I'm finding plastic and metal often stick. Two examples: I have some Greenworks battery tools and it's almost impossible for my wife and I to separate the pole saw sections and remove the battery (which is plastic on plastic) without a rubber hammer. The second is trying to remove new Delrin bushings from a mandrel. I have to hold it with a plyers, turn the lathe on and gently move it off. Is there a recommended lubricant for situations like this? Thank you.
