Why Oh Why Do I Make The Same Mistake Over and Over and Over........
Above my avatar it says Still Learning, so here is my vent for the day.
Last year I picked up two bikes with known seat post issues. One was removed by cutting it out with a sawzall. The other, a Santana tandem stoker's seat post is still a work in progress. It will get the Kroil test soon.
During the last week in December I picked up three weathered bikes, a 1985 PH501, 1983 Trek 560, and a mid 1990's Trek MT 720. All three were field tested for moveable quills and seat posts. Nice no problems!
The following morning I had an early appointment to buy a 1982 PKN-10. It was weathered as well, the paint was good, and the chain was stiff. I didn't bother to check the quill or seat post because it was chilly out
So which bike do I attack this morning only to find that the seat post is frozen? Oy oh Oy!

I Know, I know, I know………still learning that lesson too.
I wonder what the diameter of a stick of Dynamite is? Would it be 27.2mm?

I used to pick up nearly every old tool I found. Until I discovered I had accumulated 4 of one item, none of which was worth much.
Then I became much more selective. Concentrating on quality over quantity.

I always have a can of Kroil close by. It has yet to fail me.

hah- made my day...
Between numerous 'non-bike' projects today, this SOB has gotten the better of me-
Crazy seized, corroded, no Kroil or other could break thru. Sawzall multiple slits.... no good. Walked away from it for now.

I've been there. One thing I have learned about cutting out seatposts is be very careful with the prying. It's easier to damage the seat tube with a tool prying too soon than it is to damage it by cutting too far. You can just guess how I know that.

I feel your pain, not that you could have been too surprised, with a bike left outside and with a fluted post to channel the rain...
Looks like the JPR post, a full casting so possibly an 18" adj wrench torqueing on the head just might...
A few days of kroil soak from both ends (since you'll be visiting the bb anyway), followed by some torch-warming, followed by a full cryo "soak" with a $2 block of dry ice, and maybe...
We're praying for you, brother.

I've been lucky, I guess . Out of 50 bikes or so, only had one stuck post (Trek 460) and a jammed stem ( Sports Tourer). Both came loose after a few days of soaking with oil and PB Blaster with no damage.

At one point, I was 12 out of 12. I thought I was a genius, and wondered what everyone was whining about. Then I was 12 out of 13, then 12 out of 14, and 12 out of 15. Three in a row. I've had close to 75 with either a stuck stem, stuck seat post, or both. Its part of buying major projects. Yes, I will still buy bikes with seriously stuck parts, but at a hefty discount to what major parts are worth and assume frame will be a loss. The last one of those I bought both the stem and seat post were stuck, stem came out after serious encouragement (Kroil). I had to cut the post out.

Lost a decent MB1 and a nice Nitto seatpost. Now that one hurt. Cut the remaining post in the seat tube into pies and still didn't budge. Busted out a punch and ended up with a peek a boo hole in side of the seat tube.

Why ?.... Because these frames deserve to be saved, a challenge to be met and you're the man to do it !

The PKN-10 is a hyper-lovely bike, OJ, and I think this will turn out to be a very rewarding project for you. 9 out of 10 stuck posts do. 
We don't talk about the 1 in 10.

I carry a Park 3-way hex with me. If post and stem don't move, the price goes way down. That being said. I really haven't seen any money to be made in flipping these days.

Isn't that the truth.
I buy bikes for friends that are looking and that's about it.
...and I sell the ones my kids outgrow. Which are plentiful lately.

Have you tried CRC Freeze-Off? Last winter I fought and fought with a frozen seatpost. I tried it call. Ice, propane torch, various penetrants. The *one* thing that worked was CRC Freeze-Off. I sprayed that all around and put the seat clamp between two concrete slabs. Twist. And BAM, it released.
Above my avatar it says Still Learning, so here is my vent for the day.
Last year I picked up two bikes with known seat post issues. One was removed by cutting it out with a sawzall. The other, a Santana tandem stoker's seat post is still a work in progress. It will get the Kroil test soon.

Yeah, is it just me or does the market for used bikes and parts seem really dry the past few months? I swear unloading stuff was way easier a few years ago!

Just saw that, actually. Enjoy!
....................................................................and enjoy that next next project.
On an unrelated note, did I read earlier today that you used to race cars? What type of racing?
