The smell of Ballistol is to the smell of black powder smoke as the smell of Hoppe's No. 9 is to that of smokeless. It means your gun is clean, put away, and now you can catch up on your philosophical loafing.
I met somebody once who didn't like the smell of Kroil. This after I'd just used it to unfreeze her stuck padlock. I told her she was unAmerican.
