This review is from: 3M Headlight Restoration Kit to Restore Dull/ Faded/ Discoloured Headlights (Automotive)
After trying the first headlight using water I realised that its much faster using the first 2 sanding pads dry. It seems to cut better. Then add water on the 3000 grit and the 800 grit scratches polish out well.
