for
sliding door rollers--- if lubrication is really what they need.
