How do you put this on? Do you use the same procedure that you
memtioned when sizing paper for pt/pd?

With regards to the gum vs gloy controversy, gloy is much easier to
work with. It seems to go on much easier than gum and does not require
"smoothing" with a second brush. I coat the paper using a foam brush
and uneven coats are a thing of the past. Gloy prints also seem to be
more "hardy" when they are being developed. Using gum and trying to
brush away density was a very very tricky business. Gloy prints stand
up to the brushing or water spray but you can still remove density
without ruining the print in the process. The only problem for us
Yanks is getting the stuff. Fortunately, after my trip to England I
now have a reasonable supply. I have tried some glues available in the
US and they do work to create an image but so far I have not found a
brand that I would readily substitute for gloy. Perhaps when I use up
my current gloy supply this wil force me to experiment with domestic
brands.
