Using a utility knife, score the paint if any on both sides of all three parting beads. Grab each parting bead on one end with nippers or locking pliers and pull it out of its dado, the flat-bottomed groove in the jamb. Move the upper sash as needed to get a good grip. If the upper sash is inoperable, pry out the beads with a chisel, taking care not to gouge the sash.
Place the sash on a padded worktable with the exterior side facing up. Clamp the sash so its meeting rail projects a few inches past the edge of the table. Remove the sash lock and set aside. Hold the router base firmly against the top edge of the meeting rail and cut a groove from left to right.
Unclamp the sash, rotate it so its bottom rail is closest to you and overhanging the table, then reclamp. Press the silicone weatherstripping, barbed edge first, into the groove routed into the bottom rail shown.
Take care not to stretch the strip as you insert it. Insert the pile weatherstripping into the meeting-rail groove.
Use a utility knife to trim the ends of each piece of weatherstripping flush with the outside edges of the sash. Lower the upper sash and measure the length of the dado in the head jamb. Mark that measurement on the shortest parting bead in the kit shown. Cut it to length. Tap the bead into its dado with the pile weatherstripping facing out. Drive tacks midway between stops and center, and then tack every inch.
