Gtechniq - G1 ClearVision Smart Glass - Improve Wet Weather Visibility; Durable Hydrophobic Coating; Chemically Bonds to Glass; Lasts 1 to 2 Years; More Easily Remove Contaminates (100 milliliters)

Great product

As a professional detailer, I use this coating all the time. The product is easy to apply as long as you meticulously follow directions (polish glass, alcohol wipe-down, coating application, etc.). I’ve tested this on my own vehicle and have had it last for about 6 years without having to reapply. Gtechnic hit this one out of the park. The reviewers saying this doesn’t work appear to have either a lack of experience with coating applications and/or unrealistic expectations. This sheets water once you’re up to the proper speed (around 40pmh). Yes, it’s not the slickest, but the beauty is that you don’t have to keep reapplying like other non-permanent products, plus it doesn’t cause smearing on other portions of your car. You CAN apply rain X or another topper onto this coating which will make it sheet water going as little as 15mph, but incredible results like that won’t last forever. A modest 40mph without having to use wipers and 6 years of performance blows away all other products on the market. TLDR - proper application is key and this will beat everything in longevity. Otherwise stick to something else if you want to cut corners for peak but brief performance.

Ok, so this stuff is supposed to work for 24 months or so. Took me a long time to glass polish my windshield, clay bar, clean, apply three times, wipe off residue, etc. Bottle only covered sides once, windshield three times, and not rear window (tesla M3). Less effective than rainx. Windshield has a cloudy film unless raining really hard. Does not bead up and roll off unless going 40mph or faster. Rain X rolls off at 25 mph or so. I’d rather apply a few times a year and take much less time, and have work well, for less price (Rain X). Trying to figure out how to get off my windshield now. Hate the cloudy residue.

Out of the box it seemed like the G1 (water repellent) wasn't filled to the same level as the G2 (residue remover). Given the recommendations are to cover the windshield three times with the G1, there wasn't enough liquid in the bottle to do that. I was able to get 2 times. The product seems to work OK. No idea if less than the manufacturers recommended coverage will result in less than ideal performance. Probably not going to last as long I would guess.

Product always works well but since it's so premium you don't get a whole lot of wiggle room to use it the right way. It barely had enough to cover the front and back windows. I would have loved to get all my windows on the car.

This is a high tech version of Rain-X. It’s applied like you’d wax a car. First use the included G2 to ensure a clean surface that the G1 can bind to, then buff in the G1. It takes 3 coats. An orbital polisher would be great to use at the end (I didn’t have one-it takes a lot of elbow grease to polish it in). Today, in South Florida we had very heavy rain. My wife in her car (no G1) could barely see out the windshield with her wipers on high. I didn’t even need to use my wipers as the water simply blew off the windshield. It was an incredible difference. It’s supposed to last a year, but I’ve only had it on for week. If you live in an area that receives heavy rain, this is a must. **Edited 4 months later: still sheds water extremely well, however, it does cause the windshield wipers to chatter as they wipe.

This is hands down the best water repellent I have ever used and lasts such a long time. I’m very particular with my car and always keep it very detailed, I take it to car meets, shows etc. This lasts probably close to a year, and I never need my wipers when it would downpour. Water just beads and flys off. In fact since I never used my wipers, I only just replaced the OEM wipers after 8 years. Repeat buy and highly recommend.

Decided to give this a try after seeing a couple reviews of it on YouTube and was suitably impressed. I've been using Rain-X for years to make my windows easy to scrape in the winter and always dread putting it on in the fall. So, I was looking around for something that performed roughly as well and didn't take hours to apply and buff out. This stuff just wipes on and then you use the residue remove to wipe off the haze. It becomes completely clear after that without the swirls and distortion you can get with Rain-X. As far as the beading and water sheeting at speed goes, it's good enough that I'll probably start putting it on in the spring as well as in the fall. The only small annoyance is that if the glass is dryish, it made my wiper blades squeak for the first couple of weeks but that isn't worth a star.

Seems to meet thehype

Was soll man groß sagen. Ich habe viel probiert an Versiegelungen und keine kam auch nur im Ansatz dort hin. LiquiElements bis hin zu ATU, Messe und Co Mittel. Auch teils sehr teurere Produkte von 30€+ Diese Keramik ist etwas aufwendig, aber das Ergebniss ist bombastisch. Scheibe putzen mit Scheibenreiniger. Scheibe wenn extrem alt mit Menzerna 3500 und maschine aufpolieren Scheibe fettfrei machen (isopropanol) Scheibe erhitzen (Scheibenheizung oder Scheibenlüftung auf heiß wenn draußen unter 15grad ist) Qtech Flasche 1 auf einem mitgelieferten Pad auftragen und einreiben (15-30min ablüften) Scheibenwischer erneuern oder 2x mit Flasche 1 am Blade einreiben am besten 2 Schichten mit 10min Pause Qtec Flasche 2 auf ein baumwolltuch geben und abpolieren FERTIG Extremes abperlen, keine Schlieren, Frostbeständig, Scheibenwaschwasser (alkohol) beständig, Waschstraßen beständig. WICHTIG! SAUBER ARBEITEN! Das ist eine Keramik, kein Silcon Schmierfilm.

This product worked very well for the first week. We live in a wet climate and after a week had to be going about 50mph to have the water shed off without using wipers. For the cost, wasn't worth it.

Wenn man die Flüssigkeit aufträgt, stellt man fest, dass sie sehr schnell verdunstet. Dadurch ist die Verarbeitung nicht einfach und man kann sie mit den beiliegenden Pads in der verbleibenden Zeit auch nicht über die gesamte Windschutzscheibe gleichmäßig verteilen. Wenn man "fertig" ist, bildet sich eine Schlierschicht, die man mühsam mit einem Microfasertuch zum Autowaschen wieder auf Gleichmäßigkeit polieren muss. Ist diese Arbeit fertig, passiert jedoch ein kleines Wunder. Leichtregen bildet auf dieser Oberfläche nur kleine Tropfen, die vom Fahrtwind weggeweht werden. Scheibenwischer ist dann überhaupt nicht notwendig. Das ist aber gleichzeitig auch das Hauptproblem. Der Regensensor bemerkt jedoch den Regen und schaltet den Scheibenwischer trotzdem ein. Dann aber rattert der Scheibenwischer über die Scheibe und schädigt sowohl den Gummi als auch den Motor des Scheibenwischers. Auch auf den Wischer aufgetragenes Spüli, funktioniert nur für vielleicht 5 Minuten, dann kratzt der Scheibenwischer wieder über die Scheibe. Einzige mögliche Maßnahme: Scheibenwischer auf Aus stellen und bei Bedarf (stärkerer Regen) nur händische Einmal-Betätigung des Wischers. Jetzt, nach ca. 4 Wochen ist aber auch die Leistungsfähigkeit der Flüssigkeit erschöpft und die Scheibe wird vor lauter Schlieren nicht mehr sauber. Also ich werde das Mittel kein zweites Mal kaufen und auftragen.

Good but need g4 as well
