I don't mess with stripping off the back of the x-ray film. I print carbon transfer and the x-ray negatives that I develop in Pyrocat-HD for 7 minutes give me a great density range and some very nice prints so I see no need for the extra work. BTW, I got a lot of the rough sanding and some of the finish sanding done and now it is time to wet sand and polish several parts.
