Griot’s Garage Glass Sealant Coating for Cars, Trucks, SUVs, and More, for Water Spots, 11033, 8oz

Applied in three coats on all glass. Amazing product which virtually eliminates the need for wipers in rain - because water sheets off so well. Applied to my three German vehicles. My new goto for glass

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.

Works great, no streaking or hazing at all. This product does what Rain X pretends to do.

Love this stuff

First off, impressed with this. I put it on close to 2 months ago and it still going fairly strong. It's definitely less effective than initial application, obviously, but it's clearly still working. So that's promising. I live in upstate NY and didn't see much rain, but have seen dramatic temperature changes. Which brings me to my reasoning for 4 stars... It doesn't prevent ice buildup as it states it does. Not at all. I thought that'd be nice for over winter application, but it doesn't seem like it will help much with that. It also does not prevent fogging, but it never claimed to do that anyway. Overall, I'd probably buy again. Application took about 15 minutes, so it's nice and easy. I applied it to my rear view camera, rear windshield, front windshield, and side mirrors. Only noticeable difference was on the front and rear windshields, occasionally noticing a difference after several minutes of driving with the rest.
