I didnt do it myself, got a detailer to do it (with a opticoat staff advising him). That said, I did opticoat my shower glass panels, and they bead water like a champ now
I withheld from doing the glass. I did everything else though. Headlights worked out perfectly. I will get a taste of the beading action once I wash it this week!
