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

Quite hard to apply and takes a while, especially to remove the residue. However, worth it when it’s finally done. Will see how long it lasts now as it’s only been a week so far.

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

WOW! The results after using this are superb. Water beads beautifully. It is easy to apply and the glass looks amazing.

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

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.
