I could just begin to make out very slight highlights on the base side. I was very surprised by this, but determined to soldier on. After about 17 minutes of this stubborness, I admitted defeat, and stopped/fixed the negative. When I turned on the lights, I was baffled to see a nearly opaque negative. Truly bullet-proof. ...
You've just dicovered why "non-solvent developers" are also called "surface developers". In this age of time and temperature it's easy to forget that all of the really basic research was done on development by inspection. And these developers really do develop the surface first, and only extreme highlights should be visible through the base.
I learned it that way, too
