On the other hand, it might be unnecessary to use the tube if the rust inhibitor readily spreads over metal surfaces by itself (similarly to, say, kerosene or WD-40).

I will try to grab you a pic from the inside later today or tomorrow. Pretty wet out there today. I like the flexible tube as it would cover all areas, but, yes, if you dumped tons of stuff in there, it should fill up a bit and soak everything. I guess you just never know how much debris/dirt is in there, so you want enough oil to thoroughly soak through that to the metal.
