Nanolex Ultra Glass Sealant Review 9/10

We’ve tried a few of Nanolex’s products in the past, and we’re always bowled over by just how well they perform and the Ultra Glass Sealant was superb too…

Nanolex Ultra Glass Sealant is is designed to give you better vision through your windscreen in bad weather, by aiding removal of the water through nano technology. As with any other Nanolex product, there is a certain amount of prep work involved before you apply the Ultra Glass, but it’s not difficult and simply involves using their pre-cleaner (which has the texture of a fine car polish), then applying the Ultra Glass and leaving to cure before removal.

Although it’s a little time-comsuming to apply, it’s also fairly straight forward stuff. After waiting for a couple of hours for it to fully cure, you can then get the full effect of just how good it is. Pouring water onto the ‘screen it just glides straight off, and very little of the ol’ H2O is left behind. When driving too, anything above around 30mph and it blows off the glass easily.

We found that, as with their other glass sealants, the heavier the rain the more effectively the Ultra Glass works. When it’s lashing it down and you’re travelling at motorway speeds, we found we barely needed to use the wipers as the hydrophobic effect was so good. After a long journey, and several dozen bugs have decided to throw themselves at your windscreen in a desperate attempt to get through, removing them was far easier than with no product on the glass. You simply use warm water on a soft cloth and the muck comes right off.

Look after the product by using the correct wash techniques (don’t use windscreen wash, for example), and Nanolex say it’ll last 18 months or 30,000 kilometres! That may be the case, but as any of you car-cleaning nuts will profess, you’ll be applying it far more often than that anyway to keep it working ‘as new’.

Overall, the Nanolex Ultra Glass is a great product with very few drawbacks, and well worth using all year round. At nearly £29 for just 30ml of product, it seems pricy but consider that you only need around 6 – 8ml per application for a fully windscreen, and take into account it’s longevity and actually the initial layout will mean nothing a year down the line.

    Hi. I just noticed something strange a few days ago with my inner windshield. I don’t have a covered parking at home so I frequently use a car cover just so the car won’t dust and especially avoid the elements getting on the windshield and paint. It’s been very hot recently but the night before I used the car, it rained pretty hard. the following morning, I noticed that there was a white film buildup inside the windshield. what could have caused that. I never really had this before. I do smoke in the car but with the windows rolled down. I also have brand a new windshield and backglass which is untinted. I don’t like my car windows tinted. could the heat the built up inside the car for being parked the whole day under the sun with the car cover and the change of the temperature on the outside because of the heavy rain have caused the white film buildup on the inner windshield? however i didn’t really have a hard time cleaning it up with my glass cleaner and microfibre cloth. Thanks!

    Hi – I’ve got a question again. It’s rainy season here in the Philippines already and I noticed something new again. As I mentioned in my previous question, my screens are brand new and well maintained, at least in my perspective. I’ve really taken good measure to make it clean. Anyhow, I just noticed the when it rains, the water really beads up a lot. As compared to the screen of my dad’s car, it doesn’t bead up.

    I can’t say my screen is smeared with oil or grimes because I’ve pretty much taken cared of it thoroughly. I wash it using the 3M cleaner (spray). Alternately, when I feel it has some grimes or oil I use a product from Microtex called Stainz out which has silica compound content. Compared to my dad’s car, its windshield doesn’t bead at all and its actually not maintained at all. It’s just washed with ordinary detergent and water.

    But I don’t have any problems when I turn on the wipers. The beads are easily removed and the blades glide smoothly as long as there is enough water on the screen and there are no streaks. When the wipers are off, I can see that the bigger, heavier beads flow smoothly from the screen. When the screen is rinsed with water after washing, the water flows freely and does not separate.

    So I’m just wondering which is normal, my screen which beads or my dad’s car’s screen which doesn’t bead at all. I’m under the impression that that’s how a screen would look like when RainX is applied on it. But we don’t use for both cars.

    Looking forward to hearing from you again guys. You really are a big help! Thanks!

    Hi Chris and Matt ,

    Wow this was a quick one! Appreciate you answering right away.

    My dad’s screen is washed seldom to non at all. when it is, on good days it’s properly cleaned with detergent and on “bad” days, just water. On worse days, no cleaning at all. hehe

    And then when it rained earlier in the day, both cars were parked outside and mine beaded and my dad’s car didn’t bead at all. All the rain water just slid off like you’re rinsing it with a water hose. So I was wondering which screen was actually functioning better.

    I’m no expert so I’ll ask you like a five year old All I know is I’m excessively compulsive with my car’s cleanliness and of course its functionality at the end of the day.

    Which works better, a screen that beads or a screen that doesn’t. What are the advantages and disadvantages? Especially that both screens aren’t treated with sealants. My screen beads just like in the picture in the website, on the Nanolex Ultra review you did. Also, is the screen cleaner with silica compound ok to use?

    I stopped using the car cover just because it hits the tires which is treated with tireblack – which is oil base. I noticed that whenever removing or putting the car cover on, chances are, the undercover that touched the tires will somehow hit the screen, which will leave grimes and oil stains.

    Many thanks again Chris and Matt
