Moreno,

I used Varathane Diamond Finish Semi-Gloss and it was very nice and clear
when I applied it. My favorite in fact for looks and ease of application,
especially on Museo. Now some 14 months later the prints look like I had
used them to paper train the puppies.<G>

Yellowing may not be an issue depending upon the look you want. I would bet
that over the years your shellac will turn a bit orange which might be
interesting.

Someone tried some hand rubbed waxing and liked it as I recall. The was a
whole bunch of posts under the thread Alternate Coatings or Alt Coatings on
the Piezo list in the Spring of '01 by Bob Tyson who tried a whole bunch of
stuff from the hardware store.

You might just want to give some of the classic oil painting varnishes a try
too. Golden also makes an oil base version of their UV resistant art varnish
but I found the 3+ days of drying made things difficult without a drying
rack.
