I went with the FormulaOne Pinnacle also.Pinnacle full ceramic and Air 90 on the windshield on both the Mustang and the wife's Elantra.
Solarguard 28% and you don't need to spend $300 plus dollars to do it. Just my opinion. I paid $140 using a Groupon.I am thinking to install 3M tint on my mustang. Have you guys had it installed in anyone of your cars?
