If you want glass/nano then I highly recommend you go for the Siramik coating, there's a 3 stage coating available the final stage is Diamas (the 1st ever diamond based coating) 5yrs protection & shines like anything.
The whole 3 stage package is added everywhere, body, glass, trim, alloys & callipers.
There's only a few detailers trained by Siramik & Essex has one http://gleammachine.net/detailing-services
I had mine coated in the Siramik trio back in March & it's exceptional, my Wkly wash is down to an hr & half, also got myself a raceglaze water filter, wash car, hose off & walk away, no need to dry, no detailing spray needed as the Siramik has locked in the detail, water literally falls off the body, you can watch the rain ball up & roll off your bonnet when driving.
Sorry for the waffle but if you're thinking of glass/nano then the Siramik is the one, they're calling it the future in detailing, here's mine at the detailers
