Assembly Lube Protection Duration

How long does an assembly lube last during engine assembly? For example, if you apply assembly lube to the bearing journals and leave the engine sit in a partly assembled state, is there a time after which you need to disassemble and re-apply assembly lube before continuing?

I would speculate that it will last years. But I've never tested it. Can you turn the engine over by hand easily (assuming no cam assembly is installed?) If so, I would not worry about it, just build oil pressure before the initial startup as normal.
