Gtechniq Auto G1 ClearVision Smart Glass for Cars, Repels Water off Glass and Windscreens, Easy to Use, Lasts up to 20,000 Miles, 15ml

This is easy to apply, works similar to rainex, cant review longevity yet however its been on a month+ and its still the same as the day it. Get a very tiny amount of wiper judder in mild rain but its next to nothing, its not enough to bother me thats for sure.*Update* the product lasts about 9 months, i applied in August 2024 and come Apr/May it was starting to fade, the vehicle does about 5k a year so not high mileage. It was applied after using cerium oxide to polish the glass, clay bar then Iso alc to clean any residue so i dont believe any other type of application procedure would increase longevity.

Gtechniq G1 is hands-down the best product I've ever used on my car windows. It repels any water effortlessly of the windows and windscreen, especially whilst driving. I've used many different products over the years and Gtechniq G1 has been by far the best. The application of G1 is certainly the easiest I've known and the durability of the product since the application has been superb! Top product from a top company

In my opinion the product itself is great but there is one flaw that comes with it. There is lots of wiper juddernes after 4 ish weeks. I tried to re apply the product on the wipers the juddernes gone away for 1 day and came back. The product performs great on the highway and helps alot at night when driving in the rain. Also keeps your windscreen clean and it's easy to clean of. In conclusion I would reccomend the product but I would be aware of the wiper juddering as it can get annoying

Easy to apply to the windscreen, so far it has survived 2 weeks and 2 pressure washer cleans for its price its 100% worth it. It is extremely effective at preventing water and dust from sticking to the windscreen

so far I have purchased two lots of this awesome stuff, for my own car (A3 SPORTBACK) and wifey car (fiat 500). coverage is excellent, just use the supplied applicator pads sparingly. also allow the instructions and clean all the glass properly prior to applying. buffing off in small sections is easier. hit 50 mph and laugh at the rain blast off the screen.. 3 months on and still top performance. this goes to the top off the love list. check out gtechniq.com for instruction videos btw

I love Gtechniq but this really hasn’t lived up to the marketing.I prepped the screen exactly as per the instructions. Making sure nothing with left on. Application was easy enough, going vertically across the screen then horizontally, again applying by the book. First problem I encountered was the wiper blades juddering. I cleaned the blades, and applied some of the left over solution onto them, but it didn’t help. Over time the juddering did stop.Longevity - well I do about 4000 miles a year and it was applied about a year back and it’s non existent. No waterproofing at all. Even after 2-3 months dirt, bird droppings etc would weld its self to the screen. Other products, would easily expel dirt after a quick blast with the screen wash, but not this.I really wouldn’t bother applying again, il just go back to using rain x or another product when I next give the car its annual deep clean and protection. A shame as Gtechniq make some real quality products.

I’ve used this product on various cars over the years and has always done a good job. The longevity of the products is down to how clean your windscreen is and the temperature when applied. Generally lasts about 2 - 2.5 years before you need to reapply.A spring morning seems to be the best time to apply if you’re not lucky enough to own a garage.The box was smashed to pieces but as that is not a reflection on the product it still gets 5 stars. Amazon shame on you for poor packing.

I like it. Super effective and eliniates the blur effect even if it is raining heavily.
