Sounds to me like the auto body shop did the paint job backwards! Best tip I ever received (and worked great) is to paint the machine letters or embossing the color desired, put it on thick over the letters and embossing. Let this dry and cure. Now paint your entire cooler the color desired, painting over the color you just applied to your letters or embossing. Again let this completely cure. After everything has cured, wet sand your embossing until you have your desired results, buff and wax and you have your paint scheme!
