Hi all. Just got my is350 couple weeks ago and its getting hot. I'm looking for some suggestions on tint on Smoky Granite Mica. I was thinking about getting either 20 all around or 35/20. Anyone also know if there's a slight tint on factory windows and what percent that is? And if some of you SGM drivers can posts some pics of your tint and percentage that'll be awesome.
