92184 Premium Glass Cleaner with Rain Repellent for Exterior Automotive Glass and Windshields to Shield Against Rain, Snow, and Sleet, 22 Fl Oz, Pack of 1

I bought this product hoping that it would help keep the rear screen almost clear of rain but after a couple of attempts (following the instructions) I've not noticed any difference the rain does not run off any better after its been applied, it does clean the glass easily but that's all I can say. I'll try it again to see if there is any improvement but I'm not expecting any.

Works well, but does require quite a bit of graft to get a properly clear finish. Rain repellent is only just OK, Rain X on its own is better, however this product does not 'mist' as much as Rain X does when you have your wipers on.One tip - don't be tempted to use a microfibre cloth to buff you glass clean - for some reason the Invisible Glass seems to attract the fibres and the net result is that you end up with millions of tiny fibres stuck to the glass, most of which you don't see until it goes dark and you have headlights coming in the opposite direction.Oh, and don't use too much - a little goes a long way!

I first saw this when i saw beading effects on one of my mates car. Even in heavy rain not once did he have to put the wipers on. So i decide to try it myself expecting the process to be hard. But all i did was spray it on, leave it for about 15 mins and wipe it off. Cleaned my windshield and in rain the water just slides off.

It does repel rain for a brief while, but despite carefully following the instructions I won't be using this again after 3 attempts. Soon after the initial "Wow, that's loads better" feeling of the first few showers, the wipers smear as much or more than before, simply with a pattern of rather more gathered small droplets instead of smears, which is equally difficult to see through. Do you want to replace this product every 3rd rain shower? Me neither.

I use this religiously as part of my car detailing routine. I recommend using with a waffle cloth so there is no lint left on the windows. You’ll soon notice when driving in the rain that wipers are no longer required - fantastic durability with longevity of approx. 1/2 months maximum though I recommend a top up every couple of weeks in harsher conditions.
