I wonder if the whipping cream works because of some emulsifier in it.
Whipping cream usually has a bunch of stuff in it to thicken it and to act
as an emulsifier. I wonder if the emulsifier would be more effective if
added directly to the emulsion.
I also wonder about coating using the technique suggested for wet plates,
that is pouring at one corner and allowing the emulsion to flow over the
surface the excess draining from the opposite corner.
