I had '90 some sort of gold color and I gave to my daughter. Top and part of the hood lost it's clear coat and looked awful. Car was well less than 10 years old. At the time, I remember seeing others the same color doing this but not other colors. Of the 8 Bulls I have had/have, this was my least favorite. So I bought a '92 Sable with Essex engine, to replace this '90, really favorite car.Pretty common with certain colors and age. There's nothing you can do sans repaint it.
