Don't touch the inside of the lens. Even with a paper towel or microfiber. You will scratch the sh!t out of it. You'll only need to wetsand/buff the outside of the lens. Also, make sure you test fit them on the car BEFORE you seal up the headlights. You need to make sure the rotational adjustment is correct before you seal them up as the headlights on our cars sit at an angle.Originally Posted by laferri2
Also, I don't know if this is a problem with the aftermarket 'OEM' headlights for our cars or if it's for original OEM headlights too, but when you adjust them down with the projector in, you might notice that the projector will rotate counter-clockwise. And when you adjust them up, they will rotate clockwise. So you may need to compensate for that.
