Hi All,<br /><br />I have an unmixed gallon kit of Diafine for processing a lot of rolls, just got new plastic gallon photo bottles to store it this last weekend..&nbsp; I need the gallon capacity for very large tanks.<br /><br />Recently I have read a few references to Diafine suddenly dying after a while.&nbsp; Anybody care to comment on that?&nbsp; Back in the seventies, I had a quart I used for at least a year before I threw it out &nbsp; I have read if you take care of it, it will last until it completely dries up. What does everybody think?&nbsp;
