not ALL of them, but over 90% went out, and some really deep onces are also fades away. Barely see it anymore. I'm sure it'll turns out better once you use your Meguiars plastic polish.
I used wet sand it with 1500 paper for a LONNGGG time, then used the 2000 to mid-dry sand it (I wet the lamp and sand it with dry paper, do it couple of times) then wet-sand it with 2000 to finish the touch.
wet sanding = nonstop watering and sanding at same time
FYI, before, people can know that I have Superwhites, Now, exactly the same my friend TL HID system (we parked and compared right after I finished putting things back on). I was amaze, can't tell the diff. He though that I had HID installed. I used Nokya 8500K Temp bulbs, even brighter than my PIAA Xtreme (now on my gf's).
