How and when during the paint process was the black applied to the tail pan or rockers? I ask because hand application during the assembly line process could have a big impact on final gloss. Too dry of an application or the gun too far from the surface could leave what was meant to be a gloss finish more of a satin or semi-gloss look. On Team Camaro the current argument is the tail panels that are survivor and glossy just got polished and waxed that way over the years... I've polished and waxed a satin finish and got a bit of a sheen but not a real gloss!!
