Now you can see the foggy or yellow in plastic is gone but now there’s an identical white haze on the lens these are rubbing scratches.
- Now at the 1500 grit and start rubbing again, this time instead of going vertical, so you can remove the horizontal scratches. now you can see a little bit of haze.
- To remove the horizontal haze, use 3000 grit sandpaper and rub well horizontally and vertically to remove all the scratches.
In this step, you need a microfiber towel to use compound but you can use a hand, wool pad or you can use drill then you need a headlight polishing kit (drill is much quicker). Remove the masking tape and get some compound on the pad and start buffing, keep maintaining a consistent Spade with a uniform pressure with horizontal overlapping passes and then switch to vertical passes, get some polish to bring back the factory shine. now the clarity is back just like in a brand new headlight.
