Keep in mind that these items were not painted by "The Factory". They were supplied by an independent-subsidized manufacturer, commissioned to make parts in compliance with Chrysler engineering specifications. If a "hard" paint line was evident, is is due to the mask being placed very close to the part and the paint almost running around the template/mask perimeter. It would be crazy to think that ANY specialized manufacturing firm (making cookie cutter parts) would have employees manually taping these grills prior to painting them. Such an inefficiency and waste of time would have been counterproductive to the cost of the part. There would have been no reason whatsoever to paint them this way (manually taping) since the "template" procedure was already being used for so many similarly painted parts. Even 40 years ago, technology allowed for SOME modern techniques in manufacturing processes!
