The plastic cover strips in the inside window trims shrink as the years go by. Some of the strips in the corners of my windows had started to take a shortcut.

The cover strip is available on eBay and if the colour is matched, it isn’t a difficult job to do because all that is required is to cut out a short length and replace it with a new piece. If the nearby handle lock and stay are removed, the insert can be cut and butt-jointed between the screw holes, thus giving an invisible join.

Take care not to stretch the plastic during fitting otherwise, it will relax during the following weeks and begin to pull out again.
