who did your pinnacle 80? As far as I was aware, pinnacle was only made up to 50%, and Flying Window Tinters in Longwood uses Llumar Air Blue 80. I had considered doing the 50% on the windshield, but was afraid it would be too dark at night.I have formula one pinnacle 80 on mine...no clarity issues whatsoever. On my old stang I had 80 Huper Optik on the windshield with no issues. If it were me, I would stay with the HO so you're consistent all the way around...if it matters.
This is what I am thinking as well, but on the odd chance there is a pinnacle 80...I would guess you have the Llumar Air 80. Formula One Pinnacle is a part of the Llumar brand and they probably miscommunicated it to you. Definitely verify with them and check your tint paperwork / warranty registration records which will specify the exact tint used.
