When you put it on, give the windscreen 2 coats before buffing / polishing. Each bottle should give you enough to do the front windscreen with 2 coats, plus a single coat on the rear windscreen. (I used a couple of bottles and did all the glass, including side windows and mirrors).
Also, wear surgical gloves or similar when applying the stuff - it stings if it gets into your skin, especially if you have any nicks or scratches (like I had from playing with the neighbour's Boxer pups). :D
And don't rub your eyes while using this stuff whatever you do .................. :eek:
