Caustic Soda to melt stuck seatpost: COMPLETED!! (see p.2)

Yeah the liquid nitrogen option would be great to see - I tried the poor mans version with ice inside the alloy while heating the steel to try & shrink the post down enough but couldn't make enough of a difference to budge it. Good option though as cooling everything right down will be surely better for the paint than the 100 degree corrosion option I went for.

Someone try it and report back please!
