I am surprised I was never told about this because I used to work in a Diesel Shop at a Naval Shipyard for 6 years. Also the people that I worked with and been through an apprenticeship program and there were 2 machinist right in front of us in the same building.
Lots of the stuff we worked on was badly rusted.
Then just to the side of us there was a section that was part of the “Steam Gang” that worked on the stuff steam stuff for the Ships steam turbines. I mean 2 guys would spend 2-3 hours trying to remove the large Bolts with a Sludge Hammer and a Slug/Striking Wrench.. And there was 6 or more Bolts just on one side of the items they worked on. It was a daily struggle for them.
I once spoke with my Forman and said that if replacing the Bolts costs less then the labor to remove them they should cut the bolts off and buy new Bolts. But, I doubt if he ever looked in to that as it was not our shop.
So who knows if some Wax might have helped as they were there with Torches heating the stuff up. I know they used a lot of Penatrating Oil.
By the way that was Tax money going to pay those guys to beat off the Bolts.
