I've also switched to a PVAc based transparent wood glue as sizing. I dilute
it 1+4, gives enough protection for 4-5 layers w/o the sheen of full
strenght. (I can't say I like the sheen; it takes something from the gum
prints...) Not that I think gelatin sizing is too much a PITA but it's
surely much more practical.

OTOH, I'm a little bit nervous about the longterm effects of the sizing to
the paper and its longevity; because I don't know for sure. Any thoughts?

Regards,
Loris.

P.S. for Turkey based gum printers: It's "Filli Boya"s (Caparol's local
brand name) "Fil-fix Şeffaf" transparent wood glue. (You definitely want the
"Şeffaf" version of the glue, there are many Fil-fix products!)

I really like the PVA for gum prints...the ease of use and the slight sheen
are definitely pluses for me. I use it full strength on Canson Montval 140
