Gtechniq G5 Windshield Water Repellent Coating on Glass & Perspex 3.4 fl oz

Easy to apply, works as well as Rain X however lasts a lot longer. Saw a review and decided to try it. For the price it's a no brainer. I saw comments that it was difficult to remove however I did mine on a cloudy day with temps in the low 60s. I used a new microfiber cloth from Costco to remove and had no issues. Follow the instructions to shake well and use a small amount and wait the 15 minutes before buffing.

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.

Really beads up on my new shower tile but the resin leaves blotches on the tile if you leave it on even a minute longer than needed before buffing off. The key seems to be doing a couple square feet at a time, buffing clear with a microfiber cloth. The blotches come off with another application. Small bottle but, it goes a long way!

Been using this product for some time but still a good product for me

Sorely disappointed with this product’s performance. I cleaned and buffed a large glass surface and applied this per the manufacturers recommendations. I had better performance from much cheaper products I was really hoping for a better result on perfectly vertical glass. Water does not bead or shed very well.

This stuff really repels the water off the windshield. It's reasonably easy to apply, and holds up well over time. Water just keeps beading. Be sure to follow the instructions, and don't worry about the smell- it goes away quickly.

Kind of works. Does not make the water bead and roll off of the windshield.

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.

He probado este producto en dos ocasiones. La primera lo puse sin un prep y sin algún producto que quitara el poco sarro que existía. Duro una semana y un par de días. Lo estoy usando en época de lluvias. La segunda ocasión prepare los cristales perfectamente y lo aplique con pads y suedes. Fue mucho mejor la aplicación. El efecto hidrofobico fue excelente la primera semana, la segunda semana disminuyo considerablemente, me parece que este producto no dura mas de unas 3 semanas. Por el tiempo de aplicación considero que no vale la pena en absoluto. Insisto los primero 3 días funcionó bastante bien en carretera, despues de la primera semana se ha ido degradando considerablemente. Finalmente, el producto inicia su efectividad a partir de 80-90 km/h, arriba de 100 es muy buena, pero antes de 80 es mínimo el efecto. Lo aplique tambien en un casco de moto, me parece que funcionará bien, al menos por un tiempo. No lo recomendaría.

Tutto ok è un buon prodotto.

Almost doesn't work and leave white coating over the widow that affects vision. Aquapel still is the best for me.

I've never used this type of product before, despite having thought about it for many years. Why did I waste those years! This stuff is amazing, the water just beads and runs away under the air pressure of moving forward, most effective over 30mph. Been out today in the rain and only flick wiped the windscreen twice, no need for contanst wiping. Much to my delight, when arriving at my destination, the windscreen was as clean as when I set off, even with having been past lorries throwing up a lot of dirty spray. As with most things, preparation is everything, prep'd windscreen with glass cleaner, then used the G4, then the G5, as per the instructions. results are stunning, go buy some!

Great product and easy to use
