I just used cheap wheel bearing grease with a brush
that's what I used, that is whats on the die, just been setting up for a while.
I hope you mean lube just the pins, instructions on my JD 32 said to never use lubricants on the forming dies groove, the tube will tend to slip backwards if used.
don't know nothing about the JD 32, I watched a friend who has bending tube for a long time he used grease on the die. mine never slipped.
