No, not "could be", it IS. The solvent in it is the degreaser, and the
oil is the repeller.

I use WD40 because it takes quite a bit to give me a headache, and it
will not explode at the slightest spark. My safety comes first.

Perhaps if you _remember_ back a little while, I mentioned that I dip stuff
in a stronger solvent (acetone, generally) to get rid of this buildup. It
is very fast acting, so I do not expose myself to it very long. It does
the job, and leaves bare metal for the new grease or oil.

Amazing...

You do really take me for some sort of moron, don't you? Even though I
have pointed out in the past that I am aware of how WD40 is to be used,
and how things are to be relubed, you just had to assume the worst and go
for the throat. Thanks a lot, thanks a whole lot.

Maybe now I can see why you complain about not being able to get a job or
why the museums don't seem to want you around. With your "never
wrong" attitude, the reason shines like a beacon in the night.

I must thank the other poster that pointed me towards the Calculator list
- I plan on trying that out. I certainly hope that the people there will
not give me this sort of "help" with my project. If I knew I was going
to run into this crap, I would not have asked in the first place.

Next topic, please...
