You may want to try soluvar. It is a non-yellowing varnish most often
used by artists. I was looking for clear medium for marking artifacts
when our source (Light Impressions) dried up. I talked with a collegue
who is the registrar at the Maryland Historical Society and she
suggested I try what they use which is soluvar. She has been using
longer than I have and said that it doesn't yellow or peel. They have
even gone so far as to experiment with printing numbers in very small
font on a laser printer (you can't do it with ink jet because the ink
runs)cutting them out and applying them between two layers of soluvar.
I've not tried this, but I have found that it does work with pigma
pens. Soluvar is available at artist supply stores. I ordered a can
from Talas, a conservation supply company and it will last me for many
years to come.
