I would think you will have to repaint the hood.. GM had a lot of issues with the Paint process in the early to mid 90's... I'd have them match the paint and paint the hood...
I haver a 91 White Bonneville I want to paint and have found that the White paint WA8554 is $78 a gallon for the Dupont... Not too bad really.. My Medium Garnet Red Met is $178 a gallon..
The Transport I have is Dark Teal Metallic and I am afraid to ask how much that paint is
