I had a spun bearing on the #5 journal. They welded and reground to spec. The crank was also cross drilled and grooved at that time too. The crank was given a once over prior to shipping back to me. Its hard to say how they may fix that. I looks deeper than what polishing will remove. Id give Dave a call at Marine Crankshaft to see what he thinks.
I would recommend wrapping the crank in blankets and cardboard as suggested. I used a wooden box which worked well. I have seen packages of cracks with the hanging half outside the box via the side.
