Need some help from a rust guru!

That's a beautiful car. I remember seeing it in the Hot Rod magazine years ago. Do you realize the good paint stripper is not available any more? They took the methlyne chroride out of it and it is no longer effective. I can't find any good paint stripper anyway.
I just get the cheap stuff at Walmart or Lowes let it set a little and scrape with a blade. I was getting aircraft stripper at Auto zone the price doubled. Auto body supply house? Can't afford it.
