Which begs the question again, what if we wax the VDB print with 
Renaissance or similar wax? What if we coat and protect the VDB with 
a layer of colloid such as gum or gelatin? I'm testing the latter but 
it will take awhile to get answers. Problem is, in the humid South, 
even toned gelatin-silver prints are sometimes attacked by fungi and 
mold.
