Anyone have a good plan to make the mounts on the rear glass (coupe, round black things) look better? I never had a problem on previous vettes, but this one has the two in the middle faded out to a white color.... a friend of mine has all 4 faded out... I have tried black chrome, armor all, silicone protectant, tire wet, waxing them... they look better for a while with black chrome and any of the silicone based products, but they never get all the way back to black, and it doens't last long... they look really bad with tinted windows too. If they have to be replaced, anyone know the best place? chevy kills me on prices.... thanks
