A full image on the Kirkland paper has low enough reflective 
artifacts that I don't think any glop is warranted.  A smooth sky is 
still smooth; there was no build-up of grain that way we've seen with 
the 3-MK process.  So, it looks good.

Ilford Gold FB hits a dmax of 1.72 at an ink limit of 100.  The tones 
are very neutral through the midtones. See

I'm not thrilled with the "glittery" reflections of the Ilford 
surface, but overall, this is looking like an impressive approach if 
it doesn't clog.
