I have not much experience with paper damaged by copper pigments
(verdigris?), but I imagine that gossamer tissue coated with Klucel
G could be an idea to use on your objects. The gossamer is so thin
that you don't need a high percentage Klucel coating. We usually
coat it with a  2% Solution in water and then it can be reactivated
it with Acetone, which evaporates in a relatively short time.

Also, Irene Brueckle and Sarah S. Wagner wrote in the Book and Paper
Group Annual 15 1996, "Remoistenable Tissue Part II--Variations on a
Theme"
<URL:http://aic.stanford.edu/conspec/bpg/annual/v15/bp15-04.html>. I
think Sarah Wagner used the coated tissue for mending, to bridge
weakened areas by moistening the tissue.
