Just happened to notice light (and a narrow, cold breeze) coming through a small crack in one panel of my 50-60 yr old front door.
A) quick remedy? Masking tape? Duct tape?
B) recommended caulk or semi-permanent solution? This is a door with about 1000 layers of paint on it. And *extremely* limited budget for repair. I.e., no "get a new door."
