RE: VDB
Yes Scott, it has to be fixed in a dilute fixer (5%) just like normal VDB. I fix my VDBs and I find that unless very strict processing is followed for the VDB within a short time I have a degraded image either from the iron or the silver left in the print. So a fix (and you call it hypo, I think you are not referring to hypoclear are you?) is a given for me, but if others don't do it, take their word for it as well--your call.
