Does anyone know intensifier will work on Polaroid P/N 55? I'm trying to print out the negatives and d-max just isn't enough to keep the positives from looking pretty soft.

I used Ilford Selenium toner (IT-3) to boost negatives and the more dilute solution (1:20 vs. 1:10?) resulted more added density.
