Ruth-

While the strips may have worn some, the placement of the sash stops
(moldings on the inner face of the lower sash, and outer face of uper sash),
interior and exterior, may have been altered, allowing the sash to move
in/out. You may need only to adjust the sash stop positions in or out a
little bit.

I would suggest leaving only a prime coat on the outer edges of the sash
stiles, to avoid paint build-up which could cause binding of your sash.
