If that's the extent of the body work done on a 40 year old car, I think you're still way ahead of the game.
But back up a little bit... When you say "airline stripper", are you talking about the methylene chloride based paint stripper? If so, then I think you are using the wrong product there. Any of the methylene chloride based strippers are extremely aggressive, and I wouldn't want them anywhere NEAR my paint unless I was actually using it to remove the paint. I wouldn't let that stuff touch paint that I was intending to keep.
If you're trying to get adhesive residue off, I'd use WD-40.
