(1) Gum over Cyanotype on sized Masa paper (rough side) - (2) Pigmentthat makes gum insoluble w/o exposure?

Thanks Rayul. I tried the rough side (sized) and it works like a charm -
very clean whites. Since I started to print on the smooth size, I was
forcing that -> never thought to go back to the rough side. Both
Cyanotype and gum are sharp and nice on the rough side - when sized. I
also established a protocol in which I don't experience much
registration problems...

Actually I was planning to post the result but I ruined the print in the
last (Schmincke Ruby Red - single pigment; Quinacridone Red PV19) layer
-> the paint doesn't like to dissolve much - grrrr. Are there watercolor
paints (in tubes) that make gum insoluble without exposure? (I know this
is possible with gelatin / carbon printing...)

I have consistently printed on the rough side. I do not regret the 
I will do a sxs  to compare how multiple passes print on the 2 sides.
