Got skeptic when i first opened the package and saw 3 sandpapers and a bottle of transparent fluid, but decided to try anyways.
First i put on some of the sanding fluid and started to sand my headlights with a p600 paper and then i washed the headlight and starded sanding again with a p1000 paper washed it again and finally started with the p2000 paper. Then i washed my headlight and wiped it dry and when i saw the result i almost started to cry, but then i did the final step and wiped with a tissue that came with the kit and the result.. GREAT!
