Mark,

A couple of changes here:

Pigment based ink on acid free, lignin free, pH buffered, no optical 
brighteners, followed by a coating after printing.

A full coverage coating by brush, roller, silkscreen, etc. being 
better than an aerosol spray coating which does not provide 100% 
covereage.

Crane papers is the only one I know of that states they have no 
optical brighteners. They meet all the other requirements.

Piezo and MIS VM B&W inks appear to be rather equivalent. I have not 
heard anything about the Indellible. Too soon to know much. MIS has 
fade test data on their color inks. Although translating their 
numbers into real display years seems iffy. Good test results on 
Epson's pigs if you can deal with the metamerism this might be the 
best way to go.

From Robert's six week coating test what is used didn't seem to 
matter it was the fact that something is use. I have silver prints 
from the 70's with Krylon spray that seems fine after 30 years.
