Gtechniq is well known in the UK and has just started entering the North American market. Their new US HQ is in Wilton CT and one of the nearby detailing shops has been running a special on their products. The results were fantastic and not really conveyed by photos. There is a depth and shimmer to my silver Model S that was not there previously. It is almost like the car was dipped in in the finest crystal. I have no way of comparing it to Opticoat, Glare or Crystal QZ (sorry Artsi :redface, but I am thrilled with the results. The windshield so far is behaving like a having a new coating of Rain-X with no grab from the whiper blades. https://www.facebook.com/media/set/?set=a.10151334464316199.1073741839.19856941198&type=1
