Griot's Garage 11033 Glass Sealant, 8 oz.

Very easy to apply in one pass. A little goes a long way. I just dripped some on and immediately buffed in with elbow grease until streaks and fog were gone. I recommend thoroughly cleaning windows with Isopropyl beforehand. Water beads off. Wipers don't skip or shutter now on rare occasion I use them. Don't need wipers above 45mph except during a heavy deluge.

I have tried nearly every glass sealant around from RainX, to Aquapel, to Fly by 30, to Optimum and I prefer Griots Glass sealant for its longevity, performance, and ease of application. The trick to making this work is a clean windshield (I mean really clean your windshield 2-3 times with a quality glass cleaner) and proper application. Here is my process and it works well and lasts 4-6 months: apply a liberal amount of Griot's sealant to a clean microfiber towel and wipe it horizontally across the windshield until the whole windshield is covered. Immediately apply a little more sealant to your towel and apply a second coat vertically to the entire windshield (you are cross hatching). Now you need to let the product dry for 5-20 minutes. Once the product is dry you need to apply a second application in the exact same manner you did the first (cross hathching). After the second application wait another 5-10 minutes and then buff off the hazed sealant with a clean microfiber cloth. If you are having problemsbuffing the sealant you can lightl dampen your towel and it will make the buffing process much easier.Follow these steps and you will have water flying off your windshield at speeds over 35 mph for the next 4-6 months on non-garaged daily drivers. Like most detailing products, 90% of the products success is based on preparation and application. Apply Griot's Glass sealant correctly and you will not be disappointed in its peforrmance and durability.

In the year 2025, I applied Griot’s Garage Glass Sealant to my windshield. Within seconds, I was no longer driving a car — I was piloting a spacecraft through Earth's atmosphere with a deflector shield set to max.Rain? Irrelevant. Water molecules make contact and immediately lose the will to stick. It’s like the glass is coated in alien tech from a galaxy where water simply isn’t allowed. Even at low speeds, droplets scatter like they just got hit with a plasma cannon. Above 40 mph? You barely need wipers — the water jumps off in terror.Application was easy — wipe on, buff off — like activating cloaking mode on a starcruiser. And it leaves your glass so slick, you half expect it to teleport bugs off the windshield before they even land.I’ve used a lot of water repellents before, but this one? This is different. This is hyperdrive-level hydrophobicity. It’s not a product — it’s a shield generator for glass.🚀 Recommended for anyone navigating wet atmospheres, planetary storms, or rainstorms at rush hour.

I followed the instructions as well as some guides; making sure to wash, dry, clay bar and clean with auto glass cleaner before applying. The week I put this on it was hot and humid, in the 80-90's with heat advisories on the news. Even then, had no issues other than my gloves turning into swamps.I opted for doing the 2nd coating the next day as suggested on the label. Wiping the product on and off wasn't all that hard, just takes a little time. It's only been a week so can't say much about longevity yet, but the water beads up and rolls off easily, rather than clinging and distorting the view.

I think a lot of people have tried this type of glass sealer / rain repellant at some point so I'll stick to a few key notes.How this differs from Rain-X is really in the failure, All products, no matter how "top of the line" they are will fail at some point; even ceramic coatings.As a auto detailer, I find this blend to be much cleaner then Rain-x. What I mean by that is when the time comes and the product fails, Griots Glass Sealant just stops working.Rain-X on the other hand, breaks down and leaves behind a greasy film. This film causes wiper blades to chatter and squeak across the glass. Also, the film creates bad night glare; I didn't get this with the Griots.Just as important to note: always clean off your wiper blades.Your wiper blades will also scrape up and collect oils, dirt. bug guts and anything else stuck to your windshield. If you clean your glass, apply this sealant and don't clean the wiper blades, you are reintroducing the same oils and trash back to your freshly coated glass.It then looks as if the glass sealant isn't doing it's job when actually it is.If you are looking for a low cost, entry level glass sealant / rain repellant Griots is a great choice.My only gripes would be the lack of durability (few weeks) and leaking bottle tops from time to time.Hope this helps.

had used rain-x for years but this seams to be an equivalent if not a bit better

Last a year or so between treatments and easy to apply.
