It seems the shade I had seen on the LC is not the Llumar ATR05. I think that may have been one from the VKool line. Hehehe! My bad.
Anyhow, decided to take the plunge and get my suking tindahan to install the Llumar ATR05 on all windows except the front windshield. I'm happy that it's more black than magic, coz it's labelled as Super Black Reflective tint. It's a bit more on the brown/sepia shade from the inside, though this is very subtle. Instead of black/bluish, it's a bit brownish. I can't quite recall how 1 layer of 3M Super Black looked on the Prado, but the Llumar is pretty dark from the outside, but definitely not as dark as Super Black + Dark smoke (doh!). Still thinking of a 2nd layer for that blacked out look, but in the mean time, it's pretty dark already.
Heat rejection, not sure yet. Will post subjective findings soon.
