Window paint and paintbrush

Let the putty treatment according to the manufacturer's guidelines (which can take anywhere from a few days to a number of weeks, depending on the item). As soon as fully cured, paint the putty to match the remainder of the window frame, overlapping slightly onto the glass to seal the edge.
