Gtechniq G5 Water Repellent Coating for Glass and Perspex 100ml - 3 to 6 Months, Beads Water for Car Windows, Marine Glass

The hydrophobic properties of this is really good. I would say its equal to Rain-x when its brand new. Expect Rain-x doesnt last for nearly as long. Ive done several washes on my vehicle as well as using wipe fluid every once in a while and it is still working really well now since about 4 months ago. Rain-x you start to notice its weakening significantly in just a couple weeks. The main downside ive noticed is after applying it takes a LOT of elbow grease to fully buff it in. I kept going and going and could still see a haze, took about 15 minutes and a sore shoulder to get it done. Maybe I needed to apply it thinner, but either way Im getting a polishing wheel attachment for my drill for next time.

This stuff is a very good product. I about a month in and so far it works very well. I have an issue with my new peterbilt 579 where a cyclone develops on the drivers side window when its raining pretty heavy so it makes it hard to see the mirror which in my line of work is super dangerous. So far though it’s working wonders. Is this as easy to put on as RainX….id say it’s about the same. It’s like applying a wax to your windows where as rainX is either a spray or the wipes. I will say the instructions on this though need a bit of work because they say to avoid water for 2 hrs after application but they should add an extra step like RainX does….like applying water to your microfiber cloth then going over the window again AFTER the 2 hours to wipe off the haze left behind. I would say follow the instructions but do this extra step afterwards. I also applied this stuff to my moms Subaru and shes been pretty happy with is especially since rain in the Midwest is pretty much all over the map.

Great product that does exactly as it says. The bugs even slide off the windshield.

Does what it says.......... make sure to follow the instructions and please apply to clean glass.

Works great

Only works ok. Does not live up to the hype.

Does not work as good as rain X and didn’t last as long

Terrible for night driving. Left a film that made every light source look like you have a terrible astigmatism.
