Don't get me wrong, the CQuartz is awesome on paint & it even brings plastic back to as new condition. 1.5 years in & the coating on the paint is as I applied it, excellent performance so far. Just was expecting more from the glass, the droplets of rain seem to stick to it at speed until they get bigger & then start to move. By that time I'm struggling to see through the windscreen.
I did also apply reload on-top which I think didn't help. I'll see how it goes, will try the RainX next. 👍
