Warning: A customer brought in a bike with a seized seatpost from salt water damage.

Took me two full days of soaking in penetrating oil and careful heat to get it free. The whole frame was a mess of corrosion. What's your go-to method for a really stuck aluminum post in a steel frame?

My buddy had luck with a dry ice trick on a similar nightmare job.

Dry ice trick is wild. I just use a ton of heat and a big cheater bar on the wrench.

Saw a video where they used liquid nitrogen instead.
