Well, thats a graphite gun grease with a stellar reputation. (but I'm an oil guy in weapons. Thick?). Birchwood Casey "Sheath" is my fav. at the moment.. which I also wipe all train metal with. (plastic safe too. Kinda light, but doing it's job well so far; doesn't seem to collect crud, low odor on spray day, and wipes clean & "dry"(read as too thin to see) prety easily, and alcohol cleans it totally dry.
I'd have to guess that it was the kit (I'm pretty sure there was a few "bad years" for Lionel & grease)
Or it was too heavy, or just plain incompatable. At least it survived and you kinda learned a little something, eh? Lube often has a shelf life, and don't mix them if you can help it. Pick and stick to it, or be observant of it at least.
