Thats Chrysler! Ill bet maybe yours had it but in a lighter amount and deteriorated. My car is one owner. The older gentleman hit the the left front fender so he parked it in garage in 2012 but he always kept it in garage and he had maintenance receipts in car as well as IBM card and I found a build sheet. So maybe mine were protected? Also depnds on the plant. My dads 69 swinger had a factory turquoise 340 hi po when it says they should be orange and another person has a factory red 340, a 68 color. But thats what make Mopar so cool and different.
