SOFT99Glaco Roll On Large 120ml - Rain Repellent Glass Coating for Car - Strong Hydrophobic Liquid Wiper - Ergonomic Bottle Shape and Integrated Applicator

I applied this today and followed the instructions provided.It was easy to apply and buff off, I dried the windscreen after with a microfiber cloth.It left a lovely smooth finish and left the glass sparkling.The water just beads off, great stuff.

Easy to apply, makes glass very water repellant. Make sure you follow the instructions and not leave it too long others buffing it off takes a while. Lasting four weeks easily between applications

works quite well

if you like rain repellants (and some folks just don't like this type of product at all!) then you will likely be very impressed with Glaco.the bottle design and applicator are genius - it makes it so easy to use and get good unform coverage on the screen. It dries quickly and - unlike some - it buffs off with little effort and no streaking.Also - i've now put it on 3 cars - my wife's, my daughters and my own - and it hasn't cause any wiper judder on any of these cars.Not sure on longevity - but its so easy to apply, i won't mind re-applying at regular intervals.

It's really easy to apply, certainly better than Rain-X in that respect. It works well in heavy rain when the car is moving at 20mph or more. Here I could discern no difference between it and its American rival. In light rain or drizzle it is less impressive; in much the same way as the US product falls down. In such conditions the wipers are needed and both products cause (even newish major brand) wiper blades to judder in both directions of their travel. I will continue to use it (or the American equivalent) on side windows and the rear glass but would not recommend it for front windscreen use due to the annoying judder.

This stuff is fantastic.Easy to apply and effective as hell.I've tried Rain-X and liked it, but this stuff seems to last a hell of a lot longer.I've literally done all the windows on the car with it and it's not disappointed.Well worth the money

Works great

I diligently applied this following all the instructions. Maybe I applied it too generously but even after numerous attempts have yet to buff it completely clear. I’ll update when I test it in the rain
