Tapping the head of the recalcitrant bolt with a piece of flat steel between the bolt head and hammer can sometimes shock and partially break the rust bond.

Also a little heat might help the plus gas to penetrate a little further down the corroded threads.

Heat followed by cooling with the plus gas creates an internal suction ( Low pressure area) that draws the plus gas in.--
