Cool block prep tips

You misunderstand. I was not bragging I was just stating a fact.
By the way I now use a calcium chloride electrical bath to take away rust completely in the block water passages and all. Then steam clean (not hot or cold water but steam) it and douche it with PB Blaster and bag it until I'm ready to paint it or build it.
I bet you get some great looking “stew” when you’re done. How much current & how long do you typically leave it in?
