You could allways racer tape (Duct Tape) all the journals with a double layer of tape before blasting the counterweights. If the rust is deep on the journals, the crank should be remachined. If the rust has really pitted the journals i would probably stay away from it and find another crank. I have done this and we allways use glass beads in our blaster, # 8 grade i believe.
Just my .25 worth.
