When I reinstalled many of the chrome parts on my car after paint, I used small amount of the window seal bead ( butyl tape )I had left over from reinstalling the back window glass. I pinch off a small amount and stretched it so there was a little to act as a seal and give adhesion. It was similar to the sticky black "stuff" that was under it prior to removal for paint.
Butyl tape is the right stuff. You can get it at any autobody supply. It comes in different diameters, but you can stretch it to suit.
