Who is using the backlight louvers on their Bbody? I am about to install a custom made copy of the factory style and it seems keeping the window and body parts clean underneath it all may be a little tricky. I don't feel like removing it everytime I wash the car. What do other owners wbo have this optional equipment do when washing/waxing their vehicles? Thank you. P.S. I always assumed the factory louvers had hinges up top and the louver just flipped open to clean the rear window. However, the tabs they used seem to make it more of a "semi-permanent" installation.
