Was there a specific reason you wanted to stop it down to bare metal to repaint it? I’m certainly not a body tech, but anyplace that still has decent paint could be sanded with 220, cleaned and repainted. If you’re taking it to bare metal you will of course need to prim it before it’s painted anyway.

I have used a butane lighter to heat up and remove decals on a frame before using paint stripper. I have also used a Heat Gun at low temp to remove paint on a fork. I have also used a cotton ball saturated with alcohol to produce a low temp fire and remove small sections of paint on a bicycle.
I was hesitant but it worked out well. It does not get nearly hot enough to affect things such as brazing. I only put one section of the frame into the flame at a time for approximately 1 minute....watching for the paint to darken and discolor. Then I grabbed and removed it by the cold section, and scrubbed it with steel wool. The paint comes right off.

I wish I had a heat gun.

I just wonder how toxic the fumes are?

I want to try this with my stainless water bottle cage but I'm wondering how it'll come out cosmetically. I know your frame wasn't stainless but did you get a lot of bluing that didn't come off with the steel wool? Or was there anything else that was just ugly?

If you want to get the discoloration off you can wet sand it for a bit.
