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

Seems to do as claimed. Will have to see for how long

Ok, so a major edit here - this stuff is kind of alright, except you need to put in mega effort in the “buffing off stage - here was my original review: -I didn’t get juddering wipers, but did get smearing - and a visible line left where my left hand wiper ended its travel - pretty much in front of my face. This was despite putting in lots of effort in the “buffing off with a damp microfibre cloth” stage. The results of this looked perfect, but not so in the rain. I applied the treatment on Saturday, gave it a second buffing on Monday. Now it’s Wednesday and I’ve used acetone and kitchen roll to try and remove it. Careful if you do this - acetone would probably melt your paintwork! I then followed the acetone with GTechna glass cleaner - seems to have got it off now.Edit - not so sure about the acetone, still getting weird marks on my screen. Think this is because it’s on the wipers - I may have to buy new wipers.I then had another go at cleaning it off, (wipers as well, but did not replace them) and now, miraculously, it seems to be working as it should! Water beading and running off, no wiper judder, no smearing..But what a battle!

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.

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

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
