Napa sells a product called "Door ease" it comes in a metal tube with a stick inside. sort of pushs up as you use it. It gets rid of squeeks, is cheap & lasts a long time (my tube is over 10 years old) I usuall apply once or twice a year, just push some out of the tube & rub on the weather stripping, that's all there is to it. My tube is black w/ yellow & white leters on it. It also keeps the doors for freezing shut in the winter months.
