Getting the gum to adhere DOES take some patience, it tends to "bead up". A
couple of coats of polyurethane spray (a la Chris James) a dilute gelatin
"subbing" (a la Philippe Monnoyer - Thanks, Philippe!), and some careful
brushwork. For some reason, though, it seems to be inconsistent from
session to session. Here is Illinois we finally had a break in the humidity
and temperature the other day, and I've been mostly unsuccessful ever since.
This morning I had good luck with an emulsion made with dry pigment, but
encountered a disaster when I tried to use a tube color mix.

Negatives were lith, but diginegs work just as well.

Keith,
     So how did you adhere your gum, then, to aluminum? And, did you use
diginegs or lith or what?
