Ive heard (and never used it) that its good but your windscreen is never the same again and you need to keep applying it.
I love the stuff. Drove down the m40 last night, in the dark, raining. Didn't even have to use the wipers, just runs off at speed.
I've used this most of the last decade on all my cars and for valeting other cars,people phone me to ask what i've used on their windows as water doesnt stay on them lol..
Absolutely epic stuff..Don't need wipers even in storms,,soon as water hits the windows and your moving it instantly beads off ...Fantastic stuff if used correctly !!!
clean windows properly then apply to smear,then buff off with damp kitchen roll etc and then re-apply as before...lasts for a good month and even withstands jetwashing and like i said never use wiper blades unless stationary no matter how hard the rain....

Carlack glass sealant all the way - lasts 3-6 months between applications
