WD-40 was invented to be a water displacer. WD = Water Displacer. It is
great as a cleaning solvent and does provide a protective coating to help
prevent rust, but is not a good lubricant at all. There are quite a few
silicone lubricants on the market that are sold as lubricants. I have some
jeweler's oil (very light oil) I have used to CLA shutters.

WD-40 is not a very good lubricant. Liquid Wrench is a better
penetrating oil but where things are a bit stiff sometimes a
small amount of naphtha will dissolve the old lubricant and
loosen it up. Follow that with about 20 weight machine oil. This
is available as 3-in-one oil in the BLUE can. The RED can is the
familiar penetrating oil, again not a good lubricant. The Blue
can stuff is good machine oil. Where you want to control the
amount I found applying with a small artist's brush works well.
The oil, by itself, may work.

When I got my Technica, most of the movements were a bit stiff or
frozen. I suspect it had spent many years ope, just sitting on a
shelf. I gradually cleaned it using very small quantities of
petrol, terps, acetone and whatever other likely solvents came to
mind. It took a while. I then lubricated it with wd 40, which, at
that time, I thought of as a magical universal lubricant.
It now works fine, but I’m not sure that I would adopt that she
cavalier attitude to the restoration as I did back then. (it was
pre-internet… when you still had t use books to find things out!)
