Is there a good way to apply ammonia in this particular case? I have used a spray bottle to get ammonia all over anything that might help but still no budging. I've done it several times and let it sit for some time and still no results. Can anybody enlighten me on HOW to use ammonia to get a seatpost off?

note: I realize there have been lots of threads on this subject, but none seem to adress how to apply the ammonia
