So far the results are better with this setup, roughly 8 hours of this, 10 minutes of wire brushing (with a hand brush, not drill) and it looks brand new! I don't think they even need to be turned! Not sure how long the second one will take, I think my sacrificial metal (nails and push rods) are about spent. The first rotor ran about 5 amps and the second one is running around 2 so it'll take a bit longer. I'm in no hurry though. Pics:
Rotor Chili anyone?

No difference:
