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 coating.
