It took me over a week to get a stuck seatpost out...and it was reusable.
This past spring I had a stem that wouldn't budge on a Nishiki road bike, I cut it and soaked it with PB Blaster tapping it several times a day with no luck, then I got a deep jar & made up some OA and soaked it, took almost 3 weeks but it finally came out. I never had a stem as stuck as that before & thought using OA would speed up the process eating away at the aluminum.
I now have a very very stuck seat post in a early Stumpjumper that all the soaking & heating did nothing for, I am going to fill the seat tube with drain cleaner through the BB & see if that works. I want to save the seat post if I can or I would just try cutting it out, it is a long post that is deep in the seat tube.
