It's definitely very good, that I can't deny. However, I have seen more hydrophobic products. It's durability is unmatched.
Not as Good as Expected
October 25, 2020
Very expensive. Expected the water to roll off my windshield. After a diligent application I'm disappointed. It's god but not great.
ProsWorks good but not great.
ConsExpensive. Expected more.

Works well and medium rainfalls and high speed. Not so great at low speed or heavy rain. Then you have to use your wipers so it doesn't last too long. It had worn off after a few months and it's expensive. I'd rather just put a coat of cheap wax on after each wash. Better results for less money.
Best I've Used
November 1, 2019
I always used Rain-X, which is a good product, but I always had an issue buffing it off to a streak free shine. Stoner's Repel was way easier to use, but didn't have long lasting effects. This stuff lasts ages! I did do a full decon and cut of the glass (CarPro CeriGlass DA Polisher and Glass pads), cleaned it with IPA and then appied it. I have used it on a '78 Holden Commodore, '12 Chrysler 300, '14 VW Golf, '18 VW Passat, '19 Kia Picanto and '08 Hyundai Getz and the results are always the same. Brilliant. The oldest application is now 6 months, and is still going strong. I highly recommend this product, you will definitely not regret it.
ProsEasy to use and lond lasting
ConsNot enough residue remover provided, but I dilute whats given with 500ml IPA in a spray bottle and it works fantasti.
BEST water repellant

I've used many wind shield treatments and this product is the best! 14 months on my daily driver and it works like I,put it on yesterday. I bought the 100ml bottle so I could do my other 2 vehicles. It IS worth the cost and simple to apply. Highly recommend this product.
ConsTakes awhile to apply but well worth the time

Does it's job

For the price and the effort involved with this product, I will continue to use G5 as it's not as difficult to apply and I really don't see the longevity from the G1.
ConsHard to work with Tough to remove Takes a lot of time to get it right H2o evacuation happens at around 40mph
This product LASTS!

I have used this on all my cars, 3, and my parents van. This has been on my parents van for 3 years now with NO touch ups and still has good repellency. They drive about 15K miles annually. It's all about the prep and layering the product. After using Rain-x windshield prep/polish I rinsed off the residue and wiped down the glass with 50/50 Isopropyl alcohol before applying the coating. It does require a good bit of elbow grease but it's well worth the effort. If you want something that works great and is easy to apply use the G5!
ConsRequires quite a bit of elbow grease.
G1 beats RainX
