I just got reminded of my experience with WD40 and rust. See the post from dullvinci with the pics of owners lathes "as is". I was living in Jacksonville, Florida at the time, so the humidity in the shop was pretty high, but I swear that the WD 40 made the drill chuck on my drill press rust up overnight! I had cleaned it off with a wire brush because it was starti9ng to show signs of slight rusting. Then I sprayed it down heavy with WD 40 to keep it from rusting. Big mistake! When I came back the next day it was solid brown like it had been left out in the rain for a month. There was no protection left and the surface was dry and crusty!
So I sent in a comment to the Home Shop Machinist magazine reader's forum. I wanted to warn the other readers too. They printed it in the next issue, but somebody must have complained, because a month or two later they printed a disclaimer saying that "the comments in the reader's feedback are in no way the opinion of the Home Shop Machinist magazine." or something to that effect. WD 40 is ok for loosening things up if that's all you can get, but I don't leave it on the steel parts if I'm trying to keep them from rusting. Especially not a lathe.
