Not only the texture (which is understandable, because they are different kinds of metal), but the paint color on the taillight centers often didn't match the decklid panel. Usually, the taillight centers appear darker, more like the later "dark argent" paint. Obviously, to look good, they should match, but it seems like the parts suppliers screwed this up back in the day. To me, it looks better when there is a little more contrast between the polished edges and the textured centers; that is, when the argent paint is darker. I am tempted to add a little black when I refresh my tail panel.
