Apply a thin layer of glazing compound in the primed grooves. Press the glass lightly to bed it. Press in new glazing points every 10 inches with the tip of a putty knife. (Note: Do not put any downward pressure on the glazing points when inserting, or they could break the glass.)

Apply glazing compound. Move the tube tip along the edge of the glass while steadily squeezing the trigger. Smooth the glazing with a wet finger or cloth.
