I agree with the damage to machined surfaces not being caused by the molasses, but by the rust that was there already pitting the metal, and then once the rust was gone the pitting was evident.
I borrowed a product from my Son Don one time, called Evaporust, that he bought at Northern Tool. He used it and didn't like it, but I soaked some cowl lights in it that were really rusty and after an overnight soak they literally came out like brand new. It made the metal look like the day it was made and it left the painted parts intact. I think we might fill the cooling passages with that product and leave it overnight or so and see how that does. When Don used it I think he did a quick soak, so the secret seems to be overnight or more.
Today I called some feed stores in the area and found out what you need to buy is "liquid molasses". Two local stores sell it, but one wants to sell it in no less than 100 gallon quantities........they want $ 1.25 a gallon. The other store will sell it in quantities of 5 gallons or more, and get $ 1.49 a gallon (your container in both cases). I think what I will do is go pickup 20 gallons and one of those plastic livestock feeder tubs. Then I will soak the 350 Chevy engine block I have sitting around and see how it does on that one. If it doesn't damage that one I think it will give Dan the confidence to drop his Olds into the same mixture.
Never thought I would know so much about molasses ! :p:LOL:
