G5 Water Repellent Coating for Glass and Perspex 100ml - Maximum Repellency, 3 to 6 Months Durability, Beads Water, Removes Contaminants - Perfect for Car Windows, Marine Glass

Everyone who loves cars must try this cosmetics. Ease to use, very effective,

Takes a bit of effort to use properly but well worth that effort.

I bought this stuff along with some of the G4 Glass Nano Polish Gtechniq G4 Glass Nano Polish 100ml . The G4 polish preps the glass by getting rid of any residues before applying the rain-repellent coating really well. So, if you're putting this onto an older car (or even if you're not!) I would recommend using G4 polish before applying the G3 Nano Sealant Gtechniq G3 ClearVision Glass Coat . The G3 sealant itself goes on really easily. I found a folded paper kitchen towel to be the best thing. You need to apply this product as thin as you can while still getting total coverage otherwise the buffing job is going to need a lot of elbow grease! Apply the product nice and thin, allow it to dry to a haze and buff off (I use a microfibre buffing cloth) and it produces a smear-free finish fairly easily. The G3 buffs to a smearless finish a LOT easier than other rain-repellent products, such as Rain-X, that I've used before. Those products are almost like trying to get petroleum jelly off the glass, G3 is nothing like that. On the road the product performs as expected. Above 35-40mph rain just blows off the glass (and the side-windows if you do those too). There really is hardly any need to use the wipers except at very low (maneuvering) speeds. Even in heavy rain the water just beads up and runs off the screen very nicely. Another plus point is that in the summer it's easier to wash the bug splats off the screen and, in the winter, the frost doesn't stick quite so hard to the screen saving vital minutes scraping the glass each morning. Not so good, although this can be said of any rain-repellent product, is if you do use the wipers in the rain you get a momentary 'hazing' effect of the water which can degrade visibility a little but not dangerously so. Also, as product protection breaks down the wipers clear the screen unevenly making it harder to see. Therefore, if you do use these products, it's really important to top up the protection to keep the coating even. In terms of longevity, the product protection lasts reasonably well - several months I'd say. But, the more you use the wipers the shorter that time will be. So, if there's a lot of dirty spray and salt about (sadly you need washers and wipers to get rid of dirty, gritty stuff still) you'll be topping up your protection every 4-8 weeks depending on the mileage you do. Overall this is one of the best rain-repellent products out there and I would certainly buy it again. It only comes in a dinky little bottle, but you use very, very little each time you treat the glass that I'm sure one bottle will last several years.

I used this on a window that was located under a pigeon roost .. it left a coating on it that made removing the mess a great deal easier. Anything that helps with pigeon poo should get a medal. Just because I had enough left to do something else with, I put it on a tiled table that lives on the patio .. that worked well too and made it easy to clean.

Very repellent and having put it on a few window pains in additional to my original requirement, even though I did no prep and used the leftovers on my cloth, 9 months on and that window still shows the repellent properties. Repellent on glass though may not be that useful as during the daytime, water beads on the glass can make it more difficult to see out (as the beads create bright spots) compared to a normal smear, but the same window at night then becomes far clearer than the smeary version. I think my bottle will last years give how little you need!

For the price, it does the job to certain extent. Easy to apply, feels a bit waxy upon polishing.

I have use all the water repellent coating and this is the best by far can't speak highly about how it works.

Really good product providing you give a good prep try not to do in direct sunlight leave it to dry for approximately 15 minutes and buff of I used a little bit of Gtechniq window cleaner to remove it looks amazing and rain just beeds of.

Tutto ok è un buon prodotto.

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.

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.

all the other ones I've tried only start working around 41mph this starts to have the same effect around 32mph so much better HOWEVER it is approximately 300% more work to apply correctly. after application and letting it dry, getting a good buff takes sooooo much more effort and work than all the other ones I've tried. I even busted out my sander and threw on a buffing disk and it still took about 3x as long as with just a microfiber cloth on the other ones. Worth it for me but ymmv

I wanted something more powerful and long lasting, so I really feel like this is worth a few bucks more. It's thick like heavy whipping cream and lasts for over a month now, really does shed the water effortlessly.
