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! Review: Best water repellent for glass windows - Great product and easy to use ## Features - Causes severe skin burns and eye damage. - Flammable liquid and vapour. - Harmful to aquatic life with long lasting effects. - IMPROVES WET WEATHER VISIBILITY: With Gtechniq’s G5 Glass & Persepex Water Repellent Sealant, you can protect any glass or Perspex surface and transform it instantly into a durable, hydrophobic surface that improves visibility in the rain. With improved beading, the rain will roll off any G5-treated glass surface at speeds at as low as 30mph, and reduces smears and marks from day to day use, leaving a virtually spotless surface - PERFECT FOR COMPOSITE GLASS: Since it improves visibility through any glass that is treated with G5 Repellent Coating, G5 is perfect for your car’s windows during any wet weather. It’s a perfect all-rounder for glass and perspex substrates such as, windows, marine glass, shower screens, headlight lenses and so on. It’s not as durable as Gtechniq’s G1 Clear Vision Smart Glass, also available on desertcart, which is designed solely for glass surfaces - STRONG CHEMICAL BOND: Unlike regular rain repellent coatings that adhere to the surface of the glass using relatively weak physical bonds, G5 uses a strong chemical bond which gives G5 unrivalled durability. Any glass coated in G5 will stay cleaner for longer and any contaminants such as bugs, bird droppings and ice will be easier to remove. With one application, the beading effect will last up to 3 to 6 months of durability - EASY TO USE: With Gtechniq’s G5 Water Repellent Coating, you don’t need to be an expert to apply it. Shake well before applying, and ensure that your surface is dry and free from residue.

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! ### ⭐⭐⭐⭐⭐ Best water repellent for glass windows *by A***R on 10 May 2026* Great product and easy to use ### ⭐⭐⭐⭐ Great stuff and easier to buff off than other products.. *by K***N on 19 December 2011* 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. ## Frequently Bought Together - Gtechniq G5 Water Repellent Coating for Glass and Perspex 100ml - 3 to 6 Months, Beads Water for Car Windows, Marine Glass - USANOOKS Microfiber Cleaning Cloth Grey - 12 Pcs (12.5"x12.5") - High Performance - 1200 Washes, Ultra Absorbent Microfiber Towel Weave Grime & Liquid for Streak-Free Mirror Shine - Car Washing Cloth - Invisible Glass 91164-2PK 19-Ounce Foam Cleaner for Auto and Home for a Streak-Free Shine, Deep Cleaning Foaming Action, Safe for Tinted and Non-Tinted Windows, Ammonia Free, Pack of 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/49189185-w5-water-repellent](https://www.desertcart.be/products/49189185-w5-water-repellent) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-24*
