I got my windows tinted and asked them to match it to the second row windows. They installed a 20% and I can't tell the difference. However, in Alabama 35% on the front windows is all that is legal. It seems like my rear window is a lot darker though. Ill have to go look to verify.
I wanted the 6" strip across the front window also, but the little black dots around the electronics was going to force them to split it into two pieces, one on either side of the dots. Tint doesn't stick well to that black material.
You want to talk about dark tint that you can't see out of....my 01 s-10 has 5% black on top of 5% mirror w/ a checkered flag pattern. I've had 8 tickets. The tint meter read .03.
