So what is the correct way too apply it then? I’ve followed the instruction exactly as they written are on the bottle and its made no difference whatsoever.
Just as it says in the instructions.
Clean windscreen (make sure it’s really clean!)
With a decent microfiber cloth, apply in circles, then leave for a few minutes
Buff off with a second cloth.
Spray some water over and use a paper towel to further remove any haze.
Make sure it’s buffed off properly or else you’ll just end up smearing what’s not been removed.
You may see some wiper ‘judder’ at the start but once it’s had a good bit of rain on it it’ll stop doing this.
Once you’ve done this you should see any water just sheeting off, the difference will be very noticeable.
