GF's bike has alum seat post seized up in frame (also alum).
Any tips on how to get this loose?

Stuck seat post

Start by taking the clamp off so you have easy access, then proceed to spray PB blaster into the non-existent space between where the post slides into the frame. Let it sit there and try to do it's work and repeat a few times throughout the day. Try a little bit of twisting at the end of the day and see if it worked its' magic. If not, grab a pipe wrench or channel locks and grab the post just above the collar and put some force into a slight twist back and forth. If none of this works, there are more drastic options like adding heat or cutting the seatpost off and then cutting a slit into it from the inside, but try to avoid those.

Thanks. What is PB blaster?
It's a penetrating oil. You can also try WD40 or Liquid Wrench as well, just tape a towel or something around the frame's seat tube so it doesn't drip down. Not sure if any of them will damage your paint, but you definitely don't want oils on your brakes, etc.

It's a type of penetrating oil like Liquid Wrench. Also, if you have the frame torn down, you can turn the frame upside down, spray some through the bottom bracket opening into the seat tube. Clamp the seat post in a vice and use the frame as your leverage to loosen frame from seat post.
Brilliant!

The Thompson almost looks like it was made to clamp in a 1/2" black pipe like that.
