SOFT99 Ultra Glaco 70 ml - Durable Glass Coating for Car - Japanese Hydrophobic Fusso Chemical Liquid Wiper - Water Repellent Sealant - Rain Repellent Windscreen Protection - Integrated Applicator

I've been using this for years and I've not found a product that beats it for performance and ease of use. Lasts for at least 10-12 months so great value for money and longevity, application is simple and smear free, helps to clear spray and heavy rain alike

Fantastic product and easy to apply/use

Easy to apply and buff once cured, leaves windscreen really clean, all door windows supper clean and protected.

Lasts a lot longer than rain x and produced 0 wiper judder. 1 bottle felt like it would do my car twice, so it’s a lot more expensive but you only have to do it 2 or 3 times a year. For context, rain x used hardly any product but only lasts a week or 2.

Excellent product clears water from the glass very fast. Very easy to apply and buff, would advise to use a damp micro fibre to buff.

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

It’s advertised as no more spots on your window or mirrors, it just doesn’t work . It still left water marks as always . Waste of money
