## Description

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

Review: Thank you Project Farm! - Works really, kind of a pain to buff off, but is a solid product
Review: Pretty easy to apply just needs another step - 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.

## Features

- IMPROVES WET WEATHER VISIBILITY: With Gtechniq’s G5 Glass & Plexiglass Water Repellent Sealant, you can protect any glass or Plexiglass 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 as low as 30mph, and reduce 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 Plexiglass substrates such as windows, marine glass, shower doors, 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 unrivaled 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. (For best results, prep your glass using G6 Perfect Glass and an MF5 Power Glass Cloth, followed by G4 Nano Glass Polish and a medium pad, all sold on desertcart). Apply a liberal amount of G5 and work product into the glass in a circular motion covering all of the glass, and leave to cure for 10 to 15 minutes.
- 100% CUSTOMER SATISFACTION: We at Gtechniq are as passionate about the quality of our products as we are about the assistance and stellar service that we provide to each and every one of our customers.

### ⭐⭐⭐⭐ better than the competition, at the cost of more elbow grease
*by A***Z on November 10, 2025*

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
