The factory tinted windows have always been adequate for my gal's 2005 Expedition, but after having my van done with ceramic, I couldn't wait to have some put on the Ex.
I had the van done with Llumar Ceramic 80% rear and 20% front doors....decent pricing, lifetime guarantee, etc., etc...........but that is not what I got excited about.
Llumar has a special (ceramic) product called " Air 80". It is especially designed for windshields. I know......I know.....you shouldn't tint windshields, but with all the surface area of a van windshield, there is a ton of heat that pours in on even a cloudy day. I was skeptical but it looked harmless enough color-wise, plus it's only $125.00 extra.....AND comes with a Lifetime Guarantee. May 2017 pricing.
Gentlemen, let me tell you this has to be the single greatest upgrade you can do for your vehicle. I've driven west into the sun on the Interstate just to enjoy just how much heat it blocks from getting into the van. Long story short........I did the Ex a few weeks later.
The wife had a bit of a problem with the dark 10" or so tint strip at the top as I did at first (also included), but we both have learned to love it. Looking directly into the sun without having to reach for your visor is a small perk often enjoyed at a quick stop or a take out line.
I saw it at first, but quite honestly, there is no way you can tell it is installed. I do not notice any loss of vision or clarity at night, which had me a tad worried with the 80/20 specs. I love it......but you already knew that, huh?
