It works Applied and buffed glass had nice sheen in the daylight (no sun). This morning heavy dew and damp air screens have all beaded droplets so it's working fine. Will give it another go in a few weeks to strengthen the protection from frost.

Excellent A1

work excellently have used this product in the past and i couldnt say a bad thing about it. add liberally to screen and leave it for 20 mins or so, then give it a good buff to remove the residue motorway driving in heavy rain requires no wipers, the water runs up the screen over your roof by the wind, only problem is, because of that it does, making the water bead up so they just join up and roll off the screen, when in fog there is not enough water so your screen tends to mist up on the outside, so then you do need wipers. it tends to last 2 - 3 months which seems enough for britains rainy times, would not recommend in summer when tring to remove the bugs from your screen your washer water will just run off.this product is much better than the duel glass cleaner spray which doesnt seem to do the repelling for very long

Don’t use on the windscreen..! Having used this many years ago, I decided to buy it for my GT86 rear and side windows, as there is no rear wiper. Previous experience has been that if you use it on the windscreen, the wipers wear it away in places and it’s just a big mess and can be very distracting. Since application my vision when wet has been 100% improved. Recommended with provisos..,,

Rain-x Recommended by a friend this product is excellent. Rain/water just runs off,I’ve used it on my windscreens and windows brilliant
