La-Z-Link you can see the gray between the fog and signal is the same grey that is on the accent stripe and around the rear view mirrors. As far as where to paint, it is basically a pilliar between the fog light hole and the signal. It should become obvious upon inspection.
Props to you for spending the time and money to paint your 99 jspec fascia properly. It is a shame more people don't.
