Use impact driver (air) on low low pressure so as to tap tap tap on the bolt over and over, spray down with liquid wrench or equiv and gradually increase air pressure. Rubber hammer on surrounding area if you can, lightly, while doing this. Do you have 4 hands? Don't forget to put the driver in reverse!!!!
