On the inside of the heater control section of the dash they used a whit paint over the blue area of the slide knob. I decided to mess around and paint the entire thing in whiteout except the display area and the red area. Kind of like a light resonation chamber. It turned out nicely with LEDs. It gave a good smoothing effect. The only problem is whiteout starts to crack in large ammounts like that, (it's ok, it comes off with goo gone). I'd like to keep the white 'resonation chamber'. Any idea what type of paint that is under the blue are on the center clear portion?
