When someone brought up gesso last time I tried it, but it was too
gritty and I didn't like it.

What I use instead is Roam and Haas Rhoplex AC-35 (methacrylate and
poly(vinyl alcohol-co-vinyl acetate) made as a plain medium for
acrylic paints). It makes the sizing layer more durable but too much
of this in relation to gelatin would make even brush coating of the
emulsion much more difficult. (Coating rods, etc. should be fine.) But
when used in a small quantity it works very nicely with all methods of
