20% is correct. However, to get a perfect match (which probably won't happen) you'll need to go and get it professionaly done. That quote for the front two windows may be true for cali, but you boyz iz gettin ripped! :reddevil: I see your in Baton Rouge, and I am sure its a lot cheaper than that here. When I had a sub contractor doing tint at my place, front two were usually $75 and that was with me gettin 30% of the take.
I personally have the factory 20% rear with another 20% sheet over it, effectively about 5%, and 20% on the front. You can have as dark as you want from the rear door back, and the front window at 20% in Georgia
