Also, I will add, that the factory painted the interior colour first, so if a car was white, with a blue interior, for example, the blue painted door surfaces were done first, then masked off, and then the exterior was painted. No masking was done when the interior colour was sprayed, so a lot of the surrounding areas would be that colour before being masked off. So when sanding through the exterior white paint, one will find blue underneath. Very common to see the interior colour showing through at the door hinges.
Chrysler baked the paint, and probably baked the car after the interior colour was sprayed, then masked it, then sprayed the exterior colour, and baked it again. That is why you will see the exterior colour peeling in the jambs sometimes and showing the interior colour. The exterior colour did not adhere really well to the interior colour, because it did not get sanded prior to the exterior being sprayed, and therefore, it did not bite into the interior colour all that well because it had been cured by baking.
