Way too much. (Experience). Heat all the way, I did this for a living for many years and almost never used chemical stripper on paint. I use a propane torch for most of it, caution and common sense is obviously required. You can point it all you want at paint, not so much at bare wood. Wear leather gloves and don't burn yourself.

You never want to use chemical stripper to "finish off" the job. It's toxic, messy and leaves a residue that has to be completely removed or the new paint will fail. Heat gun and really good (pull) scrapers in the end. If you do it right, there is virtually no sanding. I hate sanding. Good luck.
