WWP Paint Code

WWP = White Roof, White Body, Red Side Sweeps which is the underside (below the roof trim) and I would believe the inner parts of the door jambs to make the transition to the red interior. If the car had a white interior, it would be WWW. White is one of the exterior colors that almost any interior color would work. My info comes from Galen Govier 62-65 production option code book aka Little White Books.
