Sounds like the very same stuff.
Mt board was small, hence I didn't have a large area to smooth. The roller may be needed on a larger board o get the smoothing done before the gum becomes tacky.

Would that stuff happen to take the form of a brown, sticky liquid when in
the bottle? I've used it before. It's not as popular as PVA, but a lot of
places still sell it around here.
I suspect rolling it on with a rubber roller would get the coating pretty
flat. You have one roller on the top that's half-immersed in the gum, the
other half touches the second rubber roller (transfer roller) and transfers
the gum onto it. The transfer roller transfers the gum to the paper.
In theory you should be able to get a fairly even layer on the page. I think
rubber rollers are used for screen-printing...
Later.
