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)

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.

So, this product is time consuming to use. Clean clean clean your windows. When you think they are clean... clean um again! Look up youtube videos on how to properly use this product. If applied correctly, it lasts for months and repels water like a pro. This *barely* covered my 4 door sedan. I had literally none left over.

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.

Save the money and just get rainX

it's good

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.

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.

I bought the smaller bottles then applied to my vehicle 15,000 miles ago and the water still beads up. I purchased the larger bottles to refill the small bottles and give to another car enthusiast
