Llumar recently replaced the AT line with ATC which is their "performance dyed" non-metallic tint. $179 was my price at Select Sound in the land of cows (South Dakota). It's a "color stable" dye and has the all too common lifetime warranty. Llumar has a lower end Jet Dyed film that only carries a 3yr warranty so I have some faith that the ATC line won't purple out. High quality dyed tints from Llumar and others have apparently improved vastly from what I've read on the pro tinters forums. ATR is probably Llumar's most popular tint, but I didn't want to introduce even the slightlest amount of RF interference since ATR is metallic-based (FM, Navi, and 2way remote start soon). Ceramic would be nice, but I couldn't justify it at $329.
Before the install, I removed the door pin screw (it's used as a ground) in order to disable the automatic window drop and rise function when opening doors. Front windows are 35% for legal reasons and rears are 15% which is close to the 20% legal limit for SD (20% isn't available in ATC). Pictures were taken at my dad's hanger and his ultralight is gracing a few of the shots:
