Post-Factory could be one of those "references"  ( I *think* I wrote it 
up.) My students and I tested as carefully as we could -- which began 
because one student fell in love with the color of unfixed VDB and didn't 
want to "ruin" that gold color with fixer... which is what turns it to 
brown.

So we washed, but didn't fix a VDB, (or maybe several), let it dry, then 
put back under the UV light half covered with something opaque, leaving 
that for -- I don't honestly remember, anyway several hours.

There was no difference between the covered part and the uncovered part 
that we could see over a period of a couple of years. (I kept it in my VDB 
teaching kit, so saw it at yearly intervals.) I've lost track of it since 
then so there may be long-term changes I don't know about, but... anyway 
it didn't *fog* the way unfixed SG would.
