Working the Fill Primer and Top Coat
PLEASE NOTE:  These webpages are under construction and their meanings incongruent until finished.
Primer is sprayed at an angle to fan rearward, then feather sanded at it's perimeter.
Each tack coat of topcoat is expanded rearward for feathering into old finish when sanded & buffed.
Light sanding with 400 / 800 / 1500 grit levels repair coat with old finish.
This takes rubbing-out the entire work area out evenly, little by little, many times.
Dark black streaks are valleys between checking in old finish.
Edge masking to block overspray mist.  Chips in old finish were masked with small balls of tape pressed in to shape.
