Hi guys I'm a mobile window tinter by trade, and only use metalised film, it doesn't not effect receiption at all, or I wouldn't be using it, and if your worried about defects I can't tell u the legal tint is only 35% in the front two windows and u can go as dark as u want in the back, I tint most customers cars in 15% with no problem with vision, ohhh and 35% legal tint only applys to cars newer then 1992 as that when they inforced the new law for tinting, so u can tint your car as dark as u like if your car make is older then a 1992.
