I have a 1962 Pontiac tempest LeMans. It has been poorly refinished a while ago. The color code in the engine ID plate says "CC". I have checked on internet and and "C" (not double C" ) means Cameo Ivory which makes sense if you look at my avatar. But I can find trace of dark metallic blue UNDER the Ivory color which makes makes me wonder that the ivory is not the original. So I am pretty confused and because I want to restore it to original color I don't know what to do. Any expert out there? I appreciate your time. Eloy
