Yeah, well it was the only thing that came to mind on my drive to work. I'll put something a little longer lasting on it when I get home. The cylinders were fairly oily when I put my bare hands on them to feel things, but after that coolant went into them I was a wee bit worried about rust. I just don't want to do what I did to my first 460 when I stripped that thing down 15 or so years ago. I took it half apart out on the street in front of my dad's house and let it sit through winter when I gave up on whatever it was I was trying to accomplish. It looked like scrap when I went to mess with it months later. All the cylinders were coated in nice thick rust. Fortunately (or unfortunately) it was easily taken care of with a .030 overbore. 🤷♂️Water Displacement formula #40 actually (I am a walking tome of useless knowledge). Buy it in 1 gallon cans - great lubricant for machining aluminum and displacing water, but it's not going to do much for what you are asking of it.
Boshield T-9 would be my go to but it's not easy to find. Amazon and Woodcraft will both have it. Hell CLP from the gun aisle at Wallyworld or slathering on any old grease you have laying around would be better than a penetrating oil like WD40.
You need something that's going to stick until the engine's striped for rebuilding.
