Spencer Chase mentioned "Kroil" for this project.  Kroil is one of the
best penetrating oils I know, and came to me very highly recommended by
a _real_ rocket scientist.  Kano Labs produces it, and does do direct
sales, as it might be hard to find in your area.  It isn't "cheap" and
comes two ways, "Areokroil" is Kroil in an aerosol can.  It's the most
common way for us occasional users to find.  It's in an orange can.
You'll really like it!
