without a doubt, agree 100% Kroil creeps far better than PB. Only downside is getting it in a pinch.
I also recommend Knock’er Loose or ZEP over PB, but again more expensive and harder to get in a pinch.
You can also thermally shock a bolt as well, but it should only be used on larger fasteners as it makes the fastener brittle. Heat the surrounding area around the fastener with acetylene, then immediately shock the fastener with non-flammable brake cleaner or “dust buster” type propellant. This 99% of the time will break the surface tension of the oxidation and allow the fastener to move.
dispose of the fastener when done.
