Cleaning up an axel housing

I did mine with a wire wheel and then sprayed it with converter, encapsulator, then chassis black. It would have been a lot easier with a sandblaster. Especially if you have pitting. You can fix the pitting if you coat the parts with a layer of Metel-to-metal body filler and sand it down after sandbalsting, but not if you wire wheel, you will have to use rust converter if you do that.
