Rust dip success stories?

Molasses Soak as per @my68barracuda
Here is a Head that I did Last winter. Turned out nice. Scrubby with hot water when done. Has been sitting as bare iron in my basement since Feb. 2022... I will try to get some more current sitting in the basement pics..

Not sure if a machined Surface finish on a crank will be acceptable. Prolly will need a good polish.
