No need for all those chemicals and the milennials protective clothing. Won't take any longer than your way. You can always make two opposing cuts and then the two halves of the post can be knocked out. Just takes a bit longer.
Recently used this method to remove a thompson Masterpiece
from my Ritchey frame. once the vertical cuts were made i used a thin piece of wood and knocked it in between the frame and seatpost, this split the alloy and it came out easily.
it split the alloy post
thats what i thought might happen

the frame was steel, so no issue, not sure i would have been as brave with an alloy frame.0 -
