The repair kit haseverything you need in it,

including suitable liquid, a drill pad base, various

grades of abrasive paper,a foam pad and also a

microfibre cloth

I started with the coarse 800 grit disc fitted to the rotary

pad and concentrated on the scratched area. I took it easy

and monitored any heat build-up

8

I did this until I couldn’t feel

the scratches withmy

fingernail and then switched to the

1500 grit discs and repeated the

process. Don’t worry, it will look

cloudy at this point!

9

Still concentrating on the worst

area, I gradually worked through to

the fine 2000 grit abrasive disc

10

Once this felt smooth, I then

switched to the finest 3000 grit

abrasive pads. Don’t worryif it’s still

cloudy at this point – the clarity returns

with polishing

11

The final stage is to give the whole window a good

buffing with the liquid polish on the foam pad, paying

extra attention to any surface scratches

12

The results speak for themselves – good as new! If

you’re not happy with the end result, simply repeat

the process until you are happy
