Go to your local hardware store and pick up a roll of the 1/4 inch foam
insulation tape for windows. It is a polyfoam material backed with adhesive.
Spread it out on some newspaper and with some art store acrylic black paint,
dry brush som paint on. Dry brushing will allow it to remain pliable. Then get
some contact cement and apply a thin coat on the flippers and allow to dry to a
tacky feel.
Carefully press the weatherstrip onto the flippers, allow to dry.
You will need to re-align the flippers as the foam is thicker than the OEM
material.
Another.... been there... done that.
