Evaporust by the barrel?

When I de-greased the windage tray I found almost no rust. I dropped it in the molasses anyway for 24 hours and it came out good and clean (don't have any before foto). I coated both the bracket (mentioned above) and the windage tray with a light application of Navel Jelly, not to remove rust, but I use it as a kind of "super-cleaner" and prep before painting. All the fotos are before applying Navel Jelly.
