SOFT99Ultra Glaco 70 ml - Durable Glass Coating for Car - Japanese Hydrophobic Fusso Chemical Liquid Wiper - Water Repellent Sealant - Rain Repellent Windscreen Protection - Integrated Applicator

Must admit I was highly dubious about this, almost sure it would not work. But, even after changing wiper blades I was still getting that annoying squeek when in use so I thought it worth a try. It really works, so easy to clean the windscreen now, the water practically drains off and no more annoying squeek when the wiper blades are in use. Colour me impressed.Very easy to apply though after washing the screen I did use a clay bar. Let the screen dry properly then apply, leave for a short while then polish off, brilliant.Can't speak for the longivity, I will update here, as I have only had it on for three or four weeks so far.UPDATE AS PROMISED : Now nearing the end of February and although still OK on my car I think it needs renewing on my wifes. Her car is the one we use mostly as it's an estate and we have had an awful lot of rain since I first applied this and while the side windows are still excellent both the front and the rear screens are not claring anywhere near as well as they did. So thats nearly five months before needing replacing, can't complain at that and I'm not :-)

It’s even better than the normal version and lasts wash after wash. I won’t use anything else now

Works well for a couple of months would be even better if it lasted longer

Easy to apply ,straightforward instructions excellent result

8 months and still counting durability, designed for the aviation sector in Japan Because of the monsoon type weather aircraft have to cope with. Amazing stuff and so easy to apply and buff off.

Very easy to apply, I would suggest ensuring the glass has any previous coating removed and is meticulously cleaned this will ensure the product gives the best experience and durability. I wouldn’t apply in the colder weather as it takes 12 hours to fully cure. Once it fully cures the hydrophobic properties are amazing, if properly applied the water just sheets off.

As a motorway driver this stuff is good no need to put your wiper’s on water just beads off.. flys no more just a quick blast of the screen wash and clear as a bell really good stuff

The water repelling properties of ultra glaco are amazing but unfortunately cause extremely bad wiper judder, so bad so that I had to remove the coating completely.I tried putting ultra glaco on the actual wiper blades as I read this could help but it actually made it worse.I still use ultra glaco on the side windows aswell as the rear as I rarely actually use the rear wiper anyway and glaco does a great job for those but very dissapointed that it can't be used on the front screen due to the noise and judder it causes,This should be more clearly advertised as being possible as its quite an expensive product that doesn't last as long as advertised so for it to cause this issue makes it not worth the price for just the side and rear glass,
