Title: glyoxal yellowing - is this old news?

I just pulled out a palladium print that I had sized after printing about a month ago, but had forgotten to finish with a gumover layer. The sized area had yellowed tremendously! Has anyone had any a problem with the paper yellowing after sizing with gelatin and glyoxal? I seem to recall some discussion of this a while back, but can't find the exact thread. Does chrome alum resist yellowing better? And where do you get chrome alum? Neither B&S, Artcraft, or the Formulary carry it, at least on their web pages.

Thanks for any help.
